During the period when the steel mill was officially put into operation, several senior leaders of the alliance had confirmed the implementation of the alliance countermeasures submitted by Xia Lin.

After the establishment of agricultural cooperatives, Xinglan Industrial Park is responsible for providing iron and steel agricultural tools for the cooperatives.

Iron farm tools are good to say, with the processing capacity of steel machine tools, you can use the iron on the market to process a bunch of cooperatives in minutes, but steel farm tools can not directly on 1, 0.5, thin slabs.

Xia Lin's idea was to first hot roll thin slabs into 20-thick steel plates by means of a hot rolling mill, and then turn these steel plates into narrow steel sheets 5-10 thick and 200-300 wide by means of a cutting machine and a plate rolling mill.

Next, these narrow steel sheets can be directly used with machine tools to open, or further rolling mills can be used to turn these steel sheets into thin steel sheets to reduce the use of materials, after the opening can get very good hoes, pickaxes, shovels, axes and other agricultural tools and tools.

Therefore, Xia Lin must implement the steel processing plant as soon as possible to complete the production of narrow steel plates, short steel pipes and smooth round steel bars, which involves the research and development of hot rolling mills, plate rolling mills, shearing machines, free-fall forging mills and pipe rolling mills.

After the research and development of these machines, in addition to being able to quickly mass-produce steel farming tools and tools, providing a foundation for agricultural cooperatives, Xinglan Industrial Park can also have an extremely terrifying production capacity, that is, the cold weapons of this era.

By forging and rolling, steel mills can easily obtain large quantities of narrow steel bars, and such steel can be processed in batches to make long swords.

At that time, maybe we can rely on this technology to reach a certain cooperation with the military of the empire, and drive a nail into the nest of conservatives.

As for plate armor, Xia Lin still has a problem to solve, that is, the power provided by water power is not enough to drive the large rolling mill that Xia Lin wants most, which is why Xia Lin only considered the production of narrow steel sheets when planning the steel processing plant.

As the size of the rolls increases, so does the amount of power required, so today's steel processing plants do not have the capacity to produce wide and uniform sheets.

After holding a research and development seminar with the dwarf masters of the machine tool factory, explaining the working principle, use and accuracy requirements of these machines they designed, as well as the main difficulties, the seven dwarf masters and Xia Lin began a prosperous research and development project.

The first is a hot rolling mill that hot-rolls the thin slabs produced by electric arc furnace continuous casting into hot-rolled thick plates, which is a good machine to develop.

The main requirement is that the accuracy of ten to twenty rolls has some requirements, if you want to roll a 40-thick thin slab into a 20-thick hot-rolled thick plate, the roll diameter error can not exceed 5%, that is, 1, otherwise the surface of the hot-rolled plate will appear high and low uneven.

After this period of hard work, the machining accuracy of the steel lathes in the machine tool factory has approached this category, roughly around 1, and what Xia Lin has to do is to help the dwarf masters further upgrade the accuracy of the machine tools, especially the accuracy of the most critical component of the machine tool - the guide rail.

However, the spiral micrometer with the greatest improvement in accuracy is still lying on Xia Lin's drawings, and no matter how the dwarf masters process, they can't make a thousand fine threads on a nut that is no more than 10 years long, so Xia Lin can only think of other ways to help the dwarf masters.

After pondering for a while, Xia Lin quickly found a feasible idea based on his own experience.

That is, through a darkroom and a light source to obtain extremely straight light, and then use this straight line to find the error on the guide rail of the machine tool, so that the light of the comparison line can find the error on the guide rail and other machine tool components, and after grinding and correction, a certain precision can be improved.

This idea uses the principle of light propagation along a straight line, which was used in many places when Xia Lin's motherland was just beginning to industrialize, and it is the most basic laser measurement.

It's just that this method has high requirements for the operator's technique, although the human eye can distinguish the error of 0.1, but the fitter who can remove the error by hand in the dark room is rare.

Fortunately, Xia Lin still has a group of reliable fitters, and Master Faun listened to Xia Lin's explanation of the accuracy of the dark room light source

After the law, he nodded clearly, although he didn't understand what Xia Lin said for the time being, just spread in a straight line, but Master Faun was quite convinced of Xia Lin's words.

After entering the darkroom with the machine parts, Xia Lin performed a shimmering technique outside the hole reserved for the darkroom, and a thin but intense light entered the darkroom through this hole.

Master Faun was a little surprised to see this, but it mattered, and he soon began to polish the parts of the machine in the dark room with the help of this straight line, which was said to be absolutely straight, according to Xia Lin's instructions.

After a period of really dark work, Master Faun walked out of the dark room with his eyes wide open, and when he saw the sunlight outside, he immediately squinted his eyes, and it took a while to recover.

"How? Master Faun, does this work?"

Seeing Master Faun, Xia Lin couldn't wait to ask.

"It's useful, it's useful, but I'm definitely not going to do this kind of thing next time, staring at that light all the time, and almost blinding my eyes!"

Master Faun, who was rubbing his eyes, said angrily.

"It can't be helped, but if we can make glass and mirrors, we can make a light-focusing device in a wooden box, so that if we put a Shimmer Rune Disk inside, we might be able to get a laser.

This kind of laser can also form the light path that Master Faun saw in the darkroom in a relatively sheltered place during the day, and it will be much more convenient for us to measure and correct the accuracy at that time!"

Starting from the dark room in front of him, Xia Lin thought of another application of shimmering light, that is, laser measurement. I just don't know if the light produced by the shimmering technique can form a pathway in a relatively dark place on a sunny day.

Speaking of glass and mirrors, it is easier to solve, glass can actually be made by Xia Lin now, diatomaceous earth, caustic soda and lime can be fired soda-lime glass, but the process is more cumbersome, and the internal variegation and bubbles must be considered.

Compared to glass, Xia Lin felt that it was better to let the lapidary polish a few pieces of transparent crystal with natural crystal, and find a way to get some glucose and silver nitrate by himself, and the entire silver mirror reaction turned these crystal pieces into mirrors.

"Can you get that kind of light during the day? That's really useful!"

Hearing Xia Lin's thoughts on laser measurement, Master Faun nodded thoughtfully and said, he has already experienced the straightness of the light, if you can get such a straight and visible light in the daytime, it will definitely play a great role in improving the accuracy of the machine tool.

On the other side, the parts of the machine tool that have been corrected and polished have been assembled again, and Master Faun tried to process some components again, and found that the accuracy of this machine tool has indeed improved greatly, and the error can be controlled within 0.1.

In this way, with this machine, it is no longer difficult to machine those rolls.

Soon, cylindrical pig iron rolls and other parts of the hot rolling mill were machined by the skilled hands of the dwarven masters.

Charlin designed rolls with a diameter of 200 and a length of 500, and after assembling these rolls onto the frame of the hot rolling mill, a hot rolling mill with ten pairs of rolls with different clearances was completed.

Each pair of rolls will be heated in the furnace of the thin billet 2, after ten pairs of rolls finally get 2, 0.5, 20 thick hot rolled thick steel plate.

Although it is only hydraulically driven, this hot rolling mill, which can only be called small and has continuous rolling work, does not require high power, and the test rolling effect is very successful.

When the long and thick steel plates were produced, Xia Lin touched the cooled steel plates, and his heart was full of joy and emotion, and the dwarven masters were also amazed by the hot rolling mill, a machine that flattened and kneaded the steel like dough.

Starting today, the industrial park has finally taken the first step in the steel processing industry, and in the future, it is not necessary to directly process steel billets into components with machine tools, which causes great waste, but can be machined with various specifications of steel.
