| Abstract: | Based on the industrial test study of deep dephosphorization technique for making X70 pipeline steel with single slag operation in the 100 t top blown converter,some key parameters of the raw materials and operating duty are established during the blowing process.It is concluded that finished products with average content of 0.009 0% P can be produced when silicon content in hot metal is controlled in the range of 0.3%~0.6%,the blowing end point temperature is less than 1 700 ℃,the FeO content in the final slag is controlled lower than 26.45% even if the amount of slag is increased. |
| Keywords: | top blown converter dephosphorization technique single slag process |
