化学成分对高炉炉渣冶金性能影响研究现状
|
摘要
高炉炉渣的冶金性能对高炉的顺行、脱硫、长寿有着很重要的影响,有必要对其冶金性能机理进行深入研究。综述了碱度、Al_2O_3、MgO等化学成分对冶金性能的影响,不同组分对炉渣的冶金性能影响是不同的。通过此研究,对影响高炉炉渣冶金性能的机理有了更全面的认识,并为以后改善高炉炉渣的冶金性能提供了借鉴。
The metallurgical property of blast furnace slag was significant for high furnace line, desulphurization and long life. Therefore, it was necessary to conduct in-depth study on its metallurgical performance mechanism. The effects of alkalinity, Al_2O_3 and Mg O on metallurgical properties are reviewed. The effects of different components on metallurgical properties of slag are different. The mechanism of the metallurgical properties of blast furnace slag is more fully understood, and the metallurgical properties of blast furnace slag are also provided.
