南乌拉尔机器制造厂制造了苏联第一批100～1 30吨氧气转炉。在设计中,遇到了一些困难,缺乏计算强度和刚度的验算法。因此,南乌拉尔机器制造厂曾研究和验算了转炉的计算方法,对由金属和有机玻璃制成的模型进行了试验,并测定了起动前和起动过程中转炉本身的应力。对称的转炉炉体由炉罩,上面固定有支承耳轴的圆柱形承压弦带和下部截头圆锥组成。截头圆锥体同重为70吨的可分离式炉底连接,而炉底同螺栓与炉体连接。圆锥部分和炉底由厚为50毫米钢板做成;而圆锥形承压弦带由厚为100毫米的钢板制成,并用两 South Ural machine manufacturing plant made the first Soviet 100 ~ 130 tons of oxygen converter. In the design, we encountered some difficulties, the lack of calculation method of calculating the strength and stiffness. Therefore, the South Ural Machine Works has studied and verified the calculation of the converter, the model made of metal and plexiglass was tested and measured before and during start-up process of the converter itself stress. Symmetrical converter furnace body consists of a furnace cover, on which a trunnion bearing cylindrical trunnion bearing a trunnion and a lower truncated cone are fixed. The truncated cone has a 70 ton detachable bottom and the bottom of the furnace is bolted to the furnace. The conical part and the bottom of the furnace are made of 50 mm thick steel plates, while the conical pressure bearing chords are made of steel plate with a thickness of 100 mm,
