The time soon came to 4 p.m. Wang Bin wanted the workers to get off work first, but he wanted to think about which link was wrong, which led to so many smelting failures today.

    But the workers wanted to try again, because the hearts of the workers were actually worse than those of Wang Bin, because Wang Bin asked them to come here to produce special steel, not to waste materials.

    The workers are also well aware that the price of these materials wasted today alone is at least hundreds of thousands, because the price of raw materials for smelting these special steels is not cheap, and even some materials in these special steels, even if they have money, may not be available.

    Seeing the situation of the workers, Wang Bin agreed to their request. In fact, Wang Bin doesn''t care much about these wasted materials. Even if these materials are worth hundreds of thousands, so long as they can smelt the special bearing steel, they can earn back the money soon.

    Of course, Wang Bin has no expectations for the last furnace of special bearing steel smelted today. There are too many failures today.

    However, after the last furnace of special bearing steel was smelted, it was unexpectedly successful, and its performance fully met the requirements of the data.

    When this furnace of special bearing steel succeeded, Wang Bin''s heart was relieved. The continuous failure all day not only put great pressure on the workers, but also Wang Bin''s heart was not relaxed.

    "OK! It''s almost time. Let''s get off work first! Today''s situation must be not easy for everyone. Now that it has been successful, let''s go back and think about it." after testing the last furnace of special bearing steel, Wang Bin said to the workers.

    As Wang Bin finished, the workers present nodded one after another and were ready to go back. Due to the delay of the last furnace, it was more than 8 p.m. at this time, and these workers were the same as Wang Bin, but they didn''t even eat dinner!

    Seeing the workers walking out of the workshop one after another, Wang Bin did not follow these workers out of the workshop, but came to the laboratory. Like Wang Bin, Professor Hu and others in the laboratory had not finished work at this time.

    "Professor Hu! How are the sub projects of the new bearing steel project now, and what achievements have been made?" when he came to the laboratory, Wang Bin found Professor Hu and asked him.

    "Mr. Wang, the project you gave us before, that is, the improvement project of bearing steel, we have three projects in progress, namely, the project of improving the overall performance of bearing, the project of optimizing formula, and the project of no scarce materials.

    Among them, the project of improving the overall performance of bearing steel and the project of formula optimization have not made much progress so far, but the third project is progressing very smoothly. We have redesigned its formula on the basis of the original bearing steel technology and successfully smelted a new bearing steel.

    Although the comprehensive performance of this bearing steel is far from reaching the performance of the original model of bearing steel, the good thing is that the comprehensive performance of this bearing steel is also very advanced, which has exceeded the best bearing steel level in the civil market, and the prospect is very huge. In the future, it can maintain good performance whether for vehicle, marine or industrial use.

    Most importantly, the technical difficulty of smelting this bearing steel is also much lower, and the cost is much lower than that of the bearing steel we are producing, which is only relative to the smelting level of ordinary special bearing steel in the market, "Professor Hu said.

    After listening to this, Wang Bin nodded and was very happy. Although it was said that the smelting process of special steel was not smooth today, and many smelting failures occurred one after another, wasting a lot of materials.

    However, two special materials have been harvested. Although the previous one was only smelted by accident, and a lot of experiments are needed to become a real special steel, with samples and formulas, it is much easier to develop, at least with samples.

    After chatting with Professor Hu for a while, Wang Bin went out of the laboratory and prepared to go home. After Wang Bin left, Professor Hu and others were also ready to get off work. At this time, it was more than 9 p.m.

    At the same time, on his way home from the laboratory, Wang Bin is also thinking about the new bearing steel production line, that is, the bearing steel production line developed by Professor Hu.

    Because with the success of Professor Hu''s research and development of this bearing steel, what Wang Bin has to consider is how to produce this bearing steel. Since the research and development of this bearing steel for more than a month, Wang Bin and Tiangong technology have also invested a lot of money in it.

    In addition, the automotive glass and mobile phone glass developed by Wang Bin himself should also be produced as soon as possible. If only the experiment is successful and production is not carried out, these products will not create profits for Tiangong technology, and Tiangong technology will not be able to obtain funds for further expansion.

    However, to produce these products, it does not mean that they can be produced if they want to be produced. They must establish a production line.

    But the construction time of the production line is too long, which makes him a little impatient. Take Wang Bin''s glass production line in Tiangong technology new industrial zone. According to the current progress, it will take at least five months.

    However, Wang Bin also knows that in fact, this speed is very fast. Fortunately, Tiangong technology is in China. If it is abroad, Wang Bin can be sure that such a project cannot be completed without a few years.

    At this time, Wang Bin suddenly thought that whether it was the two kinds of glass he developed before or the bearing steel developed by Professor Hu, in fact, Tiangong technology did not have to build its own production line, because these products did not need to be kept strictly confidential like the bearing steel and special glass they are producing now.

    Because of these products, Wang Bin and Tiangong technology were originally prepared as civil products, so they can purchase ready-made factories to produce these products.

    There must be a lot of factories that can not be maintained this year, so the cost of acquisition must not be too large. Moreover, they are not very short of Tiangong technology in terms of capital, which not only saves a lot of time, but also there must be no shortage of factories acquired by employees.

    Thinking of these, Wang Bin''s mood suddenly felt a lot easier.

    Of course, Wang Bin didn''t think about this before, but before, his company had only one product, that is, special glass, and it was also a product with high confidentiality requirements, so it was impossible to operate like this.

    Now the civilian products developed have no concerns in these aspects.
