摘要
结合鞍钢股份有限公司鲅鱼圈钢铁分公司1450双流板坯连铸中间包的生产实绩,对中间包控流装置、吹氩透气上水口、中间包覆盖剂及长水口保护浇注等相关中间包洁净化技术进行了改进与开发。应用结果表明,提升中间包钢液洁净化技术有利于降低中间包钢液中的T[O],可有效改善钢液的清洁度。
Based on industrial application of the process for cleaning molten steel in tundish in 1450 two-strand continuous slab-caster in Bayuquan Iron Steel Subsidiary Company of Angang Steel Co.,Ltd.,such equipments as tundish flow-control devices and the upper nozzle for argon blowing are upgraded,the performance of covering fluxes for tundish is improved and the process for cleaning molten steel in tundish is developed.Application results show that improving the process for cleaning molten steel in tundish is helpful to reduce the content of T[O] in molten steel and so the cleanliness of molten steel in tundish is improved effectively.
