为使电炉炼钢提高生产率和生产成本达到最佳,新的工艺方法不断取得进一步发展,如泡沫炉渣的使用、炉底出钢和预留钢水操作法、炉底喷射和炉料的高温预热。这些方法的发展已导致了现代化电弧炉设计应装备有水冷栅板、燃烧器、控制器,使用高功率因数的系列电抗UHP变压器和减少电流损失的“热臂”以及简化的维修保养装置。 In order to achieve the best EAF production and production costs to achieve the best, new processes continue to make further progress, such as the use of foam slag, the furnace bottom of the steel and the reserve method of operation, bottom injection and high temperature preheat charge. The development of these methods has led to the design of modern electric arc furnaces to be equipped with water-cooled grids, burners, controllers, a series of reactive UHP transformers with high power factor, a “hot boom” to reduce current losses, and simplified service and maintenance.
