一般中小型铸造车间广泛采用的铸件回火炉,大多数是耗煤量大,烟囱排烟严重的旧式燃煤炉,这种炉子由于炉体结构不合理,致使燃煤燃烧不充分,燃料浪费大,而且燃烧过程中烟囱排放大量黑烟,严重污染环境。为解决此问题,我们对无锡船厂铸工车间的一座大型铸件回火 Generally used in small and medium-sized foundry furnace casting furnace, most of the coal consumption is large, the chimney smoke serious old coal-fired furnace, the furnace due to unreasonable furnace structure, resulting in inadequate combustion of coal, fuel waste , And the chimney in the combustion process emits a large amount of black smoke, which seriously pollutes the environment. To solve this problem, we temper a large cast iron foundry in Wuxi Shipyard
