Abstract:
Process for producing a cold-rolled strip or sheet of steel with good deforming properties and a bake-hardening potential after a subsequent deforming and for a subsequent temperature treatment, comprising the steps of:hot rolling, coiling, cold rolling and recrystallizing annealing a strip of steel, wherein the recrystallizing annealing is carried out in a bell-shaped furnace, the coiled strip is cooled to &lE;150Â° C. after the recrystallizing annealing, the strip is uncoiled and heated to a temperature T of 200Â° C.&lE;T&lE;A1, briefly annealed at the temperature T for a period of &lE;20 minutes and then cooled from said temperature T at a cooling rate of &gE;1Â° C./s.
