铸造专业使用燃煤炉较多,主要有退火炉和大型烘模炉等。大部分是手工加煤,机械鼓风,劳动条件差,耗煤量大。还由于燃烧不完全,烧炉时黑烟滚滚,污染严重,对环境和人体的危害较大。因此,探讨铸造工业炉窑如何消烟除尘、节约能源、改善环境就具有很大的现实意义,也是铸造行业急待解决的一项任务。 Foundry professional use of coal-fired furnace more, mainly annealing furnace and large baking furnace. Most of the manual coal, mechanical blast, poor working conditions, large coal consumption. Also due to incomplete combustion, black smoke rolling furnace, serious pollution, the greater the harm to the environment and human body. Therefore, it is of great practical significance to explore how to eliminate dust, save energy and improve the environment in the foundry industrial kilns. It is also a task urgently needed in the foundry industry.
