摘要

The carbonization end time control method according to the present invention is a carbonization end time control method for controlling carbonization end time in carbonization chambers of a coke furnace in which combustion chambers and carbonization chambers are alternately connected to form a battery, the method being characterized by comprising: a step for finding a relationship formula in which carbonization end time for each carbonization chamber is a target variable, and information pertaining to furnace temperature for each carbonization chamber is an explanatory variable; a step for predicting the carbonization end time for a subsequent round on the basis of the relationship formula and temperature variation trends in furnace temperature in a most recent prescribed period; a step for finding a temperature operation amount for each carbonization chamber so that the predicted carbonization end time for the subsequent round is a preset target carbonization end time; and a step for converting the temperature operation amount for each carbonization chamber to the temperature operation amount for each combustion chamber.
