高炉透气性指数是国内外近来采用的一个新的高炉操作参数。它是高炉每分钟的入炉风量(Q)与当时炉内全压差(ΔP)的比值(Q/(ΔP))。这个比值对于判断和控制高炉的顺行有积极的意义。 我们七三炼铁五高炉学工小组的同学,在鞍钢炼铁厂学工劳动期间,遵照毛主席“教育要革命”的教导,在工人师傅、技术人员的帮助与指导下,试分析了高炉透气性指数与高炉 The blast furnace permeability index is a new blast furnace operating parameter recently adopted both at home and abroad. It is the blast furnace per minute into the furnace air volume (Q) and then the total pressure difference (ΔP) ratio (Q / (ΔP)). This ratio has a positive meaning for judging and controlling the blast furnace. During the labors of Anshan Iron and Steel Institute, we, under the guidance of Chairman Mao’s “Education to Revolution”, assisted and instructed by the workers and technicians, tried to analyze the blast furnace Breathability index and blast furnace
