Practice of 250t converter slide gate slag-stopping technology in Meishan Steel
The slag-stopping technology,control mode and slide gate slag-stopping system maintenance of 250 t converter in Shanghai Meishan Iron & Steel Co.,Ltd.are introduced.By using the technology which combines slide gate slag-stopping and infrared slag detection,the fully automatic control of slag-stopping in tapping process has been achieved,the success rate of slag-stopping operation is up to 100％,the mass fraction of rephosphorization is decreased by 0.001 3 percentage points,the average service life of tapping hole is increased by 34 heats and the ferrous charge consumption is declined by 3 kg/t,consequentially good economic benefits have been obtained.
