废钢是炼钢的主要原料之一。用废钢回炉炼钢,不仅可以降低生产成本,提高生产率,还能减少环境污染。工业发达国家如英、美、苏、日、西德等大量使用废钢炼钢,废钢利用量占整个钢产量的30～50％,甚至高达60％。我国废钢资源丰富,但由于废钢加工处理设备相当落后,炼钢生产所吃的废钢只占钢产量的25％左右。据有关统计资料介绍,到目前为止,我国已经投产使用的废钢加工设备只有170台左右,其中100～150t废钢打包机约60台,800～1250t废钢剪切机约10台,钢屑破碎(加工)设备100台左右,远远适应不了钢铁生产发展的需要。因此,研制和开发废钢加工处理设备,并使其系列化,是刻不容缓的事情。 江苏冶金机械厂在完成冶金工矿备件和大型非
Steel scrap is one of the main raw materials. Steel scrap recycling, not only can reduce production costs, increase productivity, but also reduce environmental pollution. The industrialized countries such as Britain, the United States, the Soviet Union, Japan, West Germany and other large-scale use of scrap steel, scrap utilization accounted for 30 to 50% of the steel production, or even up to 60%. Scrap is rich in resources in our country. However, due to the rather backward processing and processing equipment of scrap, the scrap consumed in steelmaking production accounts for only about 25% of the steel output. According to the statistics, there are only about 170 scrap processing equipments in operation in China so far, of which about 60 are from 100 to 150t scrap balers and 10 are from 800 to 1,250 t scrap shearing machines. ) Equipment 100 or so, far can not meet the needs of the development of steel production. Therefore, it is an urgent matter to develop and develop scrap processing equipment and to serialize it.
