氧化亚铁和碱度对高炉渣皮稳定性影响试验研究
|
摘要
针对高炉铜冷却壁热面渣皮稳定性下降、脱落的现象,采用试验研究对济钢高炉渣的软熔性和流动性进行研究。结果表明:碱度为1时,随着的增加,炉渣稳定性变差;为15%时,弱酸性的高炉渣稳定性较差;/R为10/1.1高炉渣的粘度变化对温度最不明显,稳定性是最好的。
In view of the phenomenon that the stability of hot surface slag of copper cooling stave of blast furnace is decreased and shedding, the soft melting property and fluidity of blast furnace slag in Jinan Iron and Steel Co. The results show that the stability of BF slag becomes worse with the increase of while the basicity is 1; the weakly acidic BF slag is most unstable while is 15%; the viscosity change of BF slag on the temperature is not obvious and the stability of BF slag is the best while/R is 10/1.1.
