摘要为了研究微合金化钢因硫含量超标而导致成品钢材出现裂纹等质量问题,以船板钢C36-1为研究对象,通过采用多因素多水平正交回归的试验方法进行了钢包渣洗脱硫剂的组分设计研究,根据实验室基础试验数据建立了脱硫剂的组分设计模型。结果表明,当脱硫剂中w(CaO)=42%~55%时对脱硫率的影响较为明显。w(Al₂O₃)<35%以下、w(CaC₂)=12%较为合适。经工业生产试验验证,脱硫剂的组分最终确定为w(CaO)=42%~55%、w(Al₂O₃)=30%~35%、w(CaC₂)=8%~12%、w(CaF₂)=8%~10%。该脱硫剂的工业平均脱硫率达到了80.93%。新型脱硫剂的使用稳定控制了船板钢钢液中硫质量分数至0.010%以下,铸坯裂纹判废率降低了85%左右,满足了企业对该类钢种控硫的工艺需求,增加了企业的经济效益。

Abstract：It wanted to study and solve the quality problem of cracks in microalloyed steel due to excessive sulfur content, the composition design of desulfurizer for slag infiltration of ship plate C36-1 was studied by using multi-factor and multi-level orthogonal regression test method, and the composition design model of desulfurizer was established according to the basic laboratory experimental data. The results showed that when the w(CaO)=42%-55% in desulfurizer, the effect on desulfurization rate was more obvious. w(Al₂O₃)<35%, w(CaC₂)=12% is appropriate. After industrial production test, the final determination of the components of desulfurizer was w(CaO)=42%-55%、w(Al₂O₃)=30%-35%、w(CaC₂)=8%-12%、w(CaF₂)=8%-10%. The industrial average desulfurization rate of the desulfurizer reached 80.93%. The new desulfurizer can stably control the sulfur content of ship plate steel to less than 0.010%. The failure rate of slab crack was reduced by 85%. It met the process demand of sulfur control for this kind of steel and increased the economic benefit of the enterprise.
