高炉炉渣滞留量水模试验及分析

Hydraulic Model Experiment and Analysis on Retention of BF Slag

模拟高炉炉渣排放情况,设计开展水模试验,对炉渣滞留量影响因素进行分析。结果表明:油的黏度大,油的滞留量大;空隙度大,油的滞留量大;浮起高度大,油的滞留量小。由此可知,炉渣黏度降低、焦炭热强度提高和铁口数量增加有利于降低铁水带渣量;炉底死焦堆浮起高度越大越有利于炉渣排放。

A hydraulic model experiment on BF slag retention was made for simulation of the slag tapping in iron-making. Through analyzing affecting factors, the main results were as follow： high oil viscosity and porosity could aggravate oil retention and the floating height showed the opposite situation. So conclusions were drawn, with decrease of slag viscosity and increases of thermal strength of coke and the number of tap hole, the slag retention can be decreased; high floating height of fixed bed material is in favor of tapping slag completely.
