废钢铁再生及在铸造行业的应用

Recycling of Steel Scrap and its Application in Foundry Industry

废钢铁的循环再生利用可以缓解我国钢铁工业资源匮乏、环境污染等问题,且节能减排效果明显,是我国钢铁产业和相关产业发展的必然趋势。概述了我国废钢铁资源状况、废钢铁在短流程炼钢和铸造行业的应用情况,并分析了国内外短流程炼钢的现状和废钢铁用作铸造原料的特点。

Due to relieving the issues of resource shortage and environmental pollution in China steel industry, steel scrap recycling is an inevitable trend of the development of China steel industry and the related industries. Moreover, its effect of energy conservation and emission reduction is intensely obvious. This paper summarizes the resource status of steel scrap in China and the application of steel scrap in mini-mill steelmaking and foundry industry. In addition, an analysis has been made on the current situation of mini-mill steelmaking at home and abroad, as well as the characteristics of steel scrap used as the raw materials in foundry industry.
