Title:
鋼片の加熱炉抽出温度予測方法及び加熱炉抽出温度予測装置
Document Type and Number:
Japanese Patent JP7040497
Kind Code:
B2
Abstract:
To more accurately obtain temperature of a billet extracted from a heating furnace.SOLUTION: A method for estimating temperature of a billet extracted from a heating furnace includes: a scale removal step of removing surface scale of a billet S extracted from a heating furnace, a residual scale amount estimation step of estimating amount of a residual scale which remains on a billet surface after scale removal, a temperature measurement step of measuring a surface temperature of the billet S from which the scale is removed after reheating of the surface of the billet is completed, a surface temperature true value estimation step of estimating a surface temperature of a billet surface under residual scale based on the temperature measurement value of billet surface temperature measured in the temperature measurement step and the estimated residual scale amount, and a heating furnace extraction temperature estimation step of calculating a billet surface temperature upon being extracted form the heating furnace based on the surface temperature estimated in the surface temperature true value estimation step.SELECTED DRAWING: Figure 1
