METHOD FOR DETERMINING OPTIMUM EXTENT OF OPERATION UNDER OPERATIONAL CONDITION DURING OPERATION OF SINTERING APPARATUS

摘要

PURPOSE:To allow a sintering apparatus to rapidly cope with a change in the volume of wind and to stabilize quality by determining the optimum extent of operation with respect to the speed of the pallet or the thickness of a layer from the estimated desired volume of wind in a sintering model based on the operational state of the sintering apparatus such as the measured values of the speed of wind. CONSTITUTION:The measured values of the speed of wind obtd. from wind gauges placed at four or more positions of the wind box section of a Dwight- Lloyd type sintering apparatus or the surface of the apparatus, the speed of the pallet, the thickness of a layer and negative pressure by suction are inputted in a sintering model, the desired volume of wind to be sucked is estimated by calculation, and the optimum extent of operation for attaining the desired volume of wind with respect to the speed of the pallet or the thickness of the layer is determined to control the operational conditions of the sintering machine. Thus, the desired volume of wind is accurately attained in a short time, and quality can be stabilized.
