摘要
济钢第三炼钢厂采用中薄板坯铸机(ASP)生产超低碳钢,利用LF-RH/TCOB精炼工艺解决了钢水的可浇性及钢水中[C]等成分的控制问题。通过确定精炼过程中各阶段的提升气流量、钢包渣系及TCOB吹氧脱碳处理氧枪参数等,对关键工艺参数进行优化,实现了连续浇钢6炉以上,成品碳含量[C]<50×10-6,全氧含量可达到30×10-6以下。
The No.3 Steelmaking Plant of Jinan Iron and Steel Co., Ltd. adopted ASP caster to produce the ultra low carbon steel, solved the pourability of the molten steel and control question of composition such as[C]by LF-RH/TCOB refining. Through confirming the flow rate of lift gas circulation in the course of refining, the slag system in the ladle and the parameters of the TCOB, the key parameters were optimized. Therefore, continuous casting steel for more than six heats was realized, the carbon content in the finished product was less than 50×10^-6 and the total oxygen content reached below 30×10^-6.
