随着钢铁企业生产的发展,渣山越来越大,如何开发利用这部份资源,是再生行业的一项重要内容。自1988年起,江苏省武进县物资再生利用公司把渣钢利用作为研究课题,从外引进人才,组织攻关,几年来取得了可喜成就。所谓渣钢是指钢厂不能用,含铁量低、杂质多、粒度小(8～12mm)的磁选粒钢。这部份资源十分丰富,过去一般是大的可用的搬走了,小的原封不动,有的填地铺路,有的则倒入农田和海边,仅马钢和上钢两大企业,每年就有渣钢30万吨以上。
With the development of steel production, the slag mountain is getting bigger and bigger. How to exploit this part of resources is an important part of the recycling industry. Since 1988, Wujin County, Jiangsu Province, material recycling companies to use steel slag as a research project, from outside the introduction of talent, research organizations, made gratifying achievements in recent years. The so-called slag steel refers to the steel can not be used, low iron content, impurities, small size (8 ~ 12mm) of magnetic grain steel. This part of the resources is very rich, the past is generally available for large removed, the small intact, some landfills, while others into the farmland and the sea, only the two major steel companies and steel each year There slag steel more than 300,000 tons.
