钢水浇注作业(Casting operation of liquid steel The term that refers to a technical process in which liquid steel with qualified chemical compositions is poured into a fixed shape solid according to the requires of rolling or forging. The two casting methods, the ingot casting or continuous steel casting methods, are generally used. Since the 1970's, the continuous casting has made considerable progress, but the ingot casting has died out gradually. 钢水浇注作业术语指的是根据轧钢或锻压的需要，将成分合格的钢水浇铸成具有一定形状固体的工艺过程。通常采用两种浇铸方法，即钢锭模浇注法和连铸法。自20世纪70年代以来，连铸获得了长足发展，模铸逐渐退出生产流程。)
板坯连铸操作(Submerged entry nozzles play a vital role in ensuring continuous slab casting operations, preventing oxygen and nitrogen pick-up of steel stream and achieving a desired flow in the mold. 浸人式水口在保证板坯连铸操作、防止钢水注流吸氧吸氮和获得结晶器内理想钢水流动方面起着至关重要的作用。)
【连】 变钢种操作(In the grade change operation, the tundish containing the old grade of steel being cast is first emptied to a certain depth before pouring the new grade from the ladle. 变钢种操作时，在由钢包浇人下一炉异钢种钢水前，首先将盛有上一炉正在浇注钢种钢水的中间包排空到一定深度。)
二次炼钢操作(Ladle furnaces are among the most widely used pieces of equipment in secondary steelmaking operations and range from relatively simple retrofitted installations to elaborately designed facilities. 在炉外精炼操作中最广为使用的设备是钢包炉。钢包炉可以是简单改造的设备，也可以是精心设计的设备。)
