卡尔多炉支撑托辊结构创新与应用

Innovation and Application of Supporting Roller Structure for Kaldor Furnace

卡尔多炉是一个即可前后倾动,又可绕炉体中心轴线旋转的冶炼炉窑,用于吹炼自热炉产出的粗铜。由于炉体在吹炼时始终保持连续旋转状态,故卡尔多炉支撑托辊故障率较高,极大影响生产效率。同时,检修维护量大,每年均会消耗大量的备件费与维护检修费用,设备运行及维护成本居高不下。本设计对卡尔多炉支撑辊的结构进行了优化,大大降低了炉体旋转过程中托辊所受轴向摩擦力,从而延长支撑托辊的使用寿命。

The kaldor furnace is a smelting furnace that can be tilted forwards and backwards and can rotate around the central axis of the furnace body.It is used for blowing the blister copper produced by the self-heating furnace.Since the furnace body always keeps continuous rotation during the blowing process,the failure rate of the supporting roller of the kaldor furnace is relatively high,which greatly affects the production efficiency.At the same time,the amount of overhaul and maintenance is large,which consumes a large amount of spare parts and maintenance costs every year,and the cost of equipment operation and maintenance remains high.The design optimizes the structure of the support roller of the kaldor furnace,which greatly reduces the axial friction of the roller during the rotation of the furnace body,thereby the service life of the support roller is extended.
