从事物资再生事业的科研单位以及为再生利用而生产加工设备的厂家,过去一直围绕着废钢铁加工成合格炉料打转转,重点放在制造各种打包机、剪切机和压块机上,为发展我国物资再生事业做出了一定的贡献。不过,国家对再生资源的开发利用,历来有一条“先利用,后回炉”的原则。它是符合我国国情的。从提高再生资源综合利用系数的角度来考察,对于能作为材料利用的资源就不作原料使用,能作为原料利用的就不作炉料使用,能用作炼钢炉料的就不用来炼
The scientific research institutes engaged in the recycling of materials and the factories that produce and process the equipment for recycling have traditionally focused on the processing of scrap steel into qualified chargers, focusing on the manufacture of balers, shears and briquettes, The development of China’s material regeneration has made some contribution. However, the development and utilization of renewable resources by the state have always had a “first use, after the return of furnace” principle. It is in line with China’s national conditions. From the perspective of improving the comprehensive utilization coefficient of renewable resources, we can not use raw materials for the resources that can be used as materials, and can not be used as raw materials, and can not be used for refining of steelmaking materials
