原设计年产10万t电解铜的金隆公司,通过生产挖潜和局部设备改造,电解铜产量提高到15万t,电铜加工成本每吨降低400元。此项改造后,其炼铜PS转炉的冰铜装入量由每炉160t增加到230t,满足了公司扩产后对转炉的能力要求。本文介绍了转炉改造的加长方法、内容及特点,重点阐述了改造中转炉驱动系统方案的设计选择及采用伞齿 圆柱齿减速机的实际使用效果,为相关转炉扩容改造提供了实践经验。
The original design of 100,000 tons of electrolytic copper Jinlong company, through the production of potential and partial transformation of equipment, electrolytic copper production increased to 150,000 t, electro-copper processing costs reduced by 400 yuan per ton. After this transformation, its copper smelting copper converter copper loading from 160t per furnace increased to 230t, to meet the company’s capacity expansion after the converter requirements. This paper introduces the lengthening method, contents and features of the converter retrofitting. The design options of the converter system and the practical use of the bevel gear reducer are expounded emphatically, which provide practical experience for the relevant converter expansion retrofitting.
