鞍钢二炼钢厂10号平炉的广大职工,为了缩短平炉冶炼时间,多炼钢,他们在鞍钢钢研所的协助下,采用平炉吹氧炼钢新方法。过去沿用的老方法是先往炉内加废钢、白灰、矿石、铁水,然后吹氧冶炼。1974年11月份他们采用了先加矿石、白灰、铁水,然后进行吹氧,在吹氧的过程中,边吹氧边加废钢,废钢的加入速度要使铁水保持在1550～1600℃为
In order to shorten the open hearth smelting time and increase the number of steelmaking operations, the majority of staff and workers of No. 10 hearth furnace at Anshan Iron and Steel II Steelmaking Plant adopted a new method of blast furnace oxygen blowing steel with the help of Ansteel Steel Research Institute. The old method used in the past is to go to the furnace plus scrap, lime, ore, hot metal, then oxygen blowing smelting. November 1974 they used the first added ore, lime, hot metal, and then oxygen, blowing oxygen in the process of blowing oxygen while adding scrap, scrap steel to join the speed of the molten iron to maintain at 1550 ~ 1600 ℃ for the
