摘要
通过提高钢的洁净度 :P≤ 0 .0 2 0 % ,S≤ 0 .0 1 5 % ,As+Sn+Pb +Sb +Bi≤ 0 .0 5 0 % ,[O]≤ 30× 1 0 - 6 ,控制钢水过热度 :Δt=1 5~ 30℃ ,可以有效控制水平连铸管坯中间裂纹的产生和改善连铸坯的表面质量。
It is available to control the forming of middle crack of horizontal concasting tube bloom and improve the surface quality of tube bloom by increasing steel cleanliness: P≤0.020%, S≤0.015%, As+Sn+Pb+Sb+Bi≤0 050%, ≤30×10\+-\+6, and controlling the overheating of molten steel Δt=15~30 ℃.
