FACT SHEET Steel and raw materials

materials with iron ore exports growing from about 150 Mt to 800 Mt. Coal and coke Coking coal is a key raw material in steel production. As iron occurs only as iron oxides in the earth’s crust, the ores must be converted, or ‘reduced’, using carbon. The primary source of this carbon is coking coal.

RAW MATERIALS worldsteel

Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of recycled steel to produce about 1.7 billion tonnes of crude steel. Recycled steel (sometimes called scrap steel) is one of the industry’s most important raw materials.

Raw materials used in making Iron and steel Studentlesson

Iron OreCokeLimestoneSinterIron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e an iron content if less than 20%. Ores vary considerably in form and composition from one source to another. Some ores are naturally being found as very hard rock, some as granular masses and some as loose earthy materials and with colo在studentlesson上查看更多信息发布日期: Sep 10, 2019
