1 前言 20世纪80年代以来,中国钢铁工业进入了快速发展阶段。1995年我国生铁产量超过1亿t。从表1可见,与1998年相比,1999年全国炼铁企业技术经济指标取得了很大进步,无论是重点企业或是地方骨干企业,其高炉利用系数、煤比、焦比、风温使用水平等技术经济指标得到明显改善。高炉利用系数升高和焦比降低幅度较大,是近年来进步最快的。这说明了一个问题:即进步源于压力,没有压力就难以进步。
1 Preface Since the 1980s, the Chinese steel industry has entered a phase of rapid development. In 1995, China’s pig iron production exceeded 100 million tons. As can be seen from Table 1, compared with 1998, the technical and economic indicators of the ironmaking enterprises in the country have made great progress in 1999. Whether it is a key enterprise or a local backbone enterprise, the blast furnace utilization coefficient, coal ratio, coke ratio, air temperature Level and other technical and economic indicators have been significantly improved. Blast furnace utilization coefficient and coke ratio to reduce the larger rate is the fastest progress in recent years. This shows the problem that progress comes from stress and that progress without pressure is difficult.
