Document Type and Number:
Japanese Patent JP7428868
Kind Code:
B2
Abstract:
To accurately predict an extraction temperature of a metal piece in a heating furnace.SOLUTION: In an extraction temperature prediction device 100, an input section 101 accepts input of the characteristic quantities of a target steel slab and the characteristic quantities of each seven steel slabs before and after the target steel slab. The characteristic quantities of the steel slab are target extraction temperature, material, size (length, width, thickness), charging temperature, retention temperature, and retention time. A prediction model holding section 102 holds a prediction model by machine learning. In the prediction model, explanatory variables are the characteristic quantities of one steel slab and the characteristic quantities of each seven steel slabs before and after one steel slab, and an objective variable is extraction temperature of one steel slab. A prediction section 103 uses the prediction model held by the prediction model holding section 102 to predict the extraction temperature of the target steel slab based on the characteristic quantities of the target steel slab and the characteristic quantities of each seven steel slabs before and after the target steel slabs input to the input section 101.SELECTED DRAWING: Figure 1
