Abstract

A method and an apparatus for continuously annealing extra-low carbon steels are disclosed. The apparatus for practising the method comprises a heating zone, a temperature regulating zone having a large heating capacity per unit length of steel sheet and a good response, a rapid cooling zone and a final cooling zone.
