Alien Lord

　　As for the iron-making shops on the mainland of Shenzhou, hehe, it is directly the bellows.

　　 There are two types of bellows, one is like an accordion, with wooden boards up and down, folded leather around it, and it is used to step on the blast, and the other is a large wooden box with a valve and a push-pull blast.

The first type of bellows has been used for a long time, and the leather will be aged. Lin Ze is afraid that it will be too late to replace it, resulting in the final blowout of the blast furnace without sufficient air supply. If that is the case, the hot molten iron in the blast furnace will flow out instantly. The workers nearby became coke.

Because of this, Linze should not be installed well for this kind of bellows, which is too dangerous, so in the end, Linze decided to install a valve push-pull insurance on the blast furnace side, and use the animal power of the fire armor to provide sufficient power, and then use eccentricity The power of the wheel turns the previous rotary motion directly into reciprocating motion.

　　 Of course, these modified Lin Ze are just based on the Xuanke, and they are all based on the records in the book. The real refining, installation, and debugging are all done by Hu Yan, the master of refining.

　　 In this way, four wind boxes and four air ducts were arranged around the entire blast furnace, and several spare wind boxes were made to prevent accidents.

In addition, the last section of the blast furnace inlet before entering the furnace is directly merged. There is a fire pond isolated from the inlet, containing coal-burning. In this case, the outside air will be trapped before entering the furnace The coal here is heated to 800 to 1,000 degrees, which is actually the air preheating technology.

　　Air preheating is the most critical step to improve the efficiency of ironmaking in modern steel production. In Lin Ze’s impression, at least in countries around the world before China’s Qing dynasty, no one could master this technology.

　　 This is the same in mainland China. The society here is even more backward, let alone mastering such technology.

　　 Outside the huge blast furnace body, Hu Yan also built some supporting points with solid wood, which are actually some independent maintenance towers that fell on the ground. In order to facilitate labor saving, Hu Yan formed the feed system on the furnace roof with chutes, pulleys and pulley sets.

The molten iron produced by the blast furnace is pig iron with a high carbon content and many impurities, but it can already be used to cast large iron parts, such as iron anchors, anvils, etc., so Hu Yan added a groove to the iron outlet. It is usually closed and opened directly if necessary. Afterwards, the red hot metal will be directly injected into the outer mold through this side, and finally large iron parts can be cast.

　　Hu Yan also built a large iron-fired stove next to the blast furnace. In fact, the shape of this iron-fired stove is a bit like a teacup of kung fu tea. It is a reverberatory furnace type separated by flame and iron. It is also built with refractory bricks, the bottom of the hearth is sunken in the middle, surrounded by an arched furnace wall, the lower part is the combustion chamber, and the air inlet is at the bottom of the combustion chamber.

　　 Its current structure can be seen as a three-story building, with the third and second floors separated from each other, and between the first and second floors are a number of movable iron fences.

At the beginning of use, the molten iron flows directly from the blast furnace to the third floor. At this time, the coal on the second floor is lying on the iron fence and is burning, continuously heating the molten iron upstairs. After the coal is burned, you can simply flip the iron At the fence, the char on the top fell into the de-slag room on the first floor.

　　 After the iron fence is laid flat, coal can be added to it from a 45-degree inclined coal inlet, and then continue to burn, just repeating this way until the end of this time iron making.

　　 is also animal power blast, but here, unlike the blast furnace over there, a tall chimney is also built on the side.

Because of the lack of electric power facilities, even the steelmaking plant Lin Ze established now still uses human power to stir the iron furnace, there is always a strong man by the furnace, which is made of cooked iron Stir fry iron rods, stir back and forth with sweat.

However, in the end, Lin Ze found that the effect of doing so was still too low. Lin Ze, who understands the powerful capabilities of modern machinery, obviously will not let workers do this kind of work that is both tiring and will seriously damage his own health. Therefore, he let Hu Yan made a bracket on the top of the furnace. A large round roller was hung in the middle. There were three wrought iron sticks extending obliquely towards the hearth. The fire armor was still providing power, so there was a simple, However, extremely practical mechanized iron-fired equipment.

In the past, pig iron was cooled into ingots and then heated to smelt mature iron; now Lin Ze uses the technology of directly frying the pig iron from the blast furnace to mature iron. This technology, even on the earth, was originally intended to be The methods that did not appear until the Ming Dynasty, like Song Yingxing of the Ming Dynasty, are recorded in "Tian Gong Kai Wu".

　　 However, these technologies are now directly used by Lin Ze.

　　 is far worse than modern technology, but it is just right for Lin Ze.

Once the pig iron is refined into mature iron, it can be directly poured to make farm tools such as **** and shovel. Of course, the production process also requires continuous forging, carburizing and quenching by the blacksmith. The wrought iron is soft, strong forgeability, and processing Superior performance.

There are a lot of steel mills and so on, so Hu Yan directly built a dozen of forging furnaces lined up side by side. The basic structure of this thing is nothing like the forging furnaces for all rural blacksmiths to repair farm tools such as **** iron shovel. The difference is to increase and thicken.

　　Enlargement is for forging large iron parts later, and thickening is for heat preservation. After all, it is used for a long time. Such a design can also save fuel.

　　 Needless to say, the animal power of Huojia cattle is still used here. Of course, compared with the blast furnace and the iron stove, these are the grandsons of the grandchildren.

Not only that, Lin Ze and Hu Yan filmed a simple animal-powered forging hammer next to each forging furnace, under the forging hammer was a thick anvil, under which was a thick oak stem, and then Below is the base of cement and stone casting. Such a multi-layer composite force-bearing structure can withstand the huge impact force of the forging hammer falling.

　　 These forging hammers, those large forging hammers weigh three hundred pounds, stroke three feet, and drop about 50 times per minute; the small ones weigh seven to eighty pounds, stroke two feet, and drop about 150 times per minute. The large forging hammer is used for roughing, and the small forging hammer is used for finishing.

In fact, with the current technical ability, this finishing process can't be refined. After all, it is still hammered. After all, the processing technology of such a rough animal forging hammer is actually used by the blacksmiths in the blacksmith shop. There is not much difference at all when one hand strikes one hammer at a time. If there is a difference, the efficiency is only many times higher.

　　After all, manpower is limited, and the side of the fire armor can always output animal power.

　　Unfortunately, the current technical conditions can not be stamped, let alone precision forged, otherwise Lin Ze really can have metal machine tools available.

　　 Of course, if Lin Ze let Hu Yan study with all their heart, it really could be realized, but finally Lin Ze thought or gave up.

　　 It doesn't matter if you are one step ahead. If you really are a dozen steps ahead, others will treat you as a monster. At that time, there may not be a place for Lin Ze on the entire Shenzhou continent.

　　Think about it, if all the sect, Yuan infant masters, and even the stronger come to Lin Ze for trouble, will Lin Ze still have a way to go? !

Blast furnaces, blowers, animal power forging, iron-fired furnaces, these things are still in the ordinary people's cognition, but if you really want to take out more modern machine tools, I believe that even if you are a smelter like Hu Yan, it will be the same Misty, if that's the case, then I really don't know what will happen.

Lin Ze burned a lot of large clay pots with high-alumina clay. These things were easy to make. Lin Ze soon found a few people who had previously dried in porcelain kilns to do this kind of thing. For these veterans, It's so easy, these people took the task without hesitation.

It is also very simple to make, that is, first crush the clay, add water and sieve it into fine mud, then shape it by hand on a rapidly rotating wooden plate like a plastic tire, and finally burn it in a special high-temperature kiln for 10 hours The pan is freshly baked.

　　 At the beginning, many people did not understand, like Xu Sheng's misty water, can these clay pots be used to make steel? That's not like cooking.

　　 Actually Xu Sheng was right, these are what Lin Ze used to fry steel.

　　An ancient steel-making technology, said that there are mainly three processes of steel frying, hundred steel-making and steel pouring.

　　Steel frying is actually iron frying. The iron frying furnace designed by Lin Ze can be produced. In fact, the main products are wrought iron, and a small amount of medium and low carbon steel. The quality is very unstable;

Hundred Steel is made of fried steel as the raw material, repeatedly folded and forged after heating, or repeatedly forged with several raw materials with different compositions. The process is complicated and costly~www.wuxiaspot.com~ is only suitable for making some treasure knives Sword, the cost and price are not low;

As for the steel pouring method and the like, there is a very detailed record in the "Mengxi Bi Tan": "The so-called iron wrought iron in the world uses soft iron to bend the disk, and the pig iron is trapped in the middle and sealed with mud. Forging order Joining, so-called group steel, also known as pouring steel.

　　 These three processes are not bad, but they are not suitable for large-scale industrial production.

　　 This time Lin Ze wants to make it, actually it is crucible steel.

Speaking of this crucible steel, it was actually invented a long time ago, or invented in the spring and autumn. Since the invention of this crucible steelmaking method, it was the most prosperous in the Han Dynasty. It used the steel it made to make a strong fish scale armor, The sharp first sword, only the invincible Han army, and the glorious victory of the Huns from the Mongolian // ancient / / plateau to Europe /// Chau, only the "criminal Han, although "It will be far away"

Maybe it was the Wuhuranhua War, maybe it was some other inexplicable reason. The crucible method was lost during the Northern and Southern Dynasties. Instead, the walls were scented outside the walls and developed in other countries. Zi Gang, the weapons made like swords//swords are extremely sharp, and they have cut off the heads of countless crosses//armies.

　　Blast furnaces, waterwheels, iron stoves, workers' dormitories, and cooling water towers were all built one by one. Now it can be said that everything is ready, but the wind is owed.
