碱性电弧炉传统冶炼工艺的还原期,钢液要在白渣下进行长时间扩散脱氧。这种工艺的主要缺点是:耗电量高,钢液吸气,炉衬寿命低,造渣材料消耗多等。因此,缩短、甚至完全取消还原期是当务之急。所谓碱性电弧炉单渣炼钢法,就是取消传统冶炼工艺的还原期扩散脱氧,在单一的 Alkaline arc furnace reduction period of the traditional smelting process, the molten steel to be in a long time under the white residue deoxidation. The main drawbacks of this process are: high power consumption, liquid steel suction, lining life is low, slagging material consumption and more. Therefore, to shorten, or even completely cancel the restoration phase is a priority. The so-called alkaline arc furnace single slag steelmaking method is to cancel the reduction of the traditional smelting process of diffusion deoxidation, in a single
