转炉钢渣一次处理方式对钢渣磁选粉收得率的影响研究

RESEARCH ON THE EFFECT OF ONE TIME TREATMENT METHOD OF CONVERTER STEEL SLAG ON THE YIELD OF STEEL SLAG MAGNETIC SEPARATION POWDER

试验使用某钢厂转炉一区在特定时期内采用同种炼钢方式产生的钢渣分别使用热泼、池式热焖、有压热焖三种不同的钢渣处理方式,探究在原料相同的情况下不同的钢渣一次处理方式对钢渣二次处理磁选粉收得率的影响。发现液态渣一次处置方式是影响磁选粉收得率的直接因素,热泼渣磁选粉收得率约是池式热焖和有压热焖的3.3倍。

This article explores the effect of different primary treatment methods of steel slag on the recovery rate of magnetic separation powder from secondary treatment of steel slag using three different steel slag treatment methods:hot splashing,pool type hot soaking,and pressure hot soaking,which are produced by the same steelmaking method during a specific period in the converter zone of a certain steel plant.It was found that the one-time disposal method of liquid slag is a direct factor affecting the yield of magnetic separation powder.The yield of hot splashed slag magnetic separation powder is about 3.3 times higher than that of pool type and pressurized hot soaking.
