全世界90%左右的生铁是喷吹燃料的高炉生产的。由于各国资源状况不同,高炉喷吹燃料也有所差别。一般说来,西欧和日本主要是喷油,苏联主要是喷天然气,美国既喷油又喷天然气。1973年石油危机后,由于石油价格不断上涨,近年来各产钢国家都在积极开发代用燃料,向所谓无油化钢铁企业发展。美国1980年提出在15年内做到钢铁工业完全用煤作喷吹燃料(现在仍喷重油、煤焦油和天然气),代替油和天然气,以美国
About 90% of the world’s pig iron is produced by blast furnaces that blow fuel. Due to the different resources of different countries, blast furnace fuel is also different. Generally speaking, Western Europe and Japan are mainly fuel injection, the Soviet Union is mainly natural gas injection, the United States both fuel injection and natural gas. After the oil crisis of 1973, due to rising oil prices, all steel producing countries in recent years are actively developing alternative fuels to the so-called oil-free steel enterprises. The United States proposed in 1980 that within 15 years the steel industry should use coal as fuel for jet fuel (it still burns heavy oil, coal tar and natural gas) instead of oil and natural gas and the United States
