oxygen blowing lance(The slag splashing process uses high pressure nitrogen, blown at high flow retes through the oxygen blowing lance, to splash slag onto the vessel refractory lining. 溅渣护炉工艺使用氧气喷枪喷出的高流量高压氮气将炉渣喷溅到转炉耐火衬上。)
water-cooled lance(Hot air at 1200°C is blasted into the top space of the Smelt Reduction Vessel through a water-cooled lance. 通过水冷喷枪将 1200°C 的热空气鼓人到熔融还原炉的上部空间。)
top mounted lance(In these combination blowing processes, 60 ~ 100% of the oxygen required to refine the steel is blown through a top mounted lance. 采用这些复吹炼钢工艺，精炼钢所需氧的60% ~ 100%是通过顶吹氧枪喷人炉内的°)
injecting oxygen through the top lance(Reheating of the steel is accomplished by injecting oxygen through the top lance in conjunction with aluminum additions. 通过顶枪吹氧配合加铝提温完成对钢水的加热。)
