摘要： A method of estimating the properties of a steel product, comprising completing a computation for determining metallurgical phenomena based on information concerning steel ingredients and production conditions in steps from casting to heat treatment to successively determine the state of a metallic structure and estimating the properties of a steel product from the final state of the metallic structure. More specifically, the method comprises the steps of: computing the temperature of a slab based on casting conditions and further completing a computation for the state of the metallic structure after casting based on information concerning the temperature of the slab and steel ingredients; completing a computation for the state of the metallic structure after rolling based on the state of the metallic structure before the rolling and the temperature of the steel product computed from rolling conditions; completing a computation for the state of the metallic structure after cooling based on the state of the metallic structure before the cooling and the temperature of the steel product computed from cooling conditions; and completing a computation for the properties of the steel product based on the final state of the metallic structure. In order to cope with the provision of additional production steps such as reheating, a homogeneous diffusion heat treatment, preliminary rolling, quenching, tempering and normalizing, etc., the method may further comprise the steps of completing a computation for the state of the metallic structure after applying the additional steps based on the state of the metallic structure before applying the additional steps and the conditions for the additional steps.
