废金属是炼钢、铸造,生产中小农具和小五金产品的重要原材料。搞好废金属的回收利用工作,对于促进我国冶金工业的发展,到本世纪末我国实现工农业总产值翻两番的宏伟战略目标有着密切的关系。随着国民经济的稳步发展,对钢的要求量必将会越来越大,这就要求我国钢的产量相应发展。而钢产量增加,首先要求炼钢原料相应增加。增加炼钢原料,一方面靠增加生铁产量,另一方面靠回收废钢铁,多用废钢炼钢,即提高废
Scrap metal is an important raw material for steelmaking, foundry, small and medium-sized farm implements and hardware products. Doing a good job of recycling scrap metal is of great significance to promoting the development of China’s metallurgical industry and achieving the grand strategic goal of quadrupling the gross industrial and agricultural output by the end of this century. With the steady development of the national economy, the demand for steel will surely become larger and larger, which requires the steel production in our country to develop accordingly. The steel production increased, first of all require a corresponding increase in steelmaking raw materials. Increase the raw material for steelmaking, on the one hand by increasing pig iron production, on the other hand by recycling scrap iron, steel scrap and more, that is to raise waste
