电炉炼钢所用炉料品种不断增加,钢水含硫量较高,这就导致需要除去更多的硫。采用具有较大搅动能力的搅动透气塞来增加单位时间的气流量来增加钢包中钢水的搅动能量,可以减少钢包冶金炉的脱硫时间。发现当两个透气塞同时有气体流动时,增加第二个搅动透气塞的流量可以进行快速的搅动。但是增加的气流和用两个透气塞代替一个透气塞加剧了钢包渣线处的湍流,导致了较大的机械冲刷和钢包耐火材料的侵蚀,使钢包耐火材料的工作衬炉役缩短。
Furnace steel used in the growing variety of charge, the higher the sulfur content of molten steel, which led to the need to remove more sulfur. Adopting the agitating breathable plug with larger stirring capacity to increase the air flow per unit time to increase the stirring energy of the molten steel in the ladle can reduce the desulphurization time of the ladle metallurgical furnace. Found that when the two breathable plug gas flow at the same time, increasing the flow rate of the second stirring breathable plug can be quickly agitated. However, the increased airflow and the replacement of a breathable plug with two breathable plugs exacerbated the turbulent flow at the ladle slag line, resulting in large mechanical erosion and erosion of the ladle refractories, shortening the service life of the ladle refractories.
