METHOD FOR REGULATING TEMPERATURE OF FURANCE IN BLAST FURNACE PROCESS

摘要

PURPOSE: A method for controlling the temperature of furnace heat in a blast furnace process is provided to exactly and rapidly control the amount of reducing agents blowing in a furnace according to the change of the furnace heat. CONSTITUTION: A method for controlling the temperature of furnace heat in a blast furnace process comprises following steps. A calculation sheet on a furnace heat influence, which indicates a correction value for the furnace heat influence, a reducing agent rate according to the temperature and moisture ratio of cokes is prepared(S101). The temperature and moisture ratio of the cokes are measured(S102). The correction value of the reducing agent rate is calculated using The temperature and moisture ratio of the cokes(S103). The corrected reducing agent rate is calculated using the obtained reducing agent rate and the current reducing agent rate(S104). The amount of the reducing agents, corresponding to the corrected reducing agent rate is putted into the furnace(S110).
