【摘要】 每年电石乙炔法生产PVC产生的超过两千万吨(干基)电石渣中含有约20万吨硅铁。电石渣中硅铁的存在对熟料烧成有积极作用,但加速了生料粉磨设备耐磨件的磨损。更多还原

【Abstract】 There are around 200,000 tons of ferro-silicon contained in over 20 million tons of carbide slag(on dry basis),which were generated from PVC production by means of acetylene method annually.Existence of ferrosilicon contained in carbide slag represents active actions to clinker pyro-processing,but it will accelerate wear rate of wearable parts in raw meal grinding equipment.更多还原
