Abstract

PURPOSE:To manufacture the steel strip with stable quality without causing deterioration in the steel material, by suitably setting the amount of strain of the steel strip due to the hearth roll, at the super aging treatment in the continuous annealing process. CONSTITUTION:At the super aging treatment in the continuous annealing furnace, the amount of strain of the steel strip 2 due to the hearth roll 1 is controlled so as to satisfy the formula. In the formula, N is the number of hearth rolls, D is the diameter mm of hearth roll, (t) is the thickness mm of steel strip, T is the line tension kg/mm<2> per unit breadth of the steel strip, Y is the Young's modulus kg/mm<2> of the steel strip at the temperature of super aging treatment, and sigmaYP is the yield stress kg/mm<2> of steel strip at the temperature of super aging treatment.
