摘　　要：利用自制的实验平台,研究了高炉渣碱度对玻璃化率的影响。实验结果表明:二元碱度>0.9时,高炉渣的成棉率极小,以<3mm的高炉渣渣粒为主,且碱度对高炉渣玻璃化率的影响较大,玻璃化率下降速率较高;二元碱度为0.7~0.9时,粒化后的高炉渣出现大量的渣棉,成棉率在90%以上,且碱度对高炉渣玻璃化率的影响较小,玻璃化率均在99%以上。The experiment of the influence of basicity on glassy rate of BF slag was carried out on a self-made platform.The results show that when binary basicity>0.9,the wool forming rate is trivial,the granulated BF slag mainly containing particle which has the size of<3mm and the glass rate is deduced sharply;when the binary basicity located in 0.7~0.9,large amount of wool existed in the granulated BF slag,the wool forming rate is beyond 90%,and the basicity affect the glassy rate weakly,the glassy rate is over 90%.
