摘要
PURPOSE:To simply detect and grasp the temp. conditions in a blast furnace in a proper and accurate manner by applying a method for controlling the distribution of temp. in a blast furnace according to the rate of utilization of gaseous hydrogen in the furnace top. CONSTITUTION:The amount of H2 in gas discharged from the top of a blast furnace is measured and the rate of utilization of gaseous hydrogen in the furnace is calculated by the formula. When the rate of utilization of gaseous hydrogen lowers to =50%, the distribution of temp. in the furnace is controlled by changing the distribution of charge and/or the level of heat.
