随着全球化商品化经济的发展,我国的钢铁工业如脱缰野马,十年来有了成十倍的腾飞。到21世纪的前十年,达到了年产六亿吨,约占世界钢产量的一半左右。其背景是:在资源上利用了南半球得天独厚的优质富铁矿;在技术上采用了大高炉——大转炉——连续浇铸的方法。但是低磷的富铁矿石块矿的价格很快就从18美元/吨上涨到180美元/吨,目前约在140-160美元/吨之间,致使我国钢铁工业出现了全行业的低利润局面。目前我国钢铁工业的主要技术路线是大高炉和精
With the development of a globalized commercial economy, China’s steel industry, such as the wild horse, has taken off tenfold in a decade. By the first decade of the 21st century, it has reached an annual output of 600 million tons, accounting for about half of the world’s steel output. Its background is: the use of resources in the southern hemisphere unique rich high-quality iron ore; technically using a large blast furnace - converter - continuous casting method. However, the price of low phosphorus iron ore ore lumps quickly rose from 18 US dollars / ton to 180 US dollars / ton, currently about 140-160 US dollars / ton, resulting in China’s steel industry has emerged in the entire industry, low profits situation. At present, the main technical route of China’s steel industry is large blast furnace and fine
