抑制氩氧炉渣粉化的研究

摘要

通过实验室模拟氩氧炉(AOD)渣出渣过程,调整AOD渣冷却方式,研究矿物C2S晶型转化规律,加入矿物稳定剂碳酸钠和氧化硼对AOD渣的粉化进行研究.试验结果表明,AOD渣主要硅酸盐矿物C2S均发生晶型转化而导致严重粉化现象.矿物稳定剂碳酸钠和氧化硼对AOD渣的粉化起到抑制作用,抑制效果B2O3大于Na2CO3.%In this paper, through the laboratory simulation argon oxygen furnace(AOD) slag slag process, adjusting the argon oxygen furnace(AOD) slag cooling way to study mineral C2S crystal transformation rule, add sodium carbonate mineral stabilizer and boron oxide of argon oxygen furnace(AOD) slag powder were studied. The results showed that the C2S of the main silicate minerals in argon oxygen furnace(AOD) slag were transformed and the phenomenon of severe pulverization occurred. The effect of mineral stabilizer sodium carbonate and boron on the powder of argon oxygen furnace(AOD) residue was inhibited, and the inhibition effect was greater than that of sodium carbonate.
