Walking into the design workshop, Du Yande was taken aback, a piece of ground in the workshop was as black as if it had been burned by fire. The boiler looks to be still alive, but there is a big hole on the other side, and it is estimated that it leaked from here at the time. Fortunately, although the rivets, screws and debris that were flying and injured three onlookers from a distance, the few industrial team members who were in charge of commissioning were unscathed.

On the side of the boiler, Zhang Yuanzheng was disguising himself to check the parts that flew out, picking them up from time to time to take a look and putting them back in place, and comparing the trajectory of the flying out. Seeing Du Yande coming over, Zhang Yuan stood up, his round face had lost weight directly because of the hard work in the past few months, and now it has basically become a rectangle, and the original white skin has been directly tanned by many days of outdoor labor, which is a common feature of all the traversals, even the executive committee members are no exception. Zhang Yuan walked up to Du Yande and stretched out his right hand, Du Yande didn't look at it and shook hands with him, but found that Zhang Yuan's hands were full of black ash, and the two laughed, "How is it?" Lao Zhang, what is the problem with your stuff over there? ”

"Welding problem......" Zhang Yuan couldn't help but sigh and shook his head. The welding requirements required by the boiler are not easy to meet, fortunately this is just a leak and not an explosion, if it is an explosion, it is estimated that all of us present will have to hang up immediately. ”

"And what about the first few times?"

"It's the same the first few times, it's just a pipe leak, and the boiler can't withstand it when the pipe is done......"

"Didn't I check it with a flaw detector before and say that the boiler wall was fine?" Du Yande couldn't help but be a little stunned. "What about the steam engine?"

"Steam engine?" Zhang Yuan couldn't help but turn his head and look at the intact steam engine not far away, and smiled bitterly. "That thing didn't push the boiler twice at all, there was a problem, you didn't see the terrible scene of the whole workshop being steam at that time, fortunately it wasn't against the side of the stationer, otherwise it would have turned into shrimp paste on the spot."

"What are they doing?" Du Yande pointed to a few naturalized migrant workers who were pushing a welding machine cart not far away.

Zhang Yuan turned his head and looked at it again, "This is a naturalized person who has been newly arranged to learn welding technology. These guys who have undergone literacy training, at least can do simple arithmetic, know how to read pictures, and know 300 Chinese characters. ”

"They welded this boiler?" Du Yande's face was stunned, isn't this a joke?

"Think beautifully!" Zhang Yuan picked up a pipe on the ground that was twisted like a snake and looked at it. "Our current welding rods and everything are used in reserves, how can such a precious thing be squandered by them? They all showed me from the side and learned how to weld. ”

"Huh?" A voice sounded next to him, "Adu, why are you here?" ”

Du Yande couldn't help but turn his head to look, it turned out to be Yuan Zhenli, and his troops before retiring from the army were equipped with Jian-8 fighters, which can be regarded as a wonder among industrialized products. At the end of the 80s, China once sent a squadron to the United States for modernization, but the Americans tossed for a long time to make one end two big, the same two planes, the parts are not interchangeable, and finally the Americans were speechless, saying that they would simply design a new aircraft for China. It can be seen that the person who maintains the Jian-8 fighter is a god-like existence, and Yuan Zhenli was directly transferred by the industrial team to participate in the design of the steam engine. Anyway, there was no military threat at this time, and there were observation posts on the periphery, so he didn't need the assistance of his aircraft, and Zhang Yuan also promised him that once the development of the small steam engine was completed, he would give his steam bomber a project, which Yuan Zhenli ran over to help.

At this time, Yuan Zhenli was also like all the staff present, his face was covered with black ash, sweat was flowing one by one, and the sweat alkali and black ash on his clothes were also piece by piece.

"I'm going to come over and see what's going on here, and what support I need more." Du Yande shook hands with him and said.

Yuan Zhenli wiped the sweat on his face, "The situation here is still the same sentence, to improve the welding technology, in addition, the materials are not so easy to get, the steel plate we brought is not the kind of heat-resistant steel used for the boiler, and the boiler should be made of low carbon steel." ”

Zhang Yuan sighed and shook his head on the side, "At this time, there is no way, the boiler steel is made of hot-rolled medium and heavy plate materials, and the low-carbon calm steel smelted by open-hearth furnace or electric furnace smelted low-carbon steel has a carbon content in the range of 0.16%-0.26%. The metallurgical department is not willing to use open-hearth smelting, and now there is not enough electricity for electric furnace smelting, and all we have at hand now are materials brought from the old time and space, and if it explodes like this twice, it is estimated that even the materials for repair will be exhausted. ”

"Our materials are relatively brittle, and when working in a medium temperature and high pressure state, they must not only be subjected to higher pressure, but also subject to impact, in addition to fatigue loads, water and gas corrosion, not to mention, anyway, I think our smelting level is not up to standard, this steam engine is a considerable trouble." Yuan Zhenli took out his work gloves from his pocket, looked at them, and stuffed them back into his pocket. "And I think it's a bit biased for us to focus on the steam engine now, it's better for us to focus on the spinning machine now, after all, the cause of the industrial revolution is still through the textile industry innovation, doesn't it mean that there is not only grain but also cotton in the city of Champang? Gu Qingqian put forward a proposal to build a spinning machine loom in her internal report last time, and I think we can start from this aspect. After all, it is easier to make a spinning machine and a loom than a steam engine, and the power source does not only need a steam engine, but also through water and animal power, wind power, and at least we have an electric motor. ”

Zhang Yuan's eyes lit up suddenly, now the main problem is to establish an arms industry, although this steam engine is important, but it is not the most important, through water power can also provide power for forging machines and other products. Before the smelting industry entered the formalization, it was indeed a little inappropriate to invest so much energy in the development of steam engines, as for the towing power on the wooden track, it could be directly pulled by oxen and horses, anyway, it was only six or seven tons of carrying capacity, and it was enough to use animal power.

In the afternoon of the same day, Zhang Yuan's report on the development of spinning machines and looms was handed over to the office of the Executive Committee, and a small meeting of the Ministry of Commerce, the Ministry of Industry and the Executive Committee was held that night. Zhang Yuan of the Ministry of Industry naturally has no objection to the project he proposed, but Xiao Jing complained slightly, the vast majority of the spinning machines are made of wood, and the requirements for wood are very high, and now the traversal has cut down all the trees within three kilometers outside the camp, and every time he talks about this, Xiao Jing is laughing at himself, saying that he came to this new time and space in order to escape from a polluted time and space, and then continue to pollute this new time and space. There was not much discussion in the Executive Committee, and since the development of the steam engine was stuck in the material, it was better to solve the problems that could be solved in other aspects first. So the project of spinning machine and loom was decided that night.

Naturally, the so-called project of the cross-cutting people does not need to be developed at all, and the design of the Jenny spinning machine is directly found in the big library, and it can be copied as it is. This pioneer of the industrial revolution who was "kicked out by a man" is an excellent invention, and the spinning machine imitated by the crowd uses a water turbine to drive the spinning wheel to rotate, but because there is no water flow in the design workshop at this time, it uses an electric motor to drive and provide power for twenty vertical spindles at the same time. Because it is a wooden structure, the processing is relatively easy, Zhang Yuan did not sleep that night, and directly led the design workshop of the Ministry of Industry to work overtime to make a sample overnight.

When this legendary spinning machine appeared in front of everyone, all the onlookers couldn't help but marvel at the wisdom of the ancients. From a distance, the spinning machine looks like an organ, with the spindle at the bottom, and the spinning parts on top, and the processed fiber strips are fed from the inlet, where the yarn is continuously spun. This spinning machine is capable of spinning with cotton, wool and hemp fibers. The people of the industrial group took some of the cotton brought back from Champa Port last time and tried it, and the efficiency of spinning with 20 spindles at the same time was immediately revealed, and the 500 kilograms of cotton were quickly spun, so that the onlookers could not help but be speechless for a long time.

The Executive Committee hastened to have the Ministry of Construction build a spinning mill by the river and design a separate waterway so that the river could pass through the workshop to propel the turbines. When the construction team excavated the foundation and water diversion channel by the river, Zhang Yuan's design workshop successfully "developed" the hydraulic loom, and the effect was also very exciting, according to calculations, this hydraulic loom directly increased the efficiency of hand-weaving by 40 times, and the cloth spun from 500 kilograms of cotton turned into cotton cloth in a few hours, which made everyone even more jubilant.

In the midst of this jubilation, Pan Dai appeared in the office of the executive committee at an inopportune time, holding a document in his hand and handing it over to Yang Minghuan, who was on duty in the office. Yang Minghuan flipped through the documents, felt that his brain was a little insufficient, and was about to ask, Pan Dai spoke by himself.

"These weird people from the industrial group have gone to the crooked tech tree again, okay! What kind of water-powered spinning machines and water-powered looms, why not directly use hydroelectric power and then use electric motors to drive the spinning machines and looms to work? If the factory is not working, it can also be connected to the grid to let the electricity enter the grid for other departments to use. ”
