摘　　要：河钢宣钢二钢轧厂炼钢工艺设施主要有2座150 t转炉,2座LF精炼炉,1座RH精炼炉,2台12机12流方坯连铸机。投产以来,中包烘烤器、大包滑动水口、大包臂回转升降,切后辊道作为连铸生产中的承上启下工艺,发挥着重要的纽带作用,是重要的生产工艺设施。随着企业降本增效、转型升级工作的深入推进,设备存在的安全隐患为生产埋下了极大的隐患。为了降低故障率,节省备件费用,公司积极抓紧时间对中包烘烤器、大包滑动水口、切后辊道控制系统进行升级改造。There are two 150-ton converter,two LF refining furnace,one RH Refining Furnace,two 12-unit 12-strand billet caster in the steel-making process facilities of No.2 Rolling Mill of Xuanhua Steel.Since it has been put into production,the bale baking machine,the bale sliding nozzle and the bale arm swing up and down,the cut-back roller table plays an important role as a link in the continuous casting production,and is an important production process facility.With the deepening of cost-cutting and efficiency-increasing,transformation and upgrading of enterprises,the potential safety problems of equipment have laid a great hidden trouble for production.In order to reduce the failure rate and save the spare parts cost,we take the time to reform the package baking machine,the package sliding nozzle,the post-cut roller table control system.
