摘　　要：2007年底宣钢进行品种结构调整,将120 t转炉—130 t LF精炼炉—12流方坯连铸机生产线的6号连铸机转为生产200 mm×285 mm断面大方坯品种钢。宣钢炼钢厂为满足大方坯品种钢生产需要,对6号连铸机进行了设备改造及品种钢生产工艺优化,改进后大方坯品种钢的热顶锻合格率、低倍合格率达到99%以上,成材率大幅度提高。Variety and structure of products in Xuan Steel are adjusted in 2007. The 6# caster of 120 t - converter - 130 t - LF - refining - furnace - 12 - flow square - billet - caster production line is turned to produce Large - scale square billet grade steel of 200 mmx 285 ram. To produce it, equipment is reformed and the grade production process optimized. After that it both reaches over 99 percent on the qualified ratio of hot heading upsetting of large - billet steel and qualified ratio of low - times examine.
