摘要
介绍了海管用钢HSL450S成分设计思路。首次在EAF-LF-VD-CC生产线进行HSL450S钢试生产。通过电炉钢水终点成分控制,确保冶炼工艺顺行。试制时HSL450S钢成分和温度控制较好,钙处理和软吹氩工艺执行到位,水口未发生结瘤。
The composition design of HSL450S steel for submarine pipe is introduced in this paper. The EAF--LF--VD--CC process was firstly used in the trial production of HSL450S in Hengyang Steel Tube (Group) Co. Ltd. Through controlling the final composition of molten steel in EAF, smooth smelting operation was ensured. During the trial production period, the composition and temperature of HSL450S were in good control, calcium treatment and argon rinsing were full executed and no nodulation was formed on the casting nozzle.
