摘要

This article presents the hot rolling process of a substrate for the production of cold-rolled hot-dip galvanized steel with an inverse temperature gradient using a continuous wide strip mill 2000. The average acceleration of the main part of the strip was increased by 60% relative to the acceleration under the standard mode, which ensures a constant finishing temperature. The physical and mechanical properties of samples collected along the length of the strip were found to comply with the requirements for the strength and plastic characteristics of metals outlined in normative documentation. We established that the hot rolling mode with increased acceleration in a finishing train results in a reduction of machine time of 3–11%, depending on the unit size of the processed metal.
