Abstract (en)
[origin: US4710240A] Cold rolled steel strip is uncoiled, cleaned, and passed into an annealing furnace, wherein the strip is heated to and held at a relatively hot temperature, subsequently quenched, and coiled; after a period of storage the strip passes through the same equipment but now including additional pickling for removing an oxide layer, and the strip passes through the annealing furnace a second time, while operating said annealing furnace for heating to and holding at a lower temperature to obtain aging; thereafter the strip is coiled again.
