Abstract
PURPOSE: To produce a titled clad steel plate with good productivity by annealing press-contact plates press-contacted with an Al (alloy) plate on the surface of a mild steel plate and finish rolling the resultant clad plate then annealing the same after softening.
CONSTITUTION: A plate of Al or Al alloy is superposed on at least one side of a mild steel plate, and the laminated plates thereof are rolled to be press-contacted. The resultant press-contact plates are annealed under the conditions under which the recrystallization softening of the steel plate layer does not occur substantially and under which the recrystallization softening of Al or Al alloy takes place, so that the mutual diffusion of the core material and the skin material in the press-contact layers is progressed. Next, the resultant clad plate is subjected to finish rolling under ≥30% draft, whereby the final thickness of the clad steel plate is controlled. Thence, the clad steel plate is annealed under the conditions under which the recrystallization softening of the steel plate layer takes place.
