Chapter 139 Electric Furnace
Gritting their teeth and getting into the electric furnace project, the people who traveled through had no choice.

The reason is simple: there is no coal.

If there is no coal, there will be no coke, and equipment such as open hearth converters will not be used.

There is coal in Taipei, but it rains 200 days a year on that piece of land. It is necessary to open up wasteland and dig coal in the jungle of Taipei in the 17th century. How many people are going to die to open the road and fill the pit?What's more, we must drive away the Spaniards first, build a transport fleet, and divide the bases.
There is no need to consider the coal mines in Taipei. Even if coal is obtained from Guangdong and Vietnam, it is far more reliable than Taipei, which seems very close.But right now a certain force has no extra resources to go south at all: Zheng Zhilong of Xiamen and the surrounding pirates, the Portuguese of Macau and the surrounding pirates, these numerous hostile forces have blocked the passage of all the people going south.

Coal, a cheap bulk commodity, can only be obtained in small quantities now, and there is simply no extra transportation capacity in the traveler to pull this thing.

Therefore, the electric furnace steel project became the only choice for the time travelers.

The power resources in the kiln area have great potential, especially after importing a batch of lithium battery electric saws, the logging efficiency has greatly increased, and the leftovers produced by the wood factory alone cannot be used up every day. This time, the 3-ton small electric furnace project So get on the horse, because the current power resources are abundant.

However, it is not so easy to take advantage of resources.

At the beginning, the kiln base had only one generator, which was a small 6000KW Siemens steam turbine.This set of generators is enough to cover all the existing power projects including wood factory, brick kiln, small farm machinery and lighting.

However, once the electric stove came, it would not work.

After a 3-ton small electric furnace is started, it must account for at least one-third of the power generation.This is not the main thing, because the principle of the electric furnace is to generate high temperature by short circuiting the positive and negative poles, so the voltage of the electric furnace will fluctuate and flicker during the smelting process.

As long as the electric furnace is turned on, the harsh environment where the current changes drastically in an instant, the thin power grid in the kiln area will probably kneel on the spot, so it is a prerequisite to build a special circuit system for the steel mill, which is why a The reason why 3 tons of small electric furnace can use 5 boxes of import quota: the equipment other than the electric furnace takes up too much space, especially the electric equipment, and the future development should be considered, so it must be in place at one time. The transformers are large. Leave enough margin.

The small round electric furnace is a specially purchased product of the Swedish General Company, with a diameter of no more and no less, 2.8 meters.The electric furnace looks small in size, but there are many attached equipment: smoke hood smoke pipe, water cooling cable, furnace cover lifting equipment, trolley, slag barrel, hydraulic cylinder, hydraulic control system
The above is just the furnace part.There is also a new set of steam turbine system for power generation, supporting high-voltage power supply system, rectifier, transformer, and low-voltage console, various control boxes, and never too many cables
Testing equipment: direct reading spectrum, fluorescence instrument, sulfur carbon analyzer, grinding machine, etc.

There are 5 boxes of these devices, and after that, another box of consumables such as high-power graphite electrodes will be added.
One of the earliest brick kilns in the kiln area has been demolished.This kiln is an emergency product. It is an old-fashioned trapezoidal kiln that can only produce one furnace of bricks at a time. Later, as the power plant started, the brick making machine began to produce a steady stream of bricks, and this old kiln could not keep up with the rhythm soon. .

So Chuanzhong re-selected the site, and built a large-area wheel kiln in the downstream of the kiln area. The main body of the wheel kiln is made of basalt and red bricks, and the refractory bricks are self-produced magnesia bricks.

Magnesia bricks are a by-product of cooking salt, yes, cooking salt.In the beginning, the salt bought by the people in Transit was bought in Hangzhou. After the power plant in the kiln area was put into operation, they used the waste heat from the power plant to build a few ponds to cook the salt with seawater. It was a little low, but the product was good, and even the locals said it was good.

After the lime kiln is built, concentrated seawater + lime milk is used to extract magnesium hydroxide, and then heated to extract magnesium oxide. Magnesia bricks are made in this way.

With the new brick kiln, the original old kiln and the supporting small brick yard became the natural location of the new steel factory.Now the old kiln has long disappeared, replaced by a brick-concrete structure with a crane on the top and slide rails under the feet, a large workshop with a height of 5 meters.

A set of silver-white, shining electric furnace system has stood in the middle of the workshop.Above the circular furnace body is a metal cross arm, which is responsible for the graphite electrode clamping system; behind it are power equipment such as rectifiers and transformers connected by cables.

The electric furnace system with a strong post-modern industrial style is indeed a bit sci-fi: various silver-white metal boxes and electric furnaces are connected by silver-white water-cooled cables in the middle, just like the beard of some kind of metal octopus monster, which is a bit weird.

In the eyes of the bright furnace workers in the workshop, the set of iron objects that the masters took half a month to build is not like an iron furnace, but like a monster.

However, in the eyes of the industrial people in the workshop, this electric furnace is an out-and-out treasure, a sexy lady exuding industrial beauty.

Naturally, it is not ordinary people who can manipulate young ladies.

Chen Jingtai, 33 years old, thin and capable, former manager of Yonghengli Metal Processing Company.The company specializes in producing all kinds of ground strip steel, accepting various orders, and processing profiles. Today he stands here, and he is definitely a professional counterpart.

But Chen Jingtai knew very well that if he dared to use this Swedish electric furnace to smelt a furnace of ground steel for everyone today, he would definitely be thrown into the furnace while it was hot. There are no police in this ghost place!

To put it bluntly, the Yongli Company founded by Manager Chen was a small private processing factory, specializing in providing low-quality steel strips to the market.The quality of Eternal Lee’s ground strip steel is still good. Others’ steel ingots will break when dropped from a height of one meter, while Eternal Lee’s steel ingots will only break after three meters, so they are more confusing and often get away with it.

Whenever the rumors from above got tighter, Chen Jingtai would close the store and close the business, and reopened after the rumors passed, and the small life was very enjoyable, until the regulation storm came and Manager Chen was destroyed by the joint investigation team.

Now in the 17th century, Comrade Chen Jingtai actually saw a complete set of electric furnace system produced in Sweden in such a barren land, and then looked at the furnace laboratory full of equipment in the corner of the workshop. I can't help but feel a little embarrassed.

You know, in his factory back then, apart from the two intermediate frequency furnaces, the rest were ground ditches and scrap steel, not to mention laboratory equipment, even the intermediate frequency furnaces were portable, the kind that could be loaded onto a truck before a major inspection. .

Alas, recalling the glorious past, Chen Jingtai came back to his senses after sighing lightly, looked at his watch, then stepped forward, drove all the cross-travelers who came to visit in the workshop to a safe place, and ordered everyone to wear protective masks. eyepiece.After that, he personally checked the furnace material and all the power links that had been piled up already, and greeted the cross-border people and Ming furnace workers from several steel factories to check their full-body protective equipment.

Chen Jingtai has to be careful. The full name of the electric furnace in front of him is "3-ton DC electric arc furnace". It is not the gentle intermediate frequency furnace in his factory; Human life, so have to be careful.
