ABSTRACT The influence of the addition amount of conditioning agent, gas quenching pressure, nozzle type and slag temperature on gas quenching effect of basic oxygen furnace (BOF) steelmaking slag were studied through the gas quenching system. The results show that the gas quenching rate basically increased with the increase in the amount of the conditioning agent by using BF slag as a conditioning agent. High gas quenching pressure and high Mach number of nozzle had a slight promotion effect on gas quenching rate. While the modified slag temperature had a significant influence on the gas quenching rate. The higher the slag temperature and the superheat degree, the higher the gas quenching rate. Gas-quenched steel slag micro-beads property is related to the amount of the conditioning agent. The granulation effect became worse and the mineral phases gradually changed to the glass phase with the increasing amount of the conditioning agent.

用重熔改性转炉炼钢渣气淬制备微珠的研究

摘要 通过气淬系统研究了调质剂添加量、气淬压力、喷嘴类型和炉渣温度对碱性氧气转炉（BOF）炼钢炉渣气淬效果的影响。结果表明，以高炉渣为调质剂，气淬速率随着调质剂用量的增加而基本提高。高气淬压力和高马赫数对气淬速率有轻微的促进作用。而改性渣温度对气淬速度有显着影响。炉渣温度和过热度越高，气淬速度越高。气淬钢渣微珠的性能与调节剂的用量有关。
