本文介绍了本钢特殊钢厂采用40 tEBT-LF-VD-3流235mm×265mm方坯连铸-热轧工艺生产Φ85mmSA-182F12C1.1锅炉吊杆钢材。通过对炼钢过程的成分控制,严格中包钢水过热度,稳定过程拉速,采用结晶器弱冷制度连铸工艺生产该钢种,铸坯质量和轧后钢材性能满足标准要求,达到了取代模铸生产的目的。
This article describes the Benxi Iron and Steel Company special steel 40 tEBT-LF-VD-3 flow 235mm × 265mm billet continuous casting - hot-rolled production Φ85mmSA-182F12C1.1 boiler boom steel. By controlling the composition of the steelmaking process, strictly superheating molten steel, stabilizing the process of pulling speed, the use of low-temperature mold continuous casting process of the production of steel, billet quality and performance of rolled steel to meet the standard requirements, reached Replaces the purpose of molding production.
