上海第三钢铁厂薄板车间原有6座链式加热炉。这些炉子存在的问题是:链条和链爪带走的热损失严重(17％);空、煤气预热温度低(250～300℃);烧嘴多,炉压大,炉气外溢严重;炉体绝热性能差,操作环境恶劣,劳动强度高。另外,由于炉爪经常变形,使板坯直接与炉底砖接触,炉底砖被拉倒,擦伤坯料表面。 针对上述情况,在1984年结合车间大修将链式加热炉进行了改造,改造后的炉子采用了三段供
Shanghai Third Steel Works original six-sheet plant chain furnace. The problems with these furnaces are: severe heat loss from chains and claws (17%); empty, low gas preheating temperature (250-300 ° C); large burners, large furnace pressure, severe gas spill; furnace Body adiabatic performance is poor, poor operating environment, high labor intensity. In addition, due to frequent deformation of the furnace claw, the slab directly contact with the bottom of the brick, bottom brick was pulled down, the surface of the blank. In response to the above situation, combined with workshop overhaul in 1984 to chain furnace has been transformed, after the transformation of the furnace using three sections for
