ABSTRACT:
A steel strip continuous annealing apparatus comprising: a steel strip feeder; a heating-soaking zone for heating and soaking a steel strip at a predetermined temperature; a first cooling zone for rapidly cooling the steel strip at a predetermined cooling rate; a second cooling zone for slowly cooling the steel strip or holding same at a predetermined temperature; a third cooling zone for cooling the steel strip to substantially room temperature; and a steel strip carryout device; wherein the first cooling zone incorporates therein forcible cooling means, the second cooling zone incorporates therein hot-cold change-over means and the third cooling zone incorporates therein forcible cooling means, while said steel strip continuous annealing apparatus further comprises: means for directly bypassing the steel strip from the heating-soaking zone through a first bypass passageway to the second cooling zone; and means for directly bypassing the steel strip from the first cooling zone through a second bypass passageway to the steel strip carry-out device; so that the steel strips different in dimensions and required heat cycle can be efficiently annealed.
