采用气动钢渣浇口塞的结果,使钢渣转入钢水包的数量大为减少。所得到的好处是回磷量减少、铝的利用率提高和钢水得到净化以及延长钢水包寿命。操作时钢流可由喷嘴出来的压缩空气切断,喷嘴从炉子外部插入出钢口,从喷嘴与出钢口之间的间隙引入空气以改善密封作用。 As a result of the pneumatic steel sprue plug, the amount of slags transferred to the ladle is greatly reduced. The benefits gained are reduced levels of phosphorus replenishment, improved utilization of aluminum and clean-up of molten steel and extended ladle life. During operation, the steel flow can be cut off by the compressed air from the nozzle. The nozzle is inserted into the tapping hole from the outside of the furnace, and air is introduced from the gap between the nozzle and tapping hole to improve the sealing effect.
