去年,我国钢产量首次突破了6000万吨,居世界第四位。 但是,衡量一个国家钢铁工业的发展水平,既要看数量,更要看品种和质量。近10多年来,我国钢材品种结构出现了一些可喜的变化,板、管钢材产量的增长幅度超过了钢产量的增长幅度,占钢材总量的比重(板管比)达到36％;能源、交通、原材料等基础工业部门需要的各种
Last year, China’s steel output exceeded 60 million tons for the first time, ranking the fourth in the world. However, to measure the level of development of a country’s steel industry depends not only on the quantity but also on the variety and quality. In the recent 10 years, some gratifying changes have taken place in the structure of China’s steel products. The output of plate and tube increased more than the increase of steel output, accounting for 36% of the total amount of steel (plate-tube ratio); energy, transportation , Raw materials and other basic needs of the industrial sector
