Methods for heating of steel plates and apparatus for carrying out the method

A method for heating a board or a pre-formed sheet steel component for the purpose of hot forming and / or quenching, the heating being at least in partial areas carried out to a temperature above AC3, wherein the heating of the board is carried out as rapid heating and for this purpose the circuit board in a first zone with an average heating rate of> 25 K / s to about 600 ° C and above this temperature, with an average heating rate of> 10 K / s to a maximum of AC3 temperature is heated and is then transferred to a second zone in which the first zone preheated board is heated at least in partial areas to temperatures above AC3, wherein the heating rate in the second zone is> 10 K / s.
