一个必须改进的是出钢口的堵塞,原来的方法是从渣门伸入喷枪堵住出钢口,但封堵不严。利用清理平台从外面封堵就解决这一问题。第二个必须改进的是为获得95％的操作自动化,必须把空气压力从6kg/cm~2提高到12kg/cm~2。第三个是尾砖钢压盖,投产初期,尾砖每20炉就需更换,改进后,寿命可达90～120炉,并可持续使用。操作方法一旦熔池中钢的成分和温度达到要求,先 A must improve is the tapping of the tapping hole. The original method is to block the tap hole from the slag door into the lance but the sealing is not strict. The use of clean-up platform from the outside plug to solve this problem. The second must be improved to obtain 95% of the operation automation, the air pressure must be increased from 6kg / cm ~ 2 to 12kg / cm ~ 2. The third is the tail brick steel gland, put into operation early, tail brick every 20 furnace will need to be replaced, improved, the life expectancy of up to 90 ~ 120 furnaces, and sustainable use. Method of operation Once the composition and temperature of molten steel pool meet the requirements, first
