  • Process for preventing transverse displacement of metal strip
    Patent number: 4773949
    Abstract: A process for preventing transverse displacement of metal strip comprises correcting a shape of metal strip into flat form prior to the travel of the metal strip into a continuous annealing furnace when continuously annealing the metal strip in the furnace under a condition of LSD.gtoreq.100 (representing a product of line speed and strip gauge).

  • Steel strip continuous annealing apparatus
    Patent number: 4363471
    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 passage
