本文扼要论述电炉节能、高效炼钢工艺。从磷分配比的计算表明,熔化期比氧化期渣的脱磷能力大2—3倍;氢平衡计算表明,脱氢速度与钢液中氢含量的平方成正比,也与脱碳速度成正比;考虑到溶池在脱气的同时还有吸气过程,在一定的蒸汽分压和脱碳速度条件下,存在一定的最小含氢量限度,所以过大的脱碳量并无实际意义。
This article briefly discusses the electric furnace energy efficient steelmaking process. Calculated from the phosphorus distribution ratio, the melting period is 2-3 times larger than the dephosphorization capacity of the oxidation stage slag. The hydrogen balance calculation shows that the dehydrogenation rate is proportional to the square of the hydrogen content in the molten steel and also to the decarburization rate Taking into account the degassing tank at the same time there are inspiratory process, at a certain steam partial pressure and decarburization speed conditions, there is a certain minimum hydrogen content limit, so excessive decarburization is of no practical significance.
