my magic industry

Chapter 82 Steel
After about three to ten minutes passed, Xia Lin asked someone to open the furnace door with an iron braze, and took a closer look at the condition of the molten material inside, and found that the melting condition of the furnace material was not bad.

He asked the workers to go up the aisle to use a special clip to remove the magic crystal to stop the discharge heating, and then started the second feeding and pounding the furnace.

I also began to explain to the three dwarf masters how to observe the melting of the furnace charge and how to deal with various abnormal situations. Since this knowledge is also very similar to the experience accumulated by the dwarves during smelting, these few dwarves The dwarf master can even draw inferences from one instance.

There are special recording personnel on the side to record these key points and various data, which will be used as a reference by other furnace managers in the future to improve the quality of EAF smelting.

The edge of the electric arc furnace has a high temperature of at least 500 degrees Celsius. These workers are sweating profusely under such high temperature. The molten furnace charge is more difficult to stir than the ore pile in the exercise.

However, within a minute, the leader of the stove making team had to ask the next worker to go up and replace them. The wet towels and masks of the workers who came down had become dry, leaving only a little bit of sweat soaked just now.

"Okay, it should be almost done! Restart the furnace!"

Xia Lin saw that the slag from the furnace material was not bad, so he asked the workers to close the furnace door again, inlaid the magic crystal on the rune plate, and restarted the heating.

After more than ten minutes, Xia Lin finally announced that the slag had started, and the staff next to him picked up the iron rod and pried open the furnace door again.

Several workers went to the side of the electric arc furnace and started the hydraulically driven winch, and lifted the electric arc furnace body weighing six to seven tons through iron cables little by little. When the winch was in place, the slag was dumped out.

Since there is no deoxidizer, Xia Lin can only ask people to sprinkle some carbon powder into the charge during the reduction period to protect the molten steel from absorbing too much oxygen during the reduction period, which will cause the quality of the steel to decline.

After waiting for another 10 minutes or so, Xia Lin finally announced that steel tapping could start. Five steel water tanks with different specifications but with a thickness of more than 20cm were transported to the front of the furnace.

Following Xia Lin's order, 15 workers in the two groups began to turn the ratchet winch, and the hot molten steel flowed along the opened tapping trough to the cast iron shell and the refractory brick-lined steel trough, emitting an astonishingly high heat.

After five times of dumping, all the molten steel in the furnace entered the molten steel tank and began to cool.

"Success!?"

After pouring all the molten steel out of the furnace, Xia Lin took the three dwarf masters to look at the situation inside the electric arc furnace along the opened furnace cover, and found that everything was in good condition. Said rather inconceivably.

He was already prepared for repeated experiments. After all, even if he had the electric arc furnace drawings he had seen in his previous life as a reference, there would be a lot of differences after some real magic changes. There will be some hidden dangers leading to the failure of steelmaking.

Such a successful trial production can only be said that these magical changes made by Xia Lin did not cause much impact. The electric arc furnace body has not been changed much except for the furnace cover. According to the principle of the electric arc furnace, there is indeed no what's the problem.

Even the 5-ton furnace body is still too small, which sounds like a lot, but in fact, the volume of steel produced at one time does not even reach 1 cubic meter.

But even so, the production efficiency of the electric arc furnace has completely exploded the traditional blacksmith's hundred steelmaking or low-quality lump steel. Now it depends on the quality of this batch of steel.

After the molten steel was cooled and formed into slabs, thin slabs, and billets, Xia Lin used the spark identification method.

The spark identification method is to judge the type of steel by the shape and color of the spark generated by the high-speed friction of the grinding wheel. The bright line represents the iron component of the steel, and the spark is produced by the friction and burst of the carbon component inside the steel. More means the higher the carbon content of the steel.

After some tests, based on his own experience, Xia Lin made a judgment. The output of this furnace is all high-carbon steel. It seems that the amount of pig iron is still a bit too much, and it may also be the influence of the carbon powder sprinkled during the reduction period. .

Ask the recorder to record the conclusions he has drawn, and arrange for the steel to be transported to the machine tool factory, while Xia Lin and the three dwarf furnace managers continue to make steel.

The pig iron and wrought iron raw materials purchased by the industrial park from the market still weigh tens of thousands of pounds, so they must be digested quickly.

Not long after, Master Fine, who received the first batch of steel produced by the steel factory, and other dwarves rushed to the steel factory to watch the excitement.

"Boss, I didn't expect that you could really use this electric arc furnace to smelt steel, and it weighed more than 1000 pounds! The quality is also very good! In this way, our machine tools and the machines on the drawings will be available!"

As soon as Master Fine saw Xia Lin, he grabbed his mage robe with excitement and shouted loudly.

"That's good, don't worry, Master Fine. Now our steel plant has just started production, and it will be able to produce 7500 pounds of steel every day in the future. We can use steel to pave the road at that time!"

Xia Lin didn't care that Master Fine wrinkled his silk robe, and he was very happy to comfort him when he heard Master Fine say that the steel smelted in the electric arc furnace was of good quality.

Steel is the backbone of the industry. Xia Lin is very clear why Master Fine is so excited when he sees the large quantities of steel smelted in his factory. If there is no such steel, Xia Lin will suffer from rickets and brittle bones in his next industrialization plan.

Moreover, iron and steel is also the most critical step in the real heavy industry of the industrial park. With this, there will be future steel and iron combined industries, and even coal-iron composite industries.

Therefore, when the steel quality was tested to meet the standard, even Xia Lin couldn't restrain the joy in his heart, not to mention the dwarf masters who regard smelting and forging as their greatest hobby.

"Using steel to pave the road? How much steel will be consumed, how can it be realized? You must be lying to me!"

Master Fine heard Xia Lin's new cake, although he was still immersed in excitement, he still shook his head in disbelief.

"Of course it is possible. After the production of equipment in each factory is completed, I plan to use the steel produced by the steelmaking plant to build a railway from the wharf to each factory in the industrial park. Of course, due to limited production capacity, these railways are temporarily closed. It will only be wood clad steel.

At that time, the unloading of ships that come to transport raw materials every day can be directly loaded onto the flatbed trucks running on the railway, and the flatbed trucks can move forward along the railway by manually pedaling a chain gear disc rotating device.

In this way, those raw materials can be sent to the warehouses of various factories conveniently, quickly and easily! "

Xia Lin looked at the electric arc furnace that was smelting steel, and a smile appeared on the corner of his mouth, describing the scene after the railway for Master Fine and the surrounding employees.

With the expansion of the production scale of the industrial park, more than 100 people are required to carry the horse-drawn carriages and employees to carry the raw materials every morning. If there is such a railway, it will undoubtedly greatly improve efficiency and reduce labor costs.

"It sounds like it is feasible, then you have to build this railway as soon as possible!"

Master Fine imagined the wood-clad steel road that Xia Lin mentioned, and felt that it was indeed possible to realize it, so he said excitedly to Xia Lin.

"Don't worry! Sooner or later there will be!"

Xia Lin also nodded with a smile. With the electric arc furnace, a weapon beyond the times, 25 tons of steel can be produced a day, and almost [-] tons of steel a year.

Even if it is to build a real railway, it is enough for a whole hundred kilometers.

Magic is really a good thing. It can help me overcome technical obstacles so easily, and I don’t know how many years ahead of time to come up with the electric arc furnace.

The three-day trial production was completed, during which there were many problems in the electric arc furnace. After Xia Lin solved them one by one, the trial production was officially ended, and it was announced that each of the 1 employees in the steelmaking plant would be given [-] gold Lunt bonus.

Amidst the cheers of these employees, Xia Lin asked the three dwarf masters who had gradually started to take turns to be the furnace chiefs in charge of the production of the electric arc furnace, while he came to the machine tool factory.
