Chapter 256 Ground Steel

However, although the construction of the earth blast furnace was relatively smooth and there were no major accidents in production, the matter of steelmaking was far from as simple as Xiaotian thought. After a period of smelting, it finally came to the time of steel.

However, the result made Yu Xiaotian very discouraged. The two earth blast furnaces simply failed to come out of steel and water, and there was sintering in the furnace, which means that the two earth blast furnaces were directly scrapped, and all the raw materials, manpower and material resources invested were also directly scrapped.

Although several other earth blast furnaces released molten steel after a period of smelting, after cooling, they were tested by experienced blacksmiths and found that most of them were not steel at all. Basically, they were still raw iron, which could not be used to make things at all, and could only be used as cast iron.

Yu Xiaotian is really speechless about such a result. No wonder in later generations, the three words earth blast furnace were scoffed as soon as they were mentioned. This thing really doesn't seem to be reliable enough.

After all, when many generations built earth blast furnaces, they also invited some so-called experts to provide guidance, at least some technical content, but he tossed this thing here, but it was all based on his own ideas. There was not even a person who could provide guidance. It was not easy to succeed.

After many days of tossing around, only two earth blast furnaces finally refined some steel that could be called steel. After the inspection of the blacksmiths, it was believed that this kind of thing was almost useful, at least much better than cooked iron.

Yu Xiaotian is a little relieved. After all, this time he invested huge manpower and material resources to build so many earth blast furnaces of different shapes for steelmaking. If all of them end up in failure, then not to mention the waste caused, there is no room for him to put his face!

You should know that now the sea wolf treats him as a god. There has been almost no failure in what he had done before. Now such a big movement has finally produced a pile of scrap, which undoubtedly hurts people's trust in him.

However, in the end, there were still two small earth blast furnaces that refined some sloppy steel, which more or less saved his face. Otherwise, Yu Xiaotian himself would feel ashamed this time.

Even if he can say that failure is a mother of success, it will still have some negative effects on his personal image.

However, at least the two small earth blast furnaces took a breath for him and refined some steel. As long as these two earth blast furnaces are successful, it will be much easier to make steel in the future.

Fortunately, Yu Xiaotian's strength has been strengthened a lot, so he dared to invest a lot of manpower and material resources to build so many earth blast furnaces for experiments. If he build an experiment like before, God knows that he will refine molten steel water and will be in the year of the monkey.

So after tossing for a long time, Yu Xiaotian finally confirmed that these two small earth blast furnaces could indeed produce molten steel. Although he could not carry out metall phase inspection for the time being, he could still use some earth methods to carry out some simple tests on these products.

Finally tested, some of the ground steels initially produced are low-carbon steel, some of which are medium carbon steel. Of course, some are high-carbon steels, which can finally be used. Although they can't all be used to build *, they can't be thrown away.

So he ordered the demolition of all the earth blast furnaces that had completely failed in the experiment, and adjust several promising blast furnaces after slag treatment. In addition, he drew on the structure of the two successful small soil blast furnaces and re-enlarged and rebuilt several slightly larger ones. The soil blast furnace began to carry out steelmaking production.

Although the quality of steel produced by these earth blast furnaces fluctuates greatly every time, steel is still refined. The next step is to see these craftsmen gradually exploring their experience. Yu Xiaotian requires the craftsmen in the steel mill to formulate a set of strict operating systems and norms, and produce according to the specifications. Industry.

Because this thing is definitely a high-risk industry, if it is not operated well, it may cause a fire or other serious accidents. Deaths are common. Shortly after production, when steel water is released again, there was an accident of steel splashing people, and two workers were burned on the spot. He was seriously injured and choked before he could be sent to the hospital.

In addition, Yu Xiaotian also instructed the craftsmen to weigh each feeding in detail, carefully record the proportion of feeding, and check the discharge situation. Finally, he gradually found a more practical method to ensure that the quality fluctuation is reduced when the steel is made.

Although steelmaking is full of twists and turns, at least steel is finally made. People will not remember those failures. What they are most concerned about is the successful steelmaking. When these craftsmen see these unfavorable earth blast furnaces, they can really make steel, so they suddenly rejoice again. .

Although this kind of earth blast furnace does not look good, it often has problems, and the quality of steel is unstable, but after all, it still produces steel, and each furnace can produce thousands of catties of steel at a time, which is much more than they used to make a little steel at a time with the stir-frying method and steel filling method.

With these steel, it made Zhang blacksmith very happy. For a long time, Zhang blacksmith has also had a headache about the quality of the barrel of the wolf-tooth rifle produced for the gun.

Because the barrel is made of cooked iron, after pulling out the river, a barrel can't shoot dozens of bullets, and the river will soon be bald, so that it can only be removed and replaced with a new barrel. The old barrel is brought back to the gun to either reload the reload or simply return to the furnace for remanuation, which is very wasteful.

Nowalong, steel has been made from the earth blast furnace, and now they finally have materials to replace cooked iron to make barrels. In the past, he has also used some craftsmen to make steel made by the fried steel method and steel filling steel methods to create a small number of barrels. After these barrels are pulled into the worm wires, after trial, the life of the barrel worm line is at least better than that of cooked iron. The built barrel is ordered to be extended by two or even five times, eliminating the trouble of changing the barrel frequently.

However, the quality of steel refined by that method cannot be guaranteed, and the quantity is really low and unacceptable. It is impossible to replace the cooked iron to build a barrel. It can only be used in a very small amount and is equipped for special forces or snipers.

Now Yu Xiaotian has finally come up with a way to produce steel in large quantities. Then the next step is to use these steel to replace the cooked iron to build a barrel. In the future, the number of wolf tooth rifles produced by gun production will increase day by day, and gradually replace those southern Japanese fang guns and become the owner of sea wolves. War equipment.

You should know that because the production quantity of wolftooth rifles has not been high, and a large number of spare barrels will be produced to be replaced as spare parts at any time, the sea wolf's army is anxious to scream, not to mention the navy that has been unable to equip wolf tooth rifles.

The navy now also has a naval company to station forts and cooperate with the navy to carry out operations. For such a long time, they have not been able to obtain wolf tooth rifles. For this reason, the navy people are also full of complaints and complain to Xiaotian without consent, so they often harass gunmen in private, complaining that their output is too much. Low.

The gunmen are now harassed by these guys and hide when they see them. Now with steel, this problem can be alleviated a lot.

So some limited steel that had just been produced, after inspection, could barely supply the steel used by guns, and were immediately robbed by guns and began to be put into production.

Unfortunately, the current output of soil blast furnaces is still very low, which is far from meeting their needs. This problem can only be solved after the new soil blast furnace is gradually put into operation and the steel output gradually rises.

In addition, as some high-carbon steel began to be produced, the development of bearings and gears was finally put on the agenda. Under the supervision of Xiaotian, Zhang Blacksmith began to work on this matter.

In fact, bearings and gears are not difficult. They are transparent at all, but it is not very simple to produce them. There are many technical problems to be solved. At the same time, they also need to find a way to make some machines to produce them. The inner coat of bearings must be made quite precisely without using precision. Higherer burrers and lathes are definitely not good.

If you expect to make it by craftsmen by hand, even if it can be produced, the cost will be frighteningly high, and the quality will certainly not work. Therefore, if you want to develop such a seemingly simple thing, you must first overcome the obstacles one by one.

Xiaotian is not very anxious. This kind of thing needs to be gradual. After a breakthrough, with the development of the working mother machine, a high-precision machine can be produced. Everything needs to be done slowly. It is impossible to eat a fat man in one bite.

At the time when steel was making in full swing on the side of Tamsui City, things on the other side of the dog port were also progressing steadily. In two or three months, the sea wolf has invested nearly 10,000 manpower and countless materials in the dog port, making the work there progress relatively smoothly.

With Ma Tiancheng, a cruel guy sitting there, these hard laborers were dissatisfied. At first, after making some trouble, they saw Ma Tiancheng kill him immediately by thunder, and the rest of the messy hard laborers did not dare to come.

Therefore, the construction of Dagou Port wharf took only three months and is almost completed. Now Dagou Port wharf has built six trestles deep into the sea, and at the same time, it can be used for more than a dozen ships to dock to load and unload goods at the same time, which greatly increases the material throughput capacity of Dagou Port.

As for the local indigenous tribes, when the sea wolf first began to land, they saw that there were not too many sea wolves. They attacked the dock area and the camp many times, trying to drive these outsiders away from the dog port.
