随着我国工农业为飞速发展,可锻铸铁的用量日益增长。因此,废钢供应不足与产量急速增长的矛盾就突出的暴露出来了,解决废钢不足的问题,在当前有着极其重要的意义。切削加工下来的钢屑、铁屑(指可锻铸铁,下同),应该是废钢的一个重要来源。我厂为了解决以钢屑、铁屑代替废钢熔炼高牌号可缎铸 With the rapid development of industry and agriculture in our country, the amount of malleable iron is increasing day by day. Therefore, the contradiction between the shortage of scrap steel and the rapid growth of output has been highlighted. The solution to the shortage of scrap steel has extremely important significance at present. Cutting chips, iron filings (malleable cast iron, the same below), should be an important source of scrap. I plant in order to solve the scrap steel, iron scrap instead of smelting high grade satin casting
