双屑(钢屑和铁屑)是机械制造业中的一项数量较大的副产品。由于我国钢铁和机械制造业不发达,提供给炼钢用的废钢严重不足。因此,如何利用价格低廉的双屑代替一部分废钢铁炼钢,就有着重大的现实意义。这不仅能解决一部分废钢来源的困难,又使双屑得到合理利用,变废为宝,并为降低电耗,降低钢的成本,起到一定作用。所
Duffels (steel filings and scrap iron) are a large number of by-products in the machinery industry. Due to the underdevelopment of China’s steel and machinery manufacturing industry, the amount of scrap provided to steelmaking is seriously insufficient. Therefore, how to use low-cost double-chip scrap instead of replacing part of the steel, there is a great practical significance. This not only can solve part of the difficulties of scrap sources, but also make the double crumbs reasonably utilized, turning waste into treasure and playing a certain role in reducing power consumption and reducing the cost of steel.
