摘要
钨是一种稀有金属 ,钨合金具有高的强度、硬度 ,较好的耐高温性、耐磨性和良好的电性能 ,广泛应用于航空航天工业、兵器工业、核工业、信息产业、汽车工业和钢铁工业等行业。目前 ,钨资源短缺 ,钨合金价格高、用量大 ,因此各国都把废弃的钨合金作为宝贵的第二钨资源加以再生利用。本文综述了钨合金的再生利用现状 ,分别总结了硬质合金、高比重合金、钨铜合金和钨材的再生利用技术 ,并利用生态环境材料的观点 。
Tungsten is a rare metal The strength, hardness, heat resistance, wear resistance and electricity property of Tungsten alloys are good Thus tungsten alloys are applied in the industries concerning space flight, weaponry, nuclear, communication, vehicle and iron and steel metallurgy Because of the shortage of tungsten resource and large consumption, tungsten alloys are expensive So that tungsten alloy scrap is considered as the second tungsten resource to recycle This paper reviewed the recycle of tungsten alloy scrap, and summarized the ways of recovering hard alloy, heavy metal, tungsten-copper and tungsten materials The recycle processes were evaluated in the sense of eco-materials
