采用按流体分布状态和所允许最大热流强度的方法,对鞍钢3200m~3高炉炉缸冷却水需求量进行了计算,并就冷却水流速、水管直径和气隙参数对冷却壁热面温度影响进行了分析。认为鞍钢3 200m~3高炉炉缸冷却壁用φ50mm×6mm水管和1250m~3/h的冷却水量,对冷却强度和系统回路阻损的设计都是偏小的。
According to the distribution of fluid and the maximum allowable heat flux, the demand of cooling water in 3200m ~ 3 blast furnace hearth of Ansteel Iron and Steel Co. Ltd was calculated and the effects of cooling water flow velocity, water pipe diameter and air gap parameters on the hot face temperature of cooling wall were studied analysis. Considering the φ50mm × 6mm water pipes and the 1250m ~ 3 / h cooling water volume of the 3 200m ~ 3 blast furnace hearth cooling towers in Anshan Iron and Steel Co., Ltd., the designs of both the cooling intensity and the system circuit resistance loss are both small.
