1.产量和品种硅铁主要用在炼钢中作为脱氧剂和合金添加剂,也消耗于铸造生产,前者约占钢铁工业中总耗量的60—70%,后者约占30—40%。根据统计资料,1979年世界硅铁的总产量约为370万吨。近年世界各国硅铁产量列于表Ⅰ—1。从表Ⅰ—1可以看出,近几年美国、西德、苏联的硅铁产量变化不大,挪威、西班牙、加拿大和南非等国产量增多,而日本在1981年只生产了24万吨左右。
1. Yield and Variety Ferrosilicon is mainly used in steelmaking as a deoxidizer and an alloy additive, which is also consumed in foundry production. The former accounts for about 60-70% of the total consumption in the steel industry, while the latter accounts for 30-40%. According to statistics, the world’s ferrosilicon production in 1979 was about 3.7 million tons. Ferrosilicon production in various countries in the world in recent years is shown in Table I-1. As can be seen from Table I-1, the output of ferrosilicon in the United States, West Germany and the Soviet Union has not changed much in recent years. The output of Norway, Spain, Canada, South Africa and other countries has increased. Only Japan produced about 240,000 tons in 1981 .
