However, although the construction of the earth blast furnace was relatively smooth, and there were no major accidents when it was put into production, the steelmaking thing was far from being as simple as Yu Xiaotian thought.

But the result made Yu Xiaotian very discouraged, the two earth blast furnaces simply failed to produce molten steel, and sintering appeared in the furnace body, which means that the two earth blast furnaces were directly scrapped, and the raw materials and manpower and material resources invested were also directly scrapped.

After a period of smelting, the molten steel was released, but after cooling, experienced blacksmiths were sent to inspect it, and it was found that most of them were not steel at all, but basically pig iron, which could not be used to make things at all, and could only be used as cast iron.

Yu Xiaotian was really speechless about such a result, no wonder in later generations, the three words of earth blast furnace were scoffed at as soon as they were mentioned, this thing really didn't seem to be reliable enough.

After all, when many places in later generations were building earthen blast furnaces, they also invited some so-called experts to provide guidance, at least some technical content, and he tossed this thing here, but all with his own ideas, not even a person who could provide guidance, and it was indeed not easy to succeed.

After several days of tossing and turning, only two earthen blast furnaces finally produced some molten steel that could be called steel, and after the blacksmiths' examination, it was thought that this kind of thing was almost usable, at least much stronger than wrought iron.

Yu Xiaotian is somewhat relieved, after all, this time he has invested huge manpower and material resources in order to make steel, and has built so many earth blast furnaces of different shapes, if they all end in failure, then not to mention how much waste has been caused, there is no place for him to put his face!

You must know that the sea wolf now treats him as a god, what he had to do before, almost never failed, and now he has made such a big move, but in the end he has smelted piles of scrap iron slag, which undoubtedly hits people's trust in him.

However, after all, there are still two small earthen blast furnaces that have smelted some so-so steel, which has somewhat saved some of his face, otherwise Yu Xiaotian himself will probably feel embarrassed this time.

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

However, this time, the two small earthen blast furnaces fought for him and smelted some molten steel, as long as these two earthen blast furnaces succeeded, then the steelmaking will be much easier in the future.

Fortunately, now Yu Xiaotian's strength has increased a lot, so he dares to invest a lot of manpower and material resources in this way, and build so many earthen blast furnaces at once for testing.

So after tossing for a while, Yu Xiaotian finally determined that these two small clay blast furnaces can indeed make molten steel, although he can't carry out metallographic inspection for the time being, but he can still use some soil methods to carry out some simple tests on these products.

In the end, after testing, some of these strip steels produced initially belong to low-carbon steel, some of them belong to medium-carbon steel, and of course, some are high-carbon steel, which can finally be used, although they can't all be used to make muskets, but this thing can't be thrown away.

Therefore, he ordered to dismantle all the earthen blast furnaces that had partially failed the complete experiment, and after slag removal of several promising blast furnaces, they were adjusted, and the structure of the two small earth blast furnaces that had been successfully tested was re-enlarged, and several slightly larger earth blast furnaces were rebuilt to start steelmaking production.

Although the quality of the steel produced by these soil blast furnaces fluctuates very much each time, but after all, the molten steel is still smelted, and the next step depends on the gradual exploration of the experience of these craftsmen, Yu Xiaotian asked the craftsmen in the steelmaking plant to develop a set of strict operating systems and specifications, and carry out production operations in accordance with the specifications.

Because this thing is definitely a high-risk industry, a little poor operation, it may blow up the furnace or fire and other serious accidents, dead people are a common thing, just started production, when the molten steel was released again, there was an accident of molten steel splashing and injuring people, two workers were burned on the spot and were seriously injured, and they swallowed their breath before they 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 the feeding, and check the discharging situation, and finally gradually explore a set of more practical methods to ensure that the quality fluctuation of the steel is reduced.

Although the steelmaking thing is a twist and turn, but in the end it is still steel, people will not remember those failed things, they are most concerned about the success of steeling, when these craftsmen see these unsightly clay blast furnaces, there is really a can make molten steel, so suddenly there is a jubilation.

Although this kind of soil blast furnace does not look good, there are often problems, and the quality of the molten steel is unstable, but after all, it is still steeled, and each furnace can produce thousands of catties of molten steel at a time, which is much more than they used to use the frying steel method and the steel filling method to make a little steel at a time.

After having these steels, it can make Blacksmith Zhang happy, and for a long time, Blacksmith Zhang has also had a headache for the quality of the barrel of the wolf's tooth rifle produced by the gun.

Because the barrel is made of wrought iron, after the rifling is pulled out, a barrel can not shoot dozens of bullets, and the rifling will soon be worn bald, so that it can only be removed and replaced with a new barrel, and the old barrel is transported back to the gun for either re-rifling, or simply returned to the furnace for reconstruction, which is a serious waste.

In the past, he had also used some craftsmen to use the steel smelted by frying steel and filling steel to create a small number of barrels, and after drawing rifling, after trial, the life of the rifling of the barrel was at least two times or even five times longer than that of the barrel made of wrought iron, eliminating the trouble of replacing the barrel frequently.

However, the quality of the steel refined by that method is not guaranteed, and the quantity is really low and unacceptable, and it is impossible to greatly replace wrought iron to make a barrel, and it can only be used in a very small amount and equipped for special combat teams or snipers.

Now that Yu Xiaotian has finally figured out a way to produce steel in "large quantities", then the next step can be used to replace wrought iron to make barrels, and the number of wolf tooth rifles produced by guns will increase day by day, and gradually those South Japanese flintlock pistols can be replaced and become the main combat equipment of the sea wolf.

You must know that because the production quantity of wolf tooth rifles has not been high, and a large number of spare barrels have to be produced, which can be replaced at any time as spare parts, the army of the sea wolf is anxious to scream, not to mention the navy that has not been able to equip the wolf tooth rifle.

The navy now also has a naval company, to garrison the battery and cooperate with the navy to carry out operations, they have been unable to obtain the wolf's tooth rifle for such a long time, so the navy people are also full of complaints, to Yu Xiaotian to complain and get no consent, so they often go to harass the guns in private, complaining that their production is too low.

The people in charge of the guns are now harassed by these guys and hide when they see them, and now with steel, this problem can be alleviated a lot.

As a result, some of the limited steel that had just been produced, after inspection, the steel that could barely be supplied for guns was immediately snatched up by guns and began to be put into production.

It is a pity that the current output of the soil blast furnace is still very low, far from meeting their needs, and can only wait for the new soil blast furnace to be gradually put into operation, and the steel output can gradually climb up This problem can be solved.

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

In fact, bearings and gears are not difficult, a little through the thing, but want to produce, but it is not a very simple thing, to solve the technical problems, there are really a lot, but also to find a way to manufacture some machines to produce, the inner and outer jacket of the bearing to be quite precise, do not use the boring machine and lathe with higher precision.

If you expect to use craftsmen to make it by hand, then even if it can be produced, the cost will be high and the quality will definitely not be good, so if you want to develop such a seemingly simple thing, you must first overcome one obstacle after another.

However, Yu Xiaotian is not very anxious, this kind of thing has to be gradual, after a breakthrough, with the work machine being developed, in order to produce a machine tool with high precision, everything has to be done slowly, it is impossible to eat a fat man in one bite.

Just when the steel smelting in Tamsui City was in full swing, the things on the side of the port were also advancing steadily, and the sea wolf invested nearly 10,000 manpower in the port in two or three months, as well as countless materials, so that the work over there went relatively smoothly.

With Ma Tiancheng, a ruthless guy sitting over there, even if these laborers were dissatisfied, at first, after making some trouble, they saw that Ma Tiancheng used thunderous means to kill him immediately, and the rest of the messy laborers didn't dare to come nonsense.

Therefore, the construction of the Dagou Port Wharf, it took only three months, it was basically completed, and now the Dagou Port Wharf has built six trestle bridges deep into the sea, which can be used for more than a dozen ships to berth at the same time to load and unload goods, which has greatly increased the material throughput capacity of the Dagou Port.

As for the local indigenous tribes, when the sea wolves first began to land, they did not see too many sea wolves, and they repeatedly attacked the area around the docks and the camp in an attempt to drive these outsiders away from the port of dog-fighting.
