摘要: 针对高炉渣制备矿渣棉的调质过程, 研究碱度对高炉渣黏度和熔化性温度的影响规律。根据矿渣棉的基本成分, 在熔融高炉渣中添加适量调质剂调整其化学成分, 并加热混匀。研究结果表明, 采用化学纯试剂对高炉渣进行调质时, 碱度升高使得熔渣黏度向短渣特性进一步转化, 熔化性温度升高, 不利于熔渣流动性的提高;碱度对调质高炉渣表面张力的影响不显著;制备矿渣棉适宜的碱度为1.0。

Abstract: According to the adjustment of molten blast furnace slag for preparation of mineral wool,the influence of iron tailings,basicity contents on the viscosity and melting temperature of the slag system has been investigated.Based on the basic composition of slag cotton,a certain amount of modifier was added into the molten blast furnace slag for adjusting chemical composition and then heated up and mixed. The result shows that when the blast furnace slag is adjusted with chemical reagent,the viscosity of the slag can transfer to the short-slag characteristics and the melting temperature increases with the increasing of basicity,which do not benefit for fluidity increasing of the slag.Basicity has not significant influence on the surface tension of blast furnace slag.The right basicity for preparation of slag cotton is 1.0.
