日本千叶钢厂6号高炉在原有产量的基础上,为向3号发电站提供足够的高炉煤气,采用高焦比生产炼钢生铁,通过调整风口前吸热量、物料分布、鼓风量,防止铁水中[Si]含量和热损耗上升。操作结果,焦碳能量转换效率达到70～80%。高焦比一般是以提高高炉内热量为目的,或在生产铸造生铁时补充铁水中的[Si]还原热。而6号高炉的高焦比操作则是为了在提高焦碳能量转变效率的基础上,产生更
On the basis of the original output, the No.6 blast furnace at Chiba Plant of Japan provided blast furnace gas to No.3 power station and produced steel-making pig iron with high coke ratio. By adjusting the heat absorption, material distribution and blast volume before the tuyere, Prevent [Si] content and heat loss in hot metal from rising. Operating results, coke energy conversion efficiency of 70 to 80%. High coke ratio is generally based on the purpose of raising the heat in the blast furnace or to replenish the [Si] reduction heat in molten iron when producing pig iron. However, the high coke ratio operation of No.6 blast furnace is based on the increase of coke energy conversion efficiency, resulting in more
