Abstract (en)
[origin: EP0310376A2] A process for rolling a clad steel satisfactorily reduces the adverse influence of the difference of the deformation resistance of the metal layers composing the clad steel and thereby improves the yield of the rolling process. The rolling process for clad steel includes a step pre-form rolling for a length of 20% to 80% of the overall length of the clad steel. After pre-forming rolling, reduction rolling is performed at a draft substantially equal to or greater than the draft of the pre-form rolling. According to the invention, pre-form rolling process and reduction rolling process are performed for at least two passes.
