Information
Beijing, September 15, CCTV (reporter Liu Tiansi) on September 14, Jidong Baoxin silicon carbide Co., Ltd. independently developed the "fully enclosed mobile silicon carbide smelting furnace technology" under the chairmanship of the director of the scientific and technological achievements transformation cooperation committee of China Hi Tech Industrialization Research Association and the director of China Machinery Industry Federation passed the scientific and technological achievements appraisal of China Machinery Industry Federation The skill level reached the level.
 
 
 
The project is the first closed smelting of silicon carbide in China, which solves the problem that the furnace gas of silicon carbide cannot be recovered in the smelting process, and reduces the production cost of silicon carbide by sending the recovered furnace gas to the power station for power generation. The problems of non environmental protection, non energy saving and great harm to the employees are solved. In this technology, nitrogen is used to replace the oxygen in the closed space, and various instruments are used to monitor the whole process of furnace gas from generation, transmission and combustion at any time, so as to ensure the safety of each link, forming a unique technical system, which is suitable for industrial continuous production.
 
 
 
For the first time in China, the silicon carbide smelting furnace is sealed in a closed kiln body. The oxygen in the kiln body is first removed by nitrogen. The furnace gas generated after power on is washed and purified by the washing tower, and is transmitted to the self-contained power station by positive pressure of Roots blower for power generation. The power supply aluminum bar is set in the underground gallery to avoid the difficulty of high altitude pipeline maintenance and the impact on the running of the train. This technology is simple and easy to use, especially in winter, the original open burning process is affected by outdoor temperature, the insulation effect is poor, and the furnace output is relatively reduced. After the use of "fully enclosed mobile silicon carbide smelting furnace", the heat loss can be reduced and the output is relatively increased. Through repeated practice, the purity of green silicon carbide and black silicon carbide are over 98.5% and 97.5% respectively, which are in line with the relevant national standards, advanced technology and reasonable process. At present, the artificial smelting of silicon carbide has a history of more than 100 years. For a long time, the problem of furnace gas recovery has been a problem for many scholars and manufacturers. Some scholars only obtained relevant data in the laboratory, which is still a long way from industrial production.
 
 
 
With the strengthening of the national legal system in environmental protection and people's awareness of environmental protection, the original smelting method has not been able to meet the development requirements of the current market. If the silicon carbide industry does not carry out industrial upgrading, it will certainly withdraw from the stage of history. The company has broken through the barrier of furnace gas recovery and developed a highly stable "fully enclosed mobile silicon carbide smelting furnace". Based on the summary of predecessors, this technology has made a revolutionary creation and invention for the recovery of silicon carbide smelting furnace gas. It can not only smelt green silicon carbide, black silicon carbide, but also smelt graphite fossil oil coke.
 
 
 
The technical achievements of the project are expected to reach several billion yuan, which can promote the healthy development of high energy consumption and high pollution industries such as silicon carbide and graphitized petroleum coke. Through its original technology research and development, it will expand the application scope of products, reduce the production cost of products, and have great social and economic benefits.
