含碳添加剂浓度与黏土砂工艺排放--用苛化褐煤代替煤粉有可能减少铸造企业排放

Green Sand Emissions and the Concentration of Carbonaceous Additives--A Replacement of Seacoal with Causticized Lignite has the Potential to Reduce Foundry Emissions

铸造行业由于工艺的需要,在黏土砂造型中添加了破碎磨细的烟煤,也就是煤粉,或其他富含碳的添加剂,但是在生产过程中会排放气体。由于型砂中含碳添加剂的热解作用,其在铸造过程中会生成并释放出有害的大气污染物(HAPs)和挥发性有机化合物(VOCs)。
