At that time, when Li Xiang proposed the manager of the heavy machinery factory, Lu Wenxin immediately thought of this person. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoZhao Ziheng is very proficient in large machinery, especially large hydraulic machinery. Prior to this, all the mining machinery of the Great Song Dynasty was manufactured by this person, although these mining machinery were not as complex as in later generations, but also used some simple wooden mechanisms, Li Xiang heard about this person's situation at that time, and immediately borrowed it.

Li Xiang saw him running in a hurry, and greeted him with a smile and said, "Master Li, slow down, there are pits dug everywhere here, be careful of falling." ”

Zhao Ziheng said with a smile: "It's okay, the lower officials are here to supervise the work every day, even if they close their eyes, they won't make a mistake." As he spoke, he got closer, and asked cautiously, "My lord, do you think this roadbed meets the requirements?" ”

Li Xiang nodded and said, "There should be no problem." Although each carriage is only designed with a load capacity of 20 tons, the roadbed made by this method is estimated to be able to withstand nearly 100 tons. But those forging pedestals are so heavy that they don't know how to transport them in and put them in place? ”

Zhao Ziheng said: "What my lord said is that in the current situation, this roadbed is naturally not much of a problem, but the installation of the base is extremely troublesome, but Xiaguan has already thought of a solution." When it is time for all kinds of large-scale machinery to be installed, it is only necessary to build a temporary railway, transport the parts to the right location, and dismantle the car and the railway in place. ”

Li Xiang said with a smile: "This method is really good, it doesn't hurt to use it temporarily, but it won't work in the long run." ”

Zhao Ziheng also smiled: "This is natural, at present, the laboratory is already designing train cranes, and there will be small mobile cranes in the factory, but at present, these machines are just some drawings." ”

Li Xiang said again: "Most of the parts of these forging equipment have been made, and I heard that some pneumatic mechanisms are still being designed, if they are all installed, I'm afraid it will take a while, right?" ”

Zhao Ziheng said: "That's right. However, there is no rush to install the equipment right away. Now the drainage, water supply, steam pipes, wires and pipelines are under construction, and it takes more than ten days to complete the pipeline alone, and there are also driving tracks in the making. As for the railway in the factory, although the roadbed has been paved, the rails are not yet in place, so it is estimated that it will take a month or two to complete the construction of the entire plant. ”

Li Xiang nodded and said, "Yes, this kind of thing can't be rushed." Although it is only a forging and rolling workshop, there is still smelting equipment to be built outside the workshop, and it is necessary to lay railways and erect cranes, which obviously cannot be completed in a short time, and it seems that this progress is still slower than I imagined. ”

Zhao Ziheng hurriedly said: "My lord, please rest assured. The base of the forging press has been cast a few months ago, although the rails used in the workshop have not been laid, but they will be ready in a few days, and the rough parts of the wheels have been processed more than half, but the timeliness of the base mentioned by adults cannot be solved. ”

Li Xiang said: "This is also something that can't be helped. Natural aging usually takes years, and if the parts are too bulky, it can even take more than ten years, which cannot be replaced by any method. However, at present, we are in a hurry to use it, so we have to deal with it in this way, but fortunately, we have prepared dozens of other pieces, so we can use them directly in a few years. Besides, isn't it true that many devices are now made of wood instead of wood? ”

Zhao Ziheng nodded and said: "Yes, for example, this car is made of wooden stakes as supports, and then thick wooden strips are placed on top of it as rails, and the lower part of the wooden strips is reinforced with ejector rods, and iron guide rails are fixed above." ”

Li Xiang said with a smile: "This is also true, for heavy factories, the role of the crane is naturally obvious, but what is the carrying capacity of the girder of this crane?" ”

Zhao Ziheng said: "Although the girder is also made of wood, iron plates are used under it for reinforcement, and a variety of ejector rods and cables are used to reinforce, so it should not be a problem to transport a ton of goods." ”

As they spoke, they walked to the corner of the factory. Zhao Ziheng pointed to the dense pipelines on the roof and said, "My lord, this workshop is designed to be extremely large, and the total length of the pipeline has exceeded more than ten miles. Fortunately, the design drawings are extremely detailed, so you won't make mistakes in the busy. He added: "There are five forging presses on the south side of this plant, and two rolling mills and a hydraulic press on the north side, all of which were built according to the original design. ”

Li Xiang said with a smile: "It sounds complicated enough, but this plant is made of bricks and wood, and the steel ingots are burned red hot during processing, I wonder if the structure of the plant can meet such high temperatures?" ”

Zhao Ziheng hurriedly said: "Adults can rest assured. The iron dies used in rolling mills and stamping machines are fed directly through the conveyor holes in the wall. Next to the wall is the casting room, which is equipped with a regenerative chamber and a melting furnace, and the molten iron can be refined by the converter to obtain the required iron ingots, and then passed through the rolling mill and hydraulic press to make suitable profiles. As for the steel with higher quality requirements, it can be cast by air hammer forging machine, and then after quenching and tempering, the ingot can be obtained. ”

The two talked for a while, and Li Xiang had fully understood the current progress. The design of the factory room fully meets the requirements of the laboratory, and it is combined with the situation at that time, and there are some new ideas. Li Xiang was already enthusiastic when he heard it, and he only felt that the industrial age had arrived, but then he thought that although the factory building was built, there was still no decent equipment in it, and although the roadbed of the train track was paved, the rails could not be made in batches, so he couldn't help but feel a little anxious.

In fact, Li Xiang is still satisfied with the current progress. As the saying goes, 'everything is hard at the beginning', just like the first lathe, neither accuracy nor function can be guaranteed at the beginning. But since the first lathe, it has been possible to build a second lathe with higher precision. Now Lu Wenxin and others have begun the design of the fourth generation of lathes, and drilling machines, milling machines, grinding machines, planers, boring machines, etc. have begun to replace, although the quality of tools still needs to be improved, but at least in terms of quantity can be satisfied. In this way, the next step to consider is how to fully develop.

After walking out of the heavy machinery factory, Li Xiang did not get into the carriage, but walked aimlessly in the royal laboratory alone, thinking to himself that it has been a year and a half since I came to the Song Dynasty, and now I can't even make a train track in batches, is it really so difficult to have an industrial exhibition? Suddenly, I thought that now that there is a rolling mill, it is equivalent to a new tool, and now that the iron production has increased greatly, it is not difficult to make other heavy machinery, at least it is much easier than making the first one.

Li Xiangzheng thought to himself, and when he looked up, he had already arrived at the door of another factory that had just been built, which was the electrical appliance factory that he attached great importance to. (To be continued.) )
