一、前言硅铁主要用于炼钢和铸造工业,它是炼钢过程中的脱氧剂与合金元素添加剂。一般生产一吨钢需耗硅铁(含硅75%)5—8公斤,因此,它对钢铁工业的发展起着重要的作用。硅铁生产是一个高耗能项目,我国每年生产硅铁耗电占全国总发电量的1%,占铁合金生产用电量的5%,生产一吨硅铁耗电量为8000—9000kWh,有些企业超过9000 First, the foreword Ferrosilicon is mainly used in steelmaking and foundry industry, it is a deoxidizer and alloying element additives in the steelmaking process. General production of one ton of steel requires ferrosilicon (75% silicon) 5-8 kg, therefore, it plays an important role in the development of the steel industry. Ferrosilicon production is a high-energy-consuming project. China’s annual production of ferrosilicon consumes 1% of the country’s total generating capacity and accounts for 5% of the ferroalloy production. The production of one ton of ferrosilicon consumes 8000-9000 kWh, and some More than 9000 enterprises
