<p>PURPOSE:To improve the quality of a stainless steel strip by adjusting the heating temperature of a heating device so that the temperature of the stainless steel strip becomes at a specific temperature at the tandem mill inlet side. CONSTITUTION:In the case of the warm rolling of a stainless steel strip 3, the temperature fall amount of the stainless steel strip 3 located between a heating device 1 and rolling mill 2 is found by a steel strip temperature fall amount computing element 10, based on the transfer speed of the stainless steel strip 3 operated by a steel strip transfer speed computing element 9. From this result, the opening of a damper 8 for the temperature of the stainless steel strip 3 becoming a specific temperature at the inlet side of a tandem rolling mill 2 is found by a damper opening computing element 11 and this opening is set on the damper 8. Consequently, the steel strip temperature of the tandem rolling mill 2 inlet side can be held at the specific temperature even in the case of the steel strip transfer speed being varied and it is possible to improve the quality of the stainless steel strip 3.</p> |
