Now the production capacity of the ironworks is declining, the original coal supply is not available, Meng Ming remembers that there is a coal mine in Pingdingshan, and the official road from Kaifeng to Nanyang just passes, Meng Ming found the Cao family, ready to cooperate in mining coal mines, and now the principal of the Cao family is Cao Ning's fifth grandfather Cao Xi, the father of Empress Cao of Renzong, who is now thirty-nine years old and a handsome middle-aged man. When Meng Ming saw him, he said what he meant, Meng Ming told him some of the situation in the Pingdingshan Coal Mine, he agreed, and drew up the charter, the proportion of the two families, Meng Ming six Cao family four, Meng Ming shirked, Cao Xi insisted, Meng Ming accepted. After Meng Ming left, Cao Ning asked: "Fifth grandfather, why is Meng Ming sixty percent of our family, are we a little lost" Cao Xi smiled and said: "Ning'er you don't understand now, the Cao family is taking advantage of others, he can do it completely by himself, he is doing this to show goodwill to my Cao family and give us a big gift." After that, he turned around and went out to arrange for relevant personnel to go to Meng Ming's place to go to Pingdingshan to survey and mine coal.

Meng Ming approached Chen Qinian and decided to let him participate in the design and manufacture of the steam engine, which is a reciprocating power machine that converts the energy of steam into mechanical work. Steam engine construction: The steam engine is mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve steam distribution mechanism, speed regulating mechanism and flywheel. The cylinder and base are stationary parts.

In a steam boiler, water is boiled into steam through the combustion process. Through the pipes, the steam is sent to the cylinder. The valve controls the time when the steam arrives at the cylinder, enters the slide valve chamber through the main steam valve and the throttle valve, and is controlled by the slide valve to alternately enter the left or right side of the cylinder to push the piston to move. The steam pushes the piston inside the cylinder to do work, and the cooled steam is introduced into the condenser through the pipe to re-condense into water.

This process is repeated constantly while the steam engine is in motion. A general steam engine has three cylinders forming a group. The steam engine directly converts the up and down motion of the piston into the rotational motion of the ship's shaft. The new steam engine also contains a small turbine, and the steam coming out of the cylinder can also use its waste heat to propel the turbine to improve the efficiency of the entire drive. This turbine is also connected to the ship's propeller shaft.

Meng Ming decided to use the Watt steam engine as a model, and Meng Ming's mobile phone had drawings of the Watt steam engine, which contained drawings of parts and components, and had dimensions. Meng Ming drew the parts according to the map, marked the size, and then found a carpenter to make a mold. It took 10 days to complete the drawings. It took five days for the carpenter to make the molds, and finally Meng Ming had the molds molded by the craftsmen of the ironworks according to the molds, and finally poured them with molten steel.

During this period, Meng Ming also designed a hydraulic lathe, prepared to process cylinders and pistons, so that they could accurately prevent air leakage, and looked for lubricants, which were the top priorities, directly related to the efficiency and life of the steam engine. He worked day and night on research, citing what I had taught him, and using physical formulas to calculate. Each component was carefully studied, and finally the mystery was mastered.

On the tenth day of the lunar month, Meng Ming and Chen Qinian were assembling steam engines, most of which were assembled by Chen Qinian, and his hands were dexterous than Meng Ming's, and he reacted faster than Meng Ming. They assembled it in half a day, they assembled it in the weaving workshop, debugged it for a long time, they started it, watching the flywheel turn, they shouted, let the steam engine grind for an afternoon, see the lubrication and wear, and let Chen Qinian count the efficiency of the steam engine. Meng Ming asked Chen Qinian to stay here and let him pay attention to the abnormality. He talked about several possible failures and how to deal with them, and Meng Ming went home. He secretly said that the era of the Great Machine had come, and the Great Song Dynasty would develop rapidly.

Meng Ming went home again to tidy up the steam engine used on the train. Preparing for the development of a steam locomotive next year. Meng Ming used the lathe to grind the bearing again, and let it destructive experiments, and then it was transferred to Chinese New Year's Eve, fifteen days, and it was still running normally. Meng Ming had already asked the carpenter to start making parts and molds for locomotive steam engines. He was a little anxious, and everything was calm.

On the eleventh day of the lunar month, Meng Ming went to the textile factory and saw that Chen Qinian had arrived, and he said in his heart that this guy was positive. The steam engine was already roaring, and Meng Ming walked up to Chen Qinian and found him yawning, his eyes were bloodshot, and his eyes were covered with bags under his eyes. Without waiting for Meng Ming to ask, he hurriedly got up and said, "Sir, I haven't slept all night, so I just stared at this steam engine, and I added water a few times, and how often I added it, I have a record of it, and it is running normally." I'm going to sleep, I'm sleepy, goodbye sir". Meng Ming secretly admired Chen Qinian, he was a piece of material, and he would be Meng Ming's key training object in the future. He looked at the lubrication of various components, the most important thing is the lubrication and wear of the cylinder and piston, Meng Ming carefully observed, everything was fine. Meng Ming was relieved and prepared to produce twenty units, which were placed on the coal mine for pumping water, oxygen and blowing air, Meng Ming calculated that the cost of this steam engine was roughly three hundred yuan. This cost was borne by him and the Cao family.

In his spare time, Meng Mingyou developed steel pipes, and he asked blacksmiths to use the 100-steel method, that is, to repeatedly beat the red-hot steel blocks to increase their rigidity, elasticity, and toughness. Meng Ming had invented a water conservancy machine to beat steel blocks before, replacing manpower to repeatedly beat steel blocks, which could be knocked hundreds of times, and now it is driven by a steam engine. This time it's a machine beating. The so-called 100 steels were made, and finally Meng Ming used 100 steels to make the cutter head of the lathe. The steel pipe was first made into a blank by casting method, and finally rounded with a lathe, and Meng Ming finally got only five steel pipes, with an inner diameter of 1.3 cm and an outer diameter of 2 cm. Meng Ming decided to make a rear-loading pistol, using a flint firing device, clamping a flint (flint) between the jaws of the hammer, and setting an anvil on the side of the fire transmission hole, if it was necessary to shoot, he would pull the trigger, and under the action of the spring, the flint would be hit heavily on the edge of the fire door, and sparks would emerge and ignite the gunpowder. It took five days to make it, with a flintlock mechanism in front of the wooden bend, a trigger below, and a charge chamber and barrel in front. Meng Ming adjusted the proportion of saltpeter, sulfur and charcoal of gunpowder, so that the proportion of nitrate accounted for three-quarters, Meng Ming calculated the amount of gunpowder, and wrapped the gunpowder with oily and flammable paper, and put it directly into the gunpowder bag each time it was filled, and it could be fired ten times a minute with a range of 50 meters. Self-defense is only enough, but it is a bit heavy, weighing four and a half pounds. Meng Ming is not on duty, so he carries it with him when he goes out.

Unknowingly, the four years of Tianxi will pass, tomorrow will be Chinese New Year's Eve, Meng Ming has been in the Song Dynasty for almost four years, after the year, Zhenzong will change to Yuan Qianxing (1022), also died in this year, the crown prince Zhao Zhen took the throne and became emperor.

The imperial court has a seven-day holiday for the Spring Festival as usual. Yuan Xi (the fifteenth day of the first month) has a ten-day holiday, Meng Ming also wants to take advantage of the New Year to rest, my father is still in his hometown to keep filial piety, and he has to keep it for a year and nine months, so I spend more time with my family and the jade cicada. This year, Meng Ming called the Jade Chan family to celebrate the New Year together, as well as Uncle Xiang's family, a pair of dragon and phoenix fetuses from Uncle Xiang's family, the boy is called Meng Yundi, and the girl is called Meng Shuzhen, both of whom are one year old and six months old. Uncle Xiang's sister Meng Mei also came to Tokyo, and now the family is very lively, and now the family still gets together on Chinese New Year's Eve, eating Chinese New Year's Eve dinner and keeping vigil. The meal was still ordered from Fan Lou, and now the steaming meal was set on the table, and the family was sitting together, laughing and laughing, and Meng Ming was satisfied. What is more important than family, looking at my two cousins and cousins babbling, happy and carefree, Meng Ming thought of his children in his previous life, his son Xiangqi should be twenty this year, his daughter Jiayu is also six years old, and the second elder is also in his old age, they are all fine, and I hope that everything is fine with my family in my previous life, and I hope that Yubao will grow up healthy and healthy. I saw Jade Cicada looking at the two children, her eyes were red, and her memory was still one year old and eight months old. Meng Ming comforted her. Now he understands that Meng Ming is desperately doing this and that, and rarely dealing with others, in fact, he can't let go of his previous life from time to time, so he keeps himself busy, so he tries not to think about those things. It's like an ostrich sticking its neck into the sand when it encounters danger, trying to escape but can't.
