×钢厂共有3座120吨氧气顶吹转炉。2号炉主轴(直径850mm,材质40铬钢)在投产吹炼61炉后断裂,运行时间共234小时。为分析原因总结经验,我们和有关单位一起对转炉倾动机构在运转中的实际负荷情况进行测试。由于2号炉还未恢复生产,测试工作在3号炉上进行。3号炉与2号炉设计相同,但具体的制造、安装、调整、运转操 × A total of three steel 120 tons of oxygen top blowing converter. Furnace No. 2 (diameter 850mm, material 40 chrome steel) after the commissioning of furnace 61 furnace rupture, the running time a total of 234 hours. To analyze the reasons for summing up the experience, we and the relevant units on the converter tilting mechanism in operation in the actual load test. As furnace No. 2 has not yet resumed production, the test was carried out on furnace No. 3. No.3 furnace and No.2 furnace design the same, but the specific manufacture, installation, adjustment, operation operation
