Technology Research of Ningsteel Sintering Machine Waste Heat Recycling
Abstract: This design is just about ning gang sintering machine waste heat recycling, recycling study how effectively heat to circulate. We started with the far infrared thermometer, presses, flue gas analyzer, U -shaped tubes, and other high-tech equipment for sintering machine rather just bellows, ESP, vehicles, pipelines and other tests have been carried out several static, a series of accurate data dynamic pressure, gas composition, wind, gas volume, the material surface temperature, car speed, ambient temperature, test temperature of graduation to do a good preparation. The graduation project is to understand the basic content of the basic processes of steel production process, familiar sintering machine basic structure and operation mode, the regional component of the measured exhaust gas temperature and sintering machine , according to the temperature of the flue gas heat recovery research program to develop waste heat recovery way to calculate the amount of waste heat recovery , and to analyze the economy. The graduation project focuses on the difficulties and material balance and heat balance calculations. I think I graduated from the design through the machine can learn more about the steel production process , the value of waste heat recovery , waste heat recovery methods. And,engaged in the profession for the future direction of the work to lay the foundation.
