一般钢铁行业生产1吨钢铁,往往需要3倍的原材料物资保障与消耗,根据这一比例关系,考虑到钢铁行业原材料与钢铁成品运输,中国钢铁行业总物资运输量往往是钢铁总产量的4-5倍以上经过六十多年的发展,中国钢铁工业取得了巨大成就,已经成为世界钢产量第一的钢铁大国。2011年中国粗钢产量达6.83亿吨,比上年增长7.3%,生产钢材8.8258(含重复材)亿吨,增长9.9%。生产铁矿石产量达13.2694亿吨,比2010年增长27.15%。2011年中国累计进口铁矿石6.86亿t, In general, the steel industry produces 1 ton of steel and often needs 3 times the raw material supply and consumption. According to this proportion, considering the raw materials and finished steel products shipped in the steel industry, the total amount of domestic steel and steel industry is usually 4- More than five times After 60 years of development, China’s steel industry has made great achievements and has become the world’s largest steel producer with the largest steel output in the world. In 2011, China’s crude steel output reached 683 million tons, an increase of 7.3% over the previous year and 8.8258 million tons of steel products (including repeat materials), an increase of 9.9%. The output of iron ore production reached 1,326.94 million tons, an increase of 27.15% over 2010. In 2011, China imported 686 million tons of iron ore,
