1. 前言轧钢连续式加热炉采用架空型炉底结构之后,均热段的滑轨成了关键.均热段一般采用高铬铸钢的半热滑轨,也有用水冷滑轨的.首先,由于水管无法绝热包扎,造成大量热损失;其次,消耗大量价格昂贵的金属材料;第三,板坯有黑印.故寻找一种适合板坯加热用的滑轨结构是十分必要的.1965年在板坯加热炉上曾试用过一种特殊结构 1. Introduction rolling continuous furnace with overhead type bottom structure, the heat section of the slide has become the key.Drying section are generally high-chrome cast steel semi-hot slide, but also useful water-cooled slide.First, Second, it consumes a large amount of expensive metal materials. Thirdly, the slab has a black seal, so it is necessary to find a suitable slide structure for slab heating. A special structure has been tried on slab furnaces
