摘要
在分析出钢温度和过程温降影响因素的基础上,通过采取稳定出钢时间、完善合金料烘烤制度、钢包全程加盖、提高钢包周转率及低温快铸等措施,转炉平均出钢温度已稳定控制在1 635℃以下,出钢时间为2.4 min。出钢至钢包底吹氩处理、钢包周转过程及浇铸过程钢水温降分别降低20、11.1和25.9℃;钢包内衬烘烤温度由820℃上升至1 020℃。转炉寿命达到近24 000炉,石灰等消耗大幅降低。
On the basis of analysis on the affecting factors namely the tapping tempera- ture and the process temperature drop and by way of adoption of such a series of techni- cal measures as stabilizing the tapping time, perfecting the baking schedule of the alloy materials, full course covering for ladle, improving the turn-over rate of the ladle and casting speedily at low temperature,the average tapping temperature of the converter is steadily controlled within the level of 1 635 ＂C below and the tapping time is 2. 4 min. The molten steel temperature drop in the full course including tapping, argon blowing at the bottom of the ladle, ladle turn-over and slab casting is only 20, 11. l and 25.9 C separately. The inner lining baking temperature of the ladle rises from 820 C to 1 020 C. The converter service life reaches tion of lime is reduced greatly. approximately 24 000 heats and consump-
