摘要

Method for processing a steel product and product produced using said method.The present invention relates to a method for processing a product of steel.In which the product of steel is passed between a set of cylinders of a chair of a rolling mill so as to laminate the steel product.According to the invention, the cylinders of the chair of the rolling mill have different peripheral speeds so that a cylinder is a cylinder of faster movement and the other cylinder is a cylinder ofSlower motion, and the peripheral speed of the cylinder faster movement is at least 5% higher and the maximum 100% higher than that of the cylinder of slower motion.And the thickness of the product of steel is reduced by at least 15% per pass, and the lamination occurs at a maximum temperature of 1350 198 C.The invention relates also to a product of steel produced using the method, and the use of this product of steel.
