我国中小钢铁厂遍布全国,工艺技术落后,设备陈旧,能耗高,经济效益差。据统计,1983年全国54个中小企业的吨钢综合能耗为1.854t标准煤,个别企业竟高达3.8～16.2t标准煤。小钢联的产量约占全国总产量的20～25％,而能耗却占30～35％。因此,小钢铁厂必须依靠科学技术进步迅速改造,否则将成为全国钢产量翻番的严重障碍。 China’s small steel plants all over the country, backward technology, outdated equipment, high energy consumption, poor economic efficiency. According to statistics, in 1983, the comprehensive energy consumption per tonne of 54 small and medium-sized enterprises in the country was 1.854t of standard coal, while that of some enterprises was as high as 3.8 ~ 16.2t of standard coal. The small steel production accounts for about 20% to 25% of the national output, while the energy consumption accounts for 30% to 35%. Therefore, small steel mills must rely on scientific and technological progress to rapidly transform or else they will become a serious obstacle to doubling the country’s steel output.
