After Yang Peng finished dinner, he called Zhang Xiang and Zhao Jinxi to the study together. Let's talk about the way back. Yang Peng said to Zhang Xiang, "Big brother, it is difficult for us to have great development if we continue like this, and we are facing a behemoth like Liao, there is no reliable base, that is, there is no future, that is, it is a joke with the lives of our brothers, I wonder if we should build a city first, develop agriculture and other industries, and develop the army, the Great Song Dynasty is not dependent on us, their backbone has been broken, in addition to the imperial court's emphasis on literature and light on military force, it is not bad if we don't encircle and suppress us with the Liao State, don't expect them to help, I just want to build a city by the sea in the east of Cangzhou, so that I am not afraid of the encirclement and suppression of the Khitan army, big brother, where is we looking for a piece of land by the sea in Cangzhou now, where will we take root first, and slowly collect some refugees first, what do you think? ”

Yang Peng said, "This is the best, we are now like headless flies everywhere, this will definitely not work, and our goal is to recover the sixteen states of Yanyun, if we have to have cavalry weapons against the Khitan, so that it is possible to have hope of recovering the sixteen states of Yanyun," Zhao Jinxi said, "Big brother, isn't it?" We only have a few people now, and even if we are developing, we don't have the ability to recover the sixteen states of Yanyun. Even the imperial court can't do it, and how much money does it cost. Yang Peng said to Zhang Xiang and Zhao Jinxi, "Our early development is to rely on refugees, there is no money, those landlords, Haoqiang, they have it!" As long as the people are not good for the people, the strong and the landlords are our financial resources, so that we have the people's heart, the people's heart is the source of money, and the poor people of Liao are also the objects we strive for, in terms of weapon transformation, big brother, you have to help us find those who have blacksmiths, carpenters and other craftsmen, and we still have nearly 1.5 million taels of silver, we will stabilize for a period of time, and at this time, do not attack the Khitans, and wait for us to have a certain strength to save the iron ore first. Hands-on on Yingzhou and Mozhou. Let's take it one step at a time. Also, inform Yang Tong that they should also pay attention to the Khitan schemes. Preserve strength. ”

Yang Peng said to Zhang Xiang, "We will go east to Cangzhou starting tomorrow to find a place, where to find a place to build a city, and where to find a place where we can live temporarily, Zhao Jinxi, you stay here, and the second class will go with us to take care of it," Zhao Jinxi looked at Yang Peng with an unhappy face. I had no choice but to nod and look at Yang Peng with some reluctance. I hope Yang Peng will change his mind.

Yang Peng and Zhang Xiang, Zhao Jinxi began to observe in the camp for a while after discussing, at this time there were less than a hundred people here, Yang Peng no longer dared to act rashly, because he could not afford to lose, and it could not play a big role, now the most important thing is the development stage, without a strong strength, it will not work, just look at how this trip to Cangzhou is, the most important thing is that there must be the will of the people, so that they can have reserve military strength to develop. Only in this way can we be sure of recovering the sixteen states of Yanyun. Yang Peng didn't know why he had such a big desire for Yanyun Sixteen Prefectures, Yang Peng was thinking about who he was, who his parents were, and who else in his family was in this world, could he be an orphan, even if he was an orphan, he had to know where his hometown was. Thinking about Yang Peng gives me a headache, eh.

Yang Peng didn't want to think about it anymore, his head hurt to death when he thought about it, Zhao Jinxi returned to his room, Zhao Jinxi didn't know why Yang Peng was in front of him, but he felt that he was still not worthy of Yang Peng, and he was also thinking that even if he just stayed by Yang Peng's side, thinking about Zhao Jinxi's face was already red, fortunately, Zhao Jinxi had experienced so much and felt that his heart was in turmoil, and Zhao Jinxi felt that his spring was coming.

Zhang Xiang is arranging the work of the left-behind personnel, as well as the training of the army, and arranging ten days of dry food, because tomorrow Zhang Xiang will go to find a new base with Yang Peng, and it is also for everyone's future thinking, Yang Peng is also preparing follow-up arrangements, this is also no way not to think about the chaos now, because this can not afford to lose, since you must also have a goal with everyone, because the Khitan still has nearly 400,000 cavalry, this is not something that you can win by making a small fuss, Yang Peng is also thinking about his brothers in the future.

Early the next morning, Yang Peng took Zhang Xiang, Zhou Dayong and others to Cangzhou to rest assured, Yang Peng took the map of Yingzhou, not to mention that the map of the Khitan is better than the map of the Great Song Dynasty, the strength is correct, Yang Peng and his party went all the way east from Cangzhou, basically no ordinary people appeared at this time, because the Khitan people like to play grass valley, here is already thousands of miles of barren, a desolate, Yang Peng sighed, this is the result of the war. Yang Peng walked for two days, this time he saw the sea, walked for five days and saw a hill of less than two hundred meters, Yang Peng had already made up his mind at this time to go north, and the front is also a mountainous area, but also not big, just three hills of less than five hundred meters, Yang Peng settled down and settled here, because he basically no one bothered himself here, between the Great Song Dynasty and the Liao Kingdom, the Great Song Dynasty here can't manage here, all are wasteland, the land is fertile, as long as the grain is planted here, there will be a bumper harvest.

Since Yang Peng has settled down, he will go back first, and then take everyone here to settle down. After settling down, Yang Peng also explained to Zhang Xiang the benefits here, and there is no local force in the development of the two years, the landlord Haoqiang came to earn this place with himself, Yang Peng and Zhang Xiang said, "You and they go back and arrange personnel to come over." In arranging for the personnel in Yingzhou to buy food, cloth, iron, and take in beggars and people in distress, that is, no matter who we want, and where in Cangzhou we also have to arrange personnel to take in those people in distress, buy chickens, ducks and geese, and piglets, etc., just spend money to buy it, I will see here how to build a brick kiln first, and I am looking to see if there is iron ore here, if not, see how we can get those iron ore, you go back and discuss with Zhao Jinxi, okay That's it. I'll just have five of you here. Zhang Xiang thought about it, there was no way to do it, Zhang Xiang took the people of Chengyu back to the secret camp, Yang Peng and the people of Chengyu began to look for iron ore and stones, as well as coal mines.

Yang Peng thought about things, other people were already arranging tents and food, the next day Yang Peng began to build an earthen kiln with everyone according to his own ideas, Yang Peng's team burned bricks of the earthen kiln seemed to be very familiar, after five days of hard work the earthen kiln was built, Yang Peng began to make adobe molds again, Yang Peng taught Zhan Jinguo to do this, Yang Peng went to the mountains to get some game to improve the food for everyone, Yang Peng did not long enter the mountain to hit nearly ten hares and a few pheasants, when he returned, he saw that everyone was busy, On the way back, Yang Peng also found that there is a coal mine here that is not very big but enough for himself to develop here for ten years, and now ironmaking is made of wood, as long as coal is used, steel.

Yang Peng spent ten days to visit all the mountains here, not to mention the big harvest, there is really a lot of game here, there are even millet deer, goats, there are still a lot of wild goats here, Yang Peng is very happy at this time, the first batch of bricks are about to start burning, Yang Peng is also very serious about how to tell them how to burn the kiln. When it was almost fifteen days later, Zhang Xiang and the others returned, and this time they brought nearly 500 people, as well as nearly two white carts and nearly 100 horses. Yang Peng was so happy.

Zhao Jinxi looked very haggard, Yang Peng stepped forward and hugged Zhao Jinxi, and then hugged Zhang Xiang, separated for a long time, and then Yang Peng said to everyone, "Hello fellow countrymen, I am your head, here we are going to start to implement our ideals, there is no oppression here, there is no high and low here, everyone is equal." This is also our beginning, now we have to develop from here, don't look at our few people, the spark can start a prairie fire, as long as we have ideals, we will definitely do it, blacksmiths and other craftsmen to Zhang Xiang where to sign up, can farm to Miss Zhao where to sign up, and less than twelve years old to Liu Zhiliang where to sign up, in the future all children must go to school to read, including girls, no one can stop it. This is our main policy. All right. Let's arrange to stay first. Zhang Xiang, you arrange for 20 people to go to the brick kiln factory to help, and in the future, we will all have brick houses here, and there will be no more thatched houses. ”

Zhao Jinxi took a group of girls to a place not far from Yang Peng and began to set up camp, and Yin Mingde took twenty people to start training. Yang Peng asked them to buy a large number of items from the four cities this year, buy grain seeds and other vegetable seeds, and the blacksmith shop also began to build ploughs. In terms of color, the color of wood is cold, while iron is also cold, which can achieve visual balance; The ploughshare is V-shaped, which is a kind of symmetry, which can give people a comfortable, solemn and serious feeling, and symmetry itself is also a good balance.

Stability is mainly manifested in two aspects: physical stability and visual stability. From the modeling point of view, the plough wall, plough bottom, and pressure bowl below, the volume and mass are larger, the center of gravity is lower, and there is a strong stability, which is the actual stability; From the perspective of visual balance, the plough frame is made of wood, and the ploughshare below is made of iron, because the mass fraction of iron is larger than that of wood, so as to give people the feeling of the center of gravity moving downward, and there is a strong sense of visual stability. In product modeling, change and unity are a very important aesthetic law, which can also be called the general law of formal beauty. The main form of change is contrast, which refers to the degree to which certain parts of the shape are prominently represented. Unity mainly refers to the consistency of form and function and the consistency of overall style. In order to obtain the change and unity of product modeling, the main modeling techniques used are: seeking unity in change; Seek change in unity.

In the Tang Dynasty Quyuan plough modeling, although there are straight lines of the plough bottom, the pressure of the plow, the forehead, the plough arrow and the curved plough and plough tip, but their connection methods are the same, most of them are connected and fixed with the wedge, tip and tenon, and the main body is mainly a straight line. This is to seek unity in the midst of change.

In the Tang Dynasty Quyuan plough modeling, the straight line type is the main type, giving people a tough and stable feeling; However, the curves of the plough wheel and the plough tip make the shape full of variety, giving people a dynamic feeling, playing a role of contrast and contrast. The curved plough is mainly made of wood, and the iron ploughshare contrasts with the wooden plough frame, which is to seek change in unity. Yang Peng and the others already had a large amount of pig iron in stock at this time, which was enough for themselves for a year at this time, and Yang Peng also began to arrange for carpenters to make carriages. 1. What is the chassis and steering components of the four-wheeled carriage. 2. The carriage of the carriage should not be Western-style, but changed to the Chinese bridge, how to do it. 3. The Western-style carriage is pulled by a belt, and if it stops, the inertia of the carriage will not collide with the horses, and how to solve it in reality. To make a small carriage that can be pulled by dogs, in reality we don't have four wheels... 4. What is the chassis and steering components of the four-wheeled carriage.

After two days of hard work in his tent, Yang Peng finally drew the drawings. There is also the manufacturing method of bearings, which are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and their prices are higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

Bearing is an important basic component of all kinds of mechanical equipment, and its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. In mechanical products, bearings are high-precision products, which not only need the comprehensive support of mathematics, physics and many other disciplines, but also need material science and heat treatment technology, so the bearing is a product that represents the country's scientific and technological strength. Needle roller bearings are equipped with thin and long rollers (the length of the rollers is 3~10 times the diameter, and the diameter is generally not more than 5mm), so the radial structure is compact, and its inner diameter size and load capacity are the same as those of other types of bearings, and the outer diameter is the smallest, especially suitable for supporting structures with limited radial installation dimensions. Needle roller bearing according to the use of different occasions, can choose no inner ring bearing or needle roller and cage assembly, at this time with the bearing matching journal surface and shell hole surface directly as the bearing of the inner and outer rolling surface, in order to ensure that the load capacity and running performance is the same as the ring bearing, the hardness, machining accuracy and surface quality of the shaft or shell hole raceway surface should be the same as the bearing ring. Application: The combined needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components, which is compact in structure and small in size, high in rotation accuracy, and can bear a certain axial load while bearing a high radial load. And the product structure is diverse, adaptable and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system design very compact and flexible.

Self-aligning ball bearing: a bearing equipped with drum rollers between the inner ring of the two raceways and the outer ring of the raceway with a spherical surface. The center of curvature of the raceway surface of the outer ring is the same as the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and housing are deflected, it can be automatically adjusted without increasing the bearing burden. Spherical roller bearings can withstand radial loads as well as axial loads in both directions. The self-aligning ball bearing has a large radial load capacity, which is suitable for heavy loads and shock loads. The inner diameter of the inner ring is a bearing with a taper bore and can be mounted directly. Or use an adapter sleeve and disassembly cylinder to install it on a cylindrical shaft. The cage is formed using steel plate stamping cage and polyamide. Self-aligning ball bearings are suitable for bearing

Yang Peng also began to build a small blast furnace According to Yang Peng's experience, it is necessary to work hard from three aspects: raw material management, furnace operation, and equipment maintenance, among which it is particularly important to strengthen raw material management. The central requirement for improving the quality of pig iron is to minimize the sulphur content in pig iron. Sulfur comes from coke and ore, and to eliminate it, we should first shut down the raw material and restrict it from entering the furnace. This is the same as the implementation of the principle of "prevention first" in health work, and when the work of prevention is done well, the task of treatment will be greatly reduced; Eliminate sulfur from raw materials to a minimum, and desulfurization in smelting is easier to do. In desulfurization before smelting, the contradiction is single, the operation is simple, and the result is twice the result with half the effort; Bringing a large amount of sulfur to the furnace for processing will cause a series of changes in the slag ingredients in the furnace, which is much more complicated than desulfurization before smelting. The successful experience of small blast furnaces in many places shows that the basic requirements of raw material management are "coarse grain fine cropping" and "fine grain intensive cropping", so that the blast furnace can eat fine grain and clinker. By doing this, the improvement of pig iron quality has the most basic guarantee. But this requires a series of meticulous work.

In addition to coal mining, coal washing, coking, mining, mineral processing, and sintering should strive to improve product quality, from the perspective of iron-making plants, the main thing is to grasp the five links of roasting, crushing, washing, weighing, and feeding, to get rid of the "four evils" of mud, soil, foam, and impurities (impurities), and to implement particle size grading, quality classification, mixing and storage, furnace fixing, and strengthening charge testing. These measures mentioned above are fundamental measures to improve the quality of pig iron and increase pig iron production. After layers of checks and measures, most of the sulfur in the raw materials has been removed, and the rest of the sulfur has to be processed in the smelting process. The successful experience of small blast furnaces in many places shows that improving the desulfurization efficiency in smelting, that is, the central link of increasing pig iron output, is to implement the operation method of high smelting intensity, high air temperature and large air volume; Second, it is necessary to strengthen technical management, improve operating procedures, establish a responsibility system, and establish a good production order. In order to ensure the continuous high quality and high yield of small blast furnaces, it is also necessary to strengthen equipment maintenance, formulate reasonable maintenance procedures, prepare necessary spare parts and spare parts, and do everything possible to fight against accidents. If these tasks are done well, the machine can run normally and the blast furnace molten iron can flow for a long time.

Yang Peng arranged for 50 people to go to the coal mine to start digging coal, and talked about good ideas and methods, and arranged for 100 people to start building houses, Yang Peng and they burned out all red bricks, red tiles, red bricks are made of clay, shale, coal gangue, etc. as raw materials, crushed, mixed and kneaded by manual or mechanical pressing, and then dried at a temperature of about 900 degrees Celsius with an oxidation flame fired into sintered building bricks. Also called clay bricks. The technical marking of red bricks is generally 75 to 100. Ordinary sintered bricks (red bricks), also called standard bricks, are 240*115*53. (in mm) The color is bright red, sometimes dark black. Ordinary clay bricks not only have certain strength and durability, but also have certain advantages of thermal insulation and sound insulation because of their porousness. Therefore, it is suitable for wall materials, and can also be used for masonry columns, arches, chimneys, floors and foundations. Old-fashioned buildings mostly use it as a building material, where clay, waste or other local resources are the main raw materials, made by different processes, and the bricks used for masonry load-bearing and non-load-bearing walls in construction are collectively referred to as wall bricks.

With clay as the main raw material, the sintered ordinary brick is referred to as clay brick (symbol N) after batching, billet making, drying and roasting. When the brick kiln is roasted in an oxidizing atmosphere, red bricks are made. If the brick is fired in an oxidizing atmosphere. Then in the reducing atmosphere, the kiln is used to reduce the red high-valent iron oxide in the brick to the blue-gray low-valent iron oxide, that is, the green brick. Green bricks are stronger than red bricks, with good alkali resistance and strong durability. But the price is more expensive than red bricks.

According to different roasting methods, sintered clay bricks can be divided into internal combustion bricks and external combustion bricks. When the bricks are fired to a certain temperature in the kiln, the fuel in the body is burned and the porcelain is formed into bricks. Compared with external bricks, internal combustion bricks save a lot of external coal, save 5%-10% of raw material clay, increase the strength by about 20%, reduce the apparent density of bricks, and enhance sound insulation and thermal insulation performance.

When the bricks are baked, the fire should be properly controlled to avoid under-fired bricks and over-fired bricks. The underfire brick has light color, dull percussion sound, low strength, large water absorption rate and poor durability. The over-fire bricks have a dark color, a crisp sound when struck, high strength, and low water absorption, but they are mostly bent and deformed. Under-fired bricks and over-fired bricks are unqualified products. (1) Basic physical properties The standard layman size of sintered ordinary bricks is 240 * 115 * 53 mm, and with the addition of 10 mm masonry ash joints, 4 bricks are long or 8 bricks are wide, and 16 bricks are 1 meter thick. 512 bricks are required for 1 cubic meter of masonry.

(2) Appearance quality The appearance quality of bricks mainly requires that the height difference between the two surfaces, bending, impurities protruding height, missing flute corner size, crack length and complete surface meet the specifications.

(3) Weathering resistance Weathering resistance refers to the ability of bricks to resist damage under long-term wind, rain, freeze-thaw and other comprehensive conditions. Sintered products with small open porosity and small water saturation coefficient have strong weathering resistance.

(4) Frosting and lime bursting Frosting is a salt precipitation phenomenon in the use of bricks. After the excess soluble salt in the brick is dissolved by moisture absorption and water absorption, it migrates to the surface of the brick with the evaporation of water, and crystallizes and precipitates under supersaturation, so that the surface of the brick is a white attachment, or produces expansion, so that the brick surface and the mortar plastering layer are peeled off. For high-quality bricks, frosting is not allowed, and qualified bricks must not be severely frosted. Lime bursting refers to the phenomenon of explosion and bursting caused by lime blocks mixed with lime blocks in the brick body, which absorb moisture and mature. For high-quality bricks, it is not allowed to have a burst area with a maximum damage size greater than 2 mm; For qualified bricks, it is required that the burst area with a damage size greater than 15 mm is not allowed.

After all, what happens next, let's see how it will be broken down next time.
