<p>The temperature of stacked, continuously cast metal plates (1) is held at a desired temperature level of more than 1000 degrees C by surrounding the stack with a thermally insulating housing (2) which is surrounded, in turn, by an induction heating coil (3). The coil is supplied with an alternating current of a selected frequency in order to provide a desired penetration depth of the induced flux and by this means to heat the stack only in the vicinity of the cooler outer surfaces and only as necessary and just sufficiently to avoid any heat loss. The thermally enclosed stack and the power supply can be mounted on a wheeled transfer carriage (7) in order to facilitate the delivery of the plates to the next work station, such as a rolling mill, while at the same time maintaining the desired temperature level during transfer. <IMAGE></p> |
