    Shen Xiufeng walked heavily towards the Iron and Steel Research Institute building.  He had a busy day doing experiments today. He had just finished his work and before he had time to change his clothes, someone from the hospital informed him to come over. He didn¡¯t know why.  The project Shen Xiufeng is responsible for is the research on direct reduced iron in tunnel kilns. This is a relatively partial topic in China, and there are not many researchers.  Direct reduced iron, as an important additive in steelmaking, actually appeared very early.  Because direct reduced iron has stable chemical composition and low impurity content, it can be used as a sustained-release agent in steel smelting when paired with scrap steel to produce high-quality steel with uniform quality. It is an indispensable and important component in high-quality special steel and alloy smelting.  With further in-depth research, it was found that in the most advanced electric furnace steelmaking, adding about 30% to 50% direct reduced iron as the charge can increase productivity by 10% to 10%.  Twenty-five; electrical energy and oxygen consumption can be reduced by more than 20%!  As a result, direct reduced iron has become an excellent raw material for smelting high-quality special steels, and the international demand for it has also increased sharply. Countries around the world have invested a lot of manpower and funds to expand the production and research of direct reduced iron.  Domestic research in this area is not late, but the results are not great.  The internationally accepted gas-based production method uses fuel oil and gas as heat sources for calcination and refining.  Due to insufficient natural gas reserves and high extraction costs in China, we cannot afford this method and can only research and explore on our own.  In view of the abundant coal resources in China, the production technology of using coal as fuel has become the consensus of all metallurgical workers.  But in actual research, everyone has great differences.  Metallurgical workers have disputes over whether to use an inverted flame kiln or a rotary kiln or a tunnel kiln to produce direct reduced iron. Everyone thinks that their own theory is more sufficient and they do not give in.  Shen Xiufeng is a supporter of tunnel kiln technology.  After more than ten years of research, the inverted flame kiln was the first to be eliminated: the energy consumption was too high, the quality could not be stable, and it could not be produced on a large scale.  The down-flame kiln has been eliminated, and the tunnel kiln has not had an easy time. However, the rotary kiln is becoming more and more popular.  Rotary kiln technology is simple and the construction cost is low. Everyone thinks that for China, a country with relatively backward technology in the world, the use of rotary kiln is very suitable.  Zhejiang, Capital City, and Shougang have all made great efforts to conduct research in this area.  But Shen Xiufeng firmly opposed rotary kiln technology.  He believes that the rotary kiln seems to have low technical difficulty and low construction cost, but the actual production cost is not economical at all!  The particularity of the rotary furnace requires space for tumbling the charge, and the space utilization rate is very low, usually less than 10%.  Using this technology to produce direct reduced iron, it is impossible to increase the output to too high to meet the growing domestic demand for direct reduced iron.  At the same time, the rotary kiln has a serious knotting phenomenon. The solidified charge will harden in the furnace body within a short period of time, and the furnace has to be shut down for overhaul, which increases production costs.  He believes that tunnel kiln technology is more suitable for national conditions.  The investment of tunnel kiln is lower than that of rotary kiln, the production cost is not as high as that of rotary kiln, and it has the potential to achieve large-scale production.  But just as he opposed the rotary kiln, more people also opposed the tunnel kiln technology.  It is believed that tunnel kiln workers have high labor intensity and need to burn a large amount of lump coal, and the cost-effectiveness ratio is too low.  Moreover, the quality is as unstable as the down-flame kiln, with huge differences between good and bad. It is also a technology that should be eliminated.  Shen Xiufeng was not convinced. He insisted on pursuing this topic. Although the hospital was not very supportive, it also allocated some funds to him to build a five-meter experimental tunnel kiln so that he could continue to conduct research in this area.  .  However, the progress of research has been very slow, especially the quality stability problem mentioned by opponents, and he has not found a solution.  Today¡¯s experiment failed again. The temperature difference between the top and bottom of the furnace was more than 100 degrees, and the quality of direct reduced iron produced in the upper and lower layers was greatly different.  If the products are not further separated and selected, they cannot be used directly for steelmaking.  "What is the reason?" While Shen Xiufeng slowly climbed the stairs, he was still thinking about what went wrong with the design of the tunnel kiln and why the temperature difference between the upper and lower parts was so huge.  "Gong Shen, who are you?" A voice interrupted his thinking. He turned around and saw that it was Gong Lu from the same hospital.  Unlike him climbing the stairs alone, there were several senior researchers with Lu Gong, all of whom were responsible for direct reduced iron-related research.  "Huh?" He was a little surprised, "Dean Shi asked me to go, are you going?" "I?Yes, it was Dean Shi who notified us!  "Several senior engineers said in unison. Everyone looked at each other and found that all the researchers working on direct reduced iron subjects in the institute were here. They guessed that they were looking for them because they were related to their research projects. "What is it?" Shen Gong  He didn't have the time to think about the tunnel kiln problem, and his mind kept thinking about Dean Shi's purpose of looking for them. The other researchers didn't care, they just wanted to report on the recent research progress, but he felt a sense of crisis in this project.  If he doesn't support it, he is doing it alone. If his superiors force him to give up the project and turn to other directions, he can't refuse. But he has been working on this project for many years and he really doesn't want to give up.  Willing to do so Maybe it would be better to give up To be honest, this topic has made him quite mentally and physically exhausted. Coal tunnel kiln technology can only be developed in China. Even the research on tunnel kilns abroad is based on natural gas, and he can't find relevant technology.  The only way to communicate with others is to look up information in the library silently, conduct technical demonstrations day and night, revise designs over and over again, and do experiments. But even though he tried his best, he still couldn't see it.  There is no hope of success, and he doesn¡¯t even know where to go next! The feeling of loneliness that no one understands and supports always echoes in his heart, and his wife often tries to persuade him, saying that he is still stubborn.  Since rotary kilns are being built all over the country, he should also do research in this area. Even if he fails, it is everyone's failure. What should one insist on? "Yeah, what should I insist on?"  It's better than the rotary kiln, but if you say it alone, no one agrees. It's just a waste of time if you insist. Shen Xiufeng felt that his body was weak, and he was holding on to the stairs to support his body. He already had a premonition of today.  The dean called everyone together. What was waiting for him might not be a good thing. He tried to calm down, but the sadness in his heart became stronger and stronger. It felt so uncomfortable to be against everyone. But he didn't want to do it anymore!  He had already said what he needed to say countless times. If he really wanted to cancel the project, he would have to accept it. "That's it" Shen Xiufeng climbed the stairs step by step, walking very slowly.  , it seems that as long as they walk slowly, the result will be different. Lu Gong and the others have already passed him and turned the corner. He is still moving forward slowly on the lower floor. No matter how long the stairs are, there is still time to finish.  , Besides, this building is not high. Standing in the conference room on the top floor, he was a little timid and did not dare to push it open. He just stood at the door in a daze, staring at the handle as the door opened.  Xiao Yan was about to come out when he was startled by him standing at the door: "Gong Shen, why don't you come in? I almost bumped into you.  " "You're tired from walking, why don't you take a rest?  "He tried his best to smile and said. "You have been busy with experiments for another day today. Come on, let me help you go in and sit down for a while.  "Xiao Yan held his arm and wanted to help him in. "No, you go and do your work.  I'll go in myself.  "Shen Xiufeng declined his kindness. "I'm fine. I'm just going to go down to find you.  Lu Gong and the others said that you were coming up, but after waiting for a while you still hadn't arrived. They were afraid that you didn't know the place, so they prepared to go down to pick you up.  "Xiao Yan smiled and helped him into the conference room. In the conference room, Gong Lu and the others were already sitting around a large conference table. When they saw him coming in, they all smiled friendly at him. Gong Li also pulled out a chair next to him.  Shen Xiufeng gestured for him to sit over. After thinking about it, he walked around to the other side and faced each other. Lu Gong and the others shook their heads helplessly, feeling helpless at his stubbornness.  , Xiao Yan went out to inform Dean Shi. After a while, Dean Shi and two strangers came in, "Gong Lu, Gong Li, Gong Qian, Gong Yu, and Gong Shen, you are all here.  Let me introduce to you that these two are Comrade Zhu Qiang and Comrade Yu Min.  "Dean Shi introduced the two strangers behind him, but only mentioned their names, not their positions or units. "They should not be from this hospital, but if they don't mention their units, it means that their work is special and they don't want to  Everyone knows. Shen Xiufeng looked much better and bowed with the others. "These are the comrades in our institute who are responsible for the research on direct reduced iron. They are experts in this field in China.  If you have any questions about this, you can ask them.?? is the most authoritative!  "Dean Shi said with a smile. "I don't dare to take it, I don't dare to take it!  " Although Lu Gong and others are engaged in scientific research, they are not ignorant of the world. They smiled and said a few words of humility. " Hello teachers, this is what we are here for today.  We accidentally obtained some information from Japan about direct reduction of iron in tunnel kilns, which is said to be the latest technology.  But we don¡¯t understand this aspect, so I would like to ask some people to help us judge whether this thing is real and whether it has value?  "The comrade named Zhu Qiang introduced the situation to them politely. Yu Min put a thick cowhide bag on the table. "It turned out to be this!" "Have you not heard that Japan is doing research in this area?  Gong Lu and Gong Li, have you heard of them?  "Yu Gong didn't think of any records in this area, so he asked Lu Gong and others. "They don't do research behind closed doors. They also need to collect a large amount of international research data. Sometimes they can't get the data.  Information can also touch them and help them get out of the maze, so everyone is still quite familiar with the latest international research progress. Even if it is tunnel kiln technology that they are not familiar with, "Is it really Japanese?"  "Gong Lu touched his bald forehead. He had no impression after thinking about it. He said doubtfully, "Japan has done research on tunnel kilns, but they use natural gas as fuel. This aspect has little significance for us to learn from.  ah!  "    "Yeah yeah!  " Several senior engineers nodded. The most painful thing about developing direct reduced iron in China is that there is no reference. We cannot afford to use what others have. If we open a new stove ourselves, we have to start from scratch, which is difficult as you can imagine.  "Let me see!  " Shen Xiufeng stretched out his hand and took the bag of information. " He also didn't believe that Japan was building a coal-fired tunnel kiln. There was no condition and no need for it! Japan can directly import crude oil and natural gas from the world, regardless of efficiency.  Isn¡¯t it nonsense that the higher-ups don¡¯t do it and instead study the coal-fired tunnel kiln? But he is the one who has the most say in the tunnel kiln. If he doesn¡¯t take a look at it, it would be too leaderless.  The others didn't fight with him, they just sat and drank tea quietly. Zhu Qiang and Yu Min looked at each other disappointedly. They had guessed this result beforehand, but they still wanted to try their luck just in case.  "As I said, the coal-fired tunnel kiln is the only one in the country.  How can Japan vigorously research this technology that we don¡¯t have?  "Yu Min complained that they shouldn't have made the trip in vain, and even let the experts from the Iron and Steel Research Institute read the joke. "You can't say that!  Zhu Qiang was also disappointed, but remained calm, "The last time Guan Fei brought a customized cement production line to the Shanghai manufacturer, the manufacturer paid great attention to it."  The drawings were sent to the Architectural Research Institute, and those experts also said that the drawings were of extremely high practical value and would be of great help to us in breaking through the 2,000-ton daily cement production line.  If there were no precedents, how could we be here?  " "I can't say that the cement production line last time was very good.  The Architectural Research Institute said that after research, they felt that this production line may be tailor-made for third world countries. The automated control equipment has been reduced as much as possible. The original drawings must be more complicated than this.  But even so, some places are beyond domestic capabilities. Small-scale production is possible, but large-volume manufacturing still requires considerable modifications combined with our own technical strength.  "Yu Min was a little unconvinced. "So, doesn't this further prove that the developer of that production line is likely to be a developed country with advanced technology and high level of automation?  The information revealed by Guan Fei this time was probably also developed in Japan.  Since the sources are the same, it is normal to consult this set of information!  "Zhu Qiang did not agree with his colleague's idea and retorted. "Experts just said that there is no research in this area in Japan!  When they were full, they stopped building gas-fired tunnel kilns and built more backward coal-fired tunnel kilns!  "Yu Min also disagreed with Zhu Qiang's point of view and argued. "Perhaps this is also intended to be exported to third world countries?  "Zhu Qiang could only defend Guan Fei from this perspective. "How could" Just as Yu Min was about to deny it, he heard a loud noise, and Shen Xiufeng suddenly slapped the conference table hard, his face rising.  Turning red, holding the information in his left hand and shaking it constantly, he asked excitedly: "Where did this information come from?  "    "Japan's?  "Zhu Qiang pursed his lips at Yu Min, indicating that you guessed wrong, and replied proudly. "Fart!  " Shen Xiufeng was furious, and the veins on his fingers were bursting: "Although I am sixty-two years old, I am not yet dim-sighted!  I saw a lot of familiar technology applications here, includingIt is only available in China and has never been seen in foreign products!  Moreover, it seems that the entire production line is completely in line with our research ideas. It can be said that it was developed for us - it is definitely designed in China!  The Japanese can do this, I write the character "Chen" backwards!  "
