Method of regulation of the temperature of the flat metal products subjected to rolling, in particular in order to remove the traces black, and a device for the implementation of this

摘要

Process and device for regulating the temperature of the flat metal products beforehand reheated of such a manner that is not homogenous in a furnace and then subjected to a hot rolling. The products are reheated by an induction heating device m is increasing after having undergone a plurality of rolling passes, and n4 at each instant, the value of the heating power furnished a part of the product which is located at the time was in the zone of action of the reheating device m, as a function of the local temperature of said part of the product, the speed of defilement instant of the product and a temperature desired to said part of the product, this temperature desired being defined by a profile desire and to predetermined of temperature in the longitudinal direction of the product.
