冶炼企业和机械制造企业产生大量的金属废料,其回收工艺正面临着严格的环保要求。经验表明,利用铸造车间的传统炉子来熔炼受污染的零散金属废料是不合理的,因为用传统炉子来处理钢屑和生铁屑,会导致炉子产能降低、能耗超标、经济参数下降和合金质量恶化。此外,金属废料回收还存在一个更为复 Smelters and machinery manufacturing enterprises produce a large amount of metal scrap, the recovery process is facing strict environmental requirements. Experience has shown that it is unreasonable to use smelters to contaminate scattered scrap metal by using conventional furnaces in a foundry, since the use of conventional furnaces for the treatment of steel chips and pig iron chips leads to reduced furnace capacity, excessive energy consumption, reduced economic parameters and alloy quality deterioration. In addition, the recovery of metal scrap there is a more complex
