我国是铁矿资源丰富的国家铁矿石是生产钢铁的基本原料。我国早在五千年前就已开采利用铁矿石,公元一世纪左右就建造了和现代高炉相似的炼铁炉,比欧洲人开始炼铁的时间大约早一千五百年。1856年世界上出现了第一批贝氏转炉,开始用焦炭炼钢。二十世纪炼钢技术高度发展,开始生产特殊钢。铁和铁制品不仅在日常生活中有着极广泛的用途,而且在现代化工业建设中竟占全部原材料的70%。因此,人们常把一个国家钢铁的年产量视为工业发展水平的主要标志。我国是世界上铁矿资源比较丰富的国家之一。目 China is a country with rich iron ore resources. Iron ore is the basic raw material for steel production. China had mined and used iron ore as early as 5,000 years ago. In the first century or so AD, it had built a similar ironmaking furnace to a modern one, which was about 1,500 years earlier than Europeans began to make iron. In 1856, the first batch of Bainer’s converters appeared in the world and began to use coke to make steel. In the 20th century, steelmaking technology was highly developed and special steel production began. Iron and iron products not only have a wide range of uses in daily life, but also account for 70% of all raw materials in modern industrial construction. Therefore, people often regard the annual output of a country’s steel as the main indicator of the level of industrial development. China is one of the countries with rich iron ore resources in the world. Head
