Abstract

In continuous steel sheet annealing equipment which is configured of a heating zone a soaking zone and a cooling zone two or more induction heaters are disposed in series in the first half of the heating zone and either a non heating section or a gradually heating section having a heating rate higher than 0 ºC/s but not higher than 10 ºC/s is disposed over a length of 1-30 m in the region which lies between the two or more induction heaters and in which the steel sheet has a temperature of 250-600ºC. Due to such rapidly heating device in the heating zone even when the steel sheet is rapidly heated at a heating rate of 50 ºC/s or higher the temperature distribution within the steel sheet is made even. Thus improvements in quality with respect to steel sheet shape magnetic properties etc. are rendered possible.
