Abstract

PURPOSE:To expedite the response of strip temp. by performing forcing in order to correct the calculated value of the rate of transfer of heat between hearth rolls and the strip at the changing of the target temp. and the like of the heating or cooling furnace of a continuous annealing furnace. CONSTITUTION:While a strip 1 is transferred by the revolution of hearth rolls 5 of a continuous annealing furnace 2, it is heated or cooled continuously. At the changing of the target temp., thickness, and speed of the strip 1 of the furnace outlet, the quantity of heat corresponding to the rate of heat transfer between the rolls 5 and the strip 1 is calculated, and in order to correct this, forcing is carried out by using the quantity of heating or cooling. For example, at the changing of the target temp. of the strip 1, C1 is the strip temp. at the zone inlet C2, C2' are the temps. of the rolls 5, C3, C3' are the strip temps. at the zone outlet, C4 is the flow rate of fuel when the effect of the rolls 5 is not considered, and C5 is then forcing rate of the flow rate of fuel when said effect is considered. The C2, C3 and the C2', C3' are respectively the case when the forcing is carried out and when it is not and the time for setting at the target temp. of the strip is improved from about 11min to about 1min.
