转炉出钢口的使用寿命直接影响转炉的工作效率、耐火材料成本和钢的质量。当出钢口袖砖内径过大和袖砖长度及出钢时间变短时,则应更换出钢口。造成上述问题的原因主要是出钢过程中钢水和渣的腐蚀。出钢口内径过大造成出钢流量大,致使出钢时间过短。若出钢时间过短,控制带渣 The service life of the tapping hole of the converter directly affects the work efficiency of the converter, the cost of the refractory material and the quality of the steel. When the tapping brick tapping hole is too large and the length of the cuff and tapping time becomes shorter, you should replace the tap. The main reason for the above problems is the corrosion of molten steel and slag in the tapping process. Tapping the inner diameter is too large, resulting in tapping flow, resulting in tapping time is too short. If the tapping time is too short, the control with slag
