摘要
介绍了某厂洁净钢生产过程中精炼渣控制工艺,对改质后精炼渣的各项性能进行了研究。结果表明,精炼渣的w(FeO+MnO)可以控制在3%以下,低熔点和低黏度保证了炉渣具有良好的流动性,炉渣溶解吸收Al2O3的速率较高,铸坯的洁净度水平很高。高光学碱度和高硫容量使得炉渣具有较强的脱硫能力。
The ladle slag control process in clean steel production is introduced and various properties of the modified refining slag investigated. Results show that the FeO and MnO quality fraction in the slag could be lowered to less than 3 % and low melting point and low viscosity ensured sound fluidity. The dissolution rate of Al2O3 into slag is relatively high, which resulted in high level of slab cleanliness. Strong desulphurization capability is obtained owing to the high optic basicity and desulfurization capability.
