摘要
莱钢特钢事业部新区采用铁水+废钢→100t电炉→双工位LF→双工位VD→圆坯连铸(650mm)→步进式加热炉→950轧机轧制的流程生产高压锅炉管钢12Cr1MoV,通过优化冶炼工艺、调整精炼渣系、强化保护浇铸等措施,克服了12Cr1MoV钢在实际生产中的困难,使12Cr1MoV钢的化学成分、低倍以及非金属夹杂物评级等各项指标均满足用户要求。
The high pressure boiler tube steel 12Cr1 MoV was produced with the path of hot metal+scrap→100t EAF→double LF→ double VD→ round billet continuous casting(section 650mm),in the special steel division new district of Laiwu Steel.The difficulties that existed in the actual production of 12Cr1 MoV can be overcame with the methods of the reinforcement smelting process,adjusting the refining slag,strengthen protective casting and so on.So the chemical composition,low power structure,non-metallic inclusions rating and other indicators of the12Cr1 MoV meet the customers requirement.
