摘要
通过炼钢厂圆坯铸机生产的34Mn6钢工业性试验,得出:现有生产原料条件,在2~#VD真空炉其它工艺保持不变的情况下,正常天气,深真空时间10min,钢中w[H]达到2.5×10^(-6);深真空时间13 min,钢中w[H]可达到2×10^(-6)。下雨天气,要达到钢中同样的w[H]深真空时间较正常天气延长2 min。
Through the type approval test of 34Mn6 steel manufactured with casting machine of round billets,the results show that w[H]in the steel attains 2.5×10^-6 in 10 min.of deep vacuum time and 2×10^-6 in 13 min.of deep vacuum time with existing raw materials as well as other processes remaining constant at 2^#VD vacuum furnace and normal weather. Moreover,the deep vacuum time must be extended over 2 min.for the same w[H]when it rains.
