Abstract
A method and an apparatus for carrying out the annealing step of a galvannealing process in which strips and sheets, particularly of steel, are subjected after galvanizing to an annealing step by heating the coated material and subsequently holding at final annealing temperature, wherein, during annealing, the heating step is interrupted by at least one additional holding step and, thus, a stepwise increase of the temperature over time is adjusted.
