Since the establishment of the Yongsheng porcelain factory for half a year, Qian Duoduo's life can be described as very regular, during the day the government affairs institute is on duty and goes home to work overtime at night, so that the mother-in-law shouts to separate from him, people in their thirties are stunned to let a woman handle it to death, let him beat the dog he will never dare to pick chickens.

After Wang Xuan learned about it, he privately called him 'strict wife', but fortunately, he was very assertive in official affairs, and his mother-in-law rarely disagreed with her husband in this regard.

Jixiang now has a total of more than fifteen factories, and the young master let the Government Council manage it, but the Government Council let him manage it with a lot of money, so he has spent at least half of his time in various factories in the past six months, and it is no wonder that the family is separated. Wang Xuan's performance in the past six months is in his eyes and in his heart.

Today is June 10, 54 years of the Xia Yuan calendar, Qian Duoduo wants to go to the steel mill to place a batch of orders, and then check whether the precautions for safe operation are implemented, and check the implementation of 5S by the way.

These rules have been set at the beginning of the establishment of the factory, and the young master has specially instructed them. Everyone in the Council is planning a new city, and this kind of work is carried out by him and several ministers.

There are 10 earthen blast furnaces, but only two are currently in operation, one of which is to smelt pig iron, cast into brick-sized ingots and stored for later processing.

The other is the "frying steel" furnace designed and built according to Wang Xuan, the molten iron is directly fried after the furnace, and the crucible has not yet been made, so it has to be carried out in the mold built of refractory bricks.

According to the test of craftsmen who are familiar with the properties of iron, the performance of the steel produced by the new steelmaking method is much stronger than that of the steel produced by repeated forging of pig iron, and the ductility, toughness and strength have been improved.

These "fried" good steel is also divided into several kinds, because the size of the mold is the same, the quality of the steel produced by the different times of "frying" is also different, so there are three kinds of billets currently stored in the warehouse, namely the toughness, elasticity of the more prominent No. 1 steel, the moderate strength of the No. 2 steel, the harder but less toughness of the No. 3 steel.

Qian Duoduo's orders this time are all kinds of tools and molds mainly made of steel.

What the plate mill wants to order are planers, chisels, saws, hammers, and nails;

The mosquito coil factory ordered hammers, sickles, pickaxes;

The breeding factory ordered iron wire, castration knives (for pig breeding), kitchen knives and various slaughtering knives;

The cement plant ordered large crushed stone steel blocks, forging rollers, and transmission accessories;

The construction corps ordered more, shovels, pickaxes, shovels, sickles, axes, hammers, hacksaws, forks, etc.;

The quarry is single, with pickaxes, hammers, shovels, and saws as the mainstay.

Because the planned steel mill was only for smelting steel and there was no finishing process, the factory director Liang Dahai had to recruit blacksmiths from all over Jixiang to build various tools according to the requirements of the order.

When Wang Xuan learned about it, he set aside a corresponding area of land along the river below the steel mill to build a hardware factory, and these blacksmiths will be transferred to work in the hardware factory. In return, the blacksmiths bought half of the shares and led the management of the factory, and the insufficient shares could be paid in installments. The craftsmen are naturally happy like this, how can they be comfortable working for others as their own bosses.

Therefore, auspicious blacksmiths are scarce nowadays, and except for two blacksmith shops in the city, all the wild blacksmiths from other places have gone to the hardware factory.

According to the order, Niu Jing, the director of the hardware factory and a senior blacksmith, came up with a new way to shorten the construction cycle, and directly introduced the baked molten iron and molten steel into the mold, which saved time and effort in forging and improved the efficiency a lot.

Like a shovel, Niu Jing made a mold with refractory bricks, poured the No. 1 molten steel into the back cover, squeezed the upper cover a little hard, and after cooling, a piece of steel that resembled a shovel was formed, and after calcination, it was beaten, then calcined, beaten, and quenched, and the spade head was completed after several times.

Later, the tail is padded with an iron rod and beaten, and the wooden handle is attached and the iron nail is nailed.

Although the output of steel is not much, Wang Xuan has never hesitated in tool manufacturing, and everyone knows the truth that good steel should be used on the blade.

Wang Xuan was very appreciative of Niu Jing's "invention", and if it was used for mass production, it would not be possible to rely on manpower alone, so he thought of stamping.

To carry out stamping production, it is necessary to have a die, and under the existing conditions, it can only manufacture a die that presses the workpiece under high temperature, such as hot forging die, hot extrusion die, die-casting die, hot forging die, etc.

The commonly used hot work molds are alloy steel, with chromium, tungsten, molybdenum, barium and other alloying elements, as for the proportion God knows.

So when the first batch of 30,000 gold coins was purchased, Wang Xuan put some ores on the list, although he didn't necessarily know it, but it didn't hinder the smelting experiment, no matter what material could meet the better use standards, it was a good material, no matter if you called Zhang San or Li Si, it was a big deal to name it again.

Qian Duoduo naturally knew the Lord's thoughts, and this time he came to watch the production process of shovels on the spot.

He understood Wang Xuan's idea very well, if the refractory brick is turned into the negative side of the alloy steel mold, and the hammer becomes the male side of the forged alloy steel mold, as long as the strength of the yin and yang sides is enough, the heated billet will be quickly formed after being squeezed. He has seen a lot of factories in the past six months, and there are many whimsical ideas, many of which have been put into practice, and he is sure that Wang Xuan's idea can come true.

In order to realize this idea, we must first find a metal that improves the toughness, strength, and wear resistance of the mold.

The production of saws is interesting, using No. 3 steel, which is hard but brittle.

Niu Jing: They first sorted out the mold and poured in molten steel, and after forming, they took advantage of the high temperature to forge quickly, and repeatedly beat the saw surface evenly several times and then began to correct the sawtooth with pliers.

After this process is completed, the serrations are sharpened with a file and finally assembled. Qian Duoduo also deliberately found a piece of wood to try, and it was really much stronger than an axe, and it saved a lot of effort, but the saw surface was a little thick.

During the dinner in the evening, Qian Duoduo deliberately mentioned Wang Xuan's idea of hot forging die, which really aroused everyone's strong interest. It's all iron, how can you not understand the mystery?

Therefore, everyone has also said that they will increase the collection of metal ores, and work closely with the iron and steel mill to find this rare metal one day earlier and create high-quality products for the benefit of the auspicious people.

In the early morning of the 11th, Qian Duoduo and his entourage came to the cement plant, and the factory director Du Yi led a group of management personnel to greet them at the gate of the factory.

"Money is always good, money is always hard, and I am flattered to come to the cement factory to inspect this morning. Du Yi said with a greeting.

The title of 'Mr. Qian' is Wang Xuanqi's head, and the research institute is just him, so what is it if everything is not 'total'?

Qian Duoduo didn't care in front of the factory leaders, and after saying hello, the group came to the cement products tested.

There are three types of cement products used for testing, one is the condensate of pure cement mixed with water, the other is the condensate of sand cement mixed with water, and the other is the cement condensate with stone, sand and water. As for the respective proportions, there are also detailed records, try to find the best ratio of cement for various occasions.

Qian Duoduo doesn't talk nonsense, just one sentence, "Smash it!"

The test worker picked up the sledgehammer and smashed it hard, and the object made of pure cement was broken first after only three blows.

So the second piece was hammered, and the cement block in Gaza cracked completely after the workers hammered it ten times, and the recorder was also faithfully recording what he saw and heard.

The final test was concrete with stones and sand, and the worker struck the cement block with a hammer, but the cement block was still hard, only slightly peeling off, and when the third worker was replaced, the cement block was still holding on, and the inside was still intact.

Qian Duoduo ordered people to carefully record the details of this experiment, and the most basic conclusion was that cement could not be used alone, and it would be better to use hardness and strength in combination with sand and stones, and it could be used to pave roads, build bridges, and build houses.

Qian Duoduo also remembers other uses of cement, the most important of which is to build bridges with reinforced concrete, which requires cement to condense in water, which is the main purpose of his visit.

"Director Du, this experiment is very successful, I was still skeptical about the bridges and buildings on the sand table in the new city before, so I am convinced after that, haha. ”

"That is, the young master's foresight is very within the reach of people, and Mr. Qian, you are always guiding ......" A burst of sycophants came like a tide, and the embankment that shot straight was crumbling.

"Well, I still have one more thing, according to the young master's request, I want to do a separate underwater verification, that is, ......"

Qian Duoduo explained the purpose and process of the experiment in detail, and Du Yi also agreed, and arranged personnel to carry out the water condensation experiment of cement on the spot.

In order to get first-hand data as soon as possible to report to Wang Xuan, and in order to be able to go home in time to deliver public grain, Qian Duoduo spent another night in the cement factory, and he didn't know what his attitude was to go home tomorrow!

The next afternoon, Qian Duoduo received the news of the cement condensation, and then hurried to the experimental site, and everyone turned over the wooden barrel used for the experiment, and when the water ran out, the condensed cement block was exposed.

Qian Duoduo asked people to bring a hammer and beat it hard, which was not much different from the previous verification, and only a little skin fell off and some stones and sand came out after dozens of hammers.

Knowing a lot about concrete money is one of the qualities that the person in charge of the research institute must have.

The different proportions of sand and gravel affect the strength and hardness of concrete, some are compressive, some are tensile and need more tests.

After taking the box of cement, Qian Duoduo returned to Jixiang City.

"Yo, the money always comes back. Wang Xuan joked after seeing Qian Duoduo.

"Young master, don't make fun of me, now that everyone else calls me that, I'm very embarrassed. Qian Duoduo smiled innocently.

Wang Xuan immediately put away the joking mentality, and began to check it after seeing the wooden box brought by Duoduo.

He carefully rubbed the cement powder with his hands, the touch was a little rough, the particles were large, and the color was gray, but according to the experimental results that Qian Duoduo said, such cement paving, bridge repair, and building houses should be enough, so should the model house be built?
