近年来工业发达国家的炼钢电弧炉在以节能和提高钢质量为核心的方针指导下,在装备水平、工艺技术上有10多项重大的改革。本文有选择地时炉容量大型化,炉容量与变压器容量的匹配,电炉烟气预热度钢,氧-燃料烧咀,水冷炉壁,水冷复合电极,炉底出钢,计算机控制等八个方面进行了报导,并对今后我国炼钢电弧炉的发展提出了看法。 In recent years, industrialized countries, steel-making electric arc furnace in the energy-saving and improve the quality of steel as the core guideline, at the level of equipment, technology there are more than 10 major reforms. This article has the choice of large furnace capacity, furnace capacity and transformer capacity matching, electric furnace flue gas preheating steel, oxygen - fuel Tsui, water-cooled furnace wall, water-cooled composite electrode, the bottom of the tapping, computer control, eight And made some comments on the future development of EAF in our country.
