When Williams. In the telegram, when I got this plan, it was already 2 days after American time, by the way, there was a batch of iron ore samples, this was not Yang Yuanzhao had already prepared, it was Harpy who helped to complete, came back from the United States, said that when he came to Williams, Yang Yuanzhao mentioned a plan for the steel mill, of course, just casually mentioned, saying that Williams may be used in the future, Harpy was interested, and directly collected China's iron ore, and at present, several of China's largest iron mines have been collected, of course, It also includes Baiyun Obo, which is the closest to Baotou.

Baiyun Obo mineral deposits, at this time is still buried in a grassland, but only afraid of people, among the engineers who came to Baotou, two happened to work in the steel plant, Harpy took the opportunity to transfer them on a business trip, 150 kilometers away Baiyun Obo, found this piece of open-pit metal mine, the two engineers were stunned on the spot, if not in poor and backward China, if such an open-pit metal deposit is found in the United States, no matter what the taste of the mine is, it can definitely send them to the throne of millionaires.

It's a pity that all the results are from the German and American companies, and they discovered this piece of metal ore under the assignment of the German and American companies.

This discovery also gave Harpy a new view of Yang Yuanzhao, Yang Yuanzhao definitely had far-reaching plans, this piece of iron ore is probably the location of the steel plant, so he selected iron ore from all aspects, and then sent it to the United States, ready to find time, let Williams's real room, conduct a test, and by the way, give a construction plan.

Unexpectedly, such a move was actually crooked, when Yang Yuanzhao's telegram came, just Harpy's letter and ore, after more than a month of drifting across the ocean, arrived in the United States, the staff of the American German and American company, taking advantage of the situation, formed a plan for the ore and specific requirements, and handed it over to Williams's room.

At this time, Williams is still looking for possible investors for the tens of millions of tons of steel plants, whether it is the American chaebol or other foreign forces, they have all been found, even if everyone recognizes his profession and invests hundreds of millions of dollars, no one has spit out, after all, the current 100 million dollars is still a huge number that is unimaginable to anyone, and there are very few real money that can be taken out.

When Williams received the German-American company plan, he had almost forgotten about the small German company, but the person responsible for delivering the plan, he was very familiar with it, in the past six months or so, Williams was able to run smoothly, thanks to him, in addition to providing more than $100,000 in scholarships in the school, he also helped Williams to introduce a lot of business.

Keeping in touch with Williams's room was a plan made by Harpy before he left, and the person in charge did a good job of achieving this, so when he handed over the plan, Williams didn't reject the small project. 150 tons of steelmaking furnace is not small, but it is not the largest, in his steelmaking plant plan, it has been 200 tons, or even 300 tons of huge steelmaking furnace, 150 tons, really not very big.

I thought it was a very simple 150-ton steelmaking furnace, but after reading all the articles, Williams became interested, because this above requirement was very special, and it seemed to specifically mention the application of oxygen.

Oxygen is an oxidizing agent, any combustion reaction is an oxidation reaction, the combustion of added oxygen will be a lot more violent, adding oxygen to the steelmaking furnace, it has been repeatedly mentioned, but the addition of oxygen is not easy in the burning steelmaking furnace, it is not a waste in vain, or the effect is not strong.

In the proposal of the German and American company, there are two methods, one is to add the accelerant to generate oxygen, which can be added together with the raw materials, which is easier to control, as long as the accelerant that does not have much impact on steelmaking, this is also the past, the method of oxygen addition is proposed, this method, the probability of overall improvement is not high, after all, to ensure the effect of molten steel, the formula is extremely strict, and there are few formulas that do not have an impact on steel, even if there are multiple choices, The most effect is only to increase by 10, in steelmaking, such an effect, is not a lot, the investment is huge, is a kind of transformation that outweighs the loss.

What really makes Williams tempted is a proposal later, oxygen blowing the top, which is a proposal that no one has ever thought of, before, the most is to choose ventilation, add enough air, so that coking coal or coke, get better combustion, but if it is filled with oxygen, the bottom is not easy to infusion, which will affect the molten steel, and even leakage, but the top is a method.

Boiling molten steel, a certain degree dù above, just like a pot of liquid, from just converting the liquid, to all conversion, the reaction is complete, it takes 6-7 hours, this is also the efficiency of steel production, generally a steelmaking furnace, when running at full capacity, a day is 3-4 furnaces of steel, so, 150 tons of steelmaking furnace, the daily output is about 900 tons.

However, if it is oxygen blowing the top, in the steelmaking furnace, the mixture between oxygen and fuel is not sufficient, many dyes are not burned completely, and the removal of carbon several times is also a key point of steelmaking, reducing carbon, and can not be all reduced, which is a key to steelmaking quality control, but on the top of a steelmaking furnace like boiling water, it is easy to fuse oxygen into the molten steel with the method of oxygen blowing, so that there is no reaction of carbon in the molten steel, and other dyes are burned quickly, effectively increasing the temperature in the furnace.

This seems to make some sense, Williams's real room, there is a small steelmaking furnace, the real room generates oxygen and the like, all of which are convenient, simulating the environment of steelmaking, after using oxygen to blow the roof, I found that the efficiency has been greatly improved.

Because there is no suitable high-temperature thermometer now, it is impossible to control the temperature in the steelmaking furnace, Williams and the researchers, relying on estimates, finally came up with a more successful steel, which can reduce the subsequent steps of steelmaking, after the oxygen blows, the carbon content of the steel is significantly reduced, as long as the control is done properly, there will be less than the next two steps, although the steelmaking plant, the key is the number of steelmaking furnaces, but it is finally improved efficiency.

The latter improvement is directly aimed at the steelmaking furnace, because the oxygen blows the top, the temperature in the furnace is raised, and on the whole, the steelmaking time has been reduced from the original 6-7 hours to 5-6 hours, and the steel furnace in a day has increased from less than 4 times to 4.5 times, or even more, and the daily output of steel has increased by about 70 tons.

Only 70 tons, but on behalf of the improvement of steelmaking efficiency, in the steelmaking equipment, in the steelmaking cost, occupy a huge part of the situation, about 10 improvements, on behalf of the cost and scale, taking the national steel mill as an example, 10 million tons of production capacity, after the transformation, maybe it will become 11 million tons, the improvement is very obvious.

I didn't expect that in China, such a constructive construction can be mentioned, which is obviously a booster, which will make the whole world's steelmaking change dramatically.

Williams doesn't know that this is only the initial effect of oxygen, his oxygen supply, is not a reasonable concentration and content, in a sense, just play the surface of the oxygen blowing top, even a very small part of the role, the real oxygen blowing top, is used on the converter, the oxygen blowing top converter, can reach the speed of 40-50 minutes a furnace, the efficiency does not know how many times higher than the open hearth, even the open hearth, after a strict oxygen blowing top transformation, scientific control of oxygen concentration, It is also possible to make the speed of a furnace reach 2 hours, or even lower, but this requires a long time of real yàn and calculation, which can not be obtained with a tap of the brain.

In any case, Williams finally took this plan seriously, it looks inconspicuous, there are only 6 150-ton steel-making furnaces, and the daily output is only 3600 tons, plus the oxygen blowing roof, it may reach about 4000 tons, and the annual output of the steelmaking plant does not exceed 1.5 million tons, which is not a big design, and cannot be called large. But it is also a meaningful addition. Not to mention. Germany and the United States paid a big price. For this time the design. Gave a design fee of 500,000 US dollars, which is on a steelmaking furnace of this scale, the design fee is already very high, for the merger and operation of the national steel plant, he Williams personally participated in more than 3 years, spent a lot of energy, and finally obtained, but less than 2 million US dollars, this small steelmaking plant, just let him design, did not let him personally go to the construction and construction, gave 500,000 US dollars, Germany and the United States is really wealthy.

What Williams values the most, as long as the plan of these 6 steelmaking furnaces is perfectly implemented, next, there will be a follow-up second phase, the second phase of 20 150-ton steelmaking furnaces, and the third phase of 30, a total of 56 steelmaking furnaces of the huge steel group, this is the biggest business, if it can really reach 56, it means that the total steelmaking tonnage of this steelmaking plant will exceed 12 million tons, which seems to be in another sense, built what he expected, $100 million invested in a steel mill.

Of course, Williams, not a hairy boy who has no knowledge, a 150-ton steelmaking furnace, at least more than 2 million US dollars, plus the transformation of the oxygen blowing roof, the addition of some chemical equipment, the total investment may reach 2.5 million US dollars, 6 15 million US dollars, maybe someone invested, but 56, it is almost impossible for anyone to invest, according to the profit ratio of steelmaking, it can be completed in 30 years, it is already lucky that he can not be lucky, so, he just put his mind here, And didn't think about it, the follow-up projects, those are a little far away from him.
