Abstract (en)
[origin: WO2023006731A1] The invention relates to a method for the hot rolling of metal rolling material by means of a plurality of rolling devices disposed in a rolling line, the method comprising the providing of semifinished product having a thickness of greater than or equal to 150 mm as rolling material, the rolling material being rolled in the rolling line from a first large initial cross-section to a relatively smaller target cross-section by incremental decrease in thickness, characterized in that the decrease in thickness from the initial cross-section to the target cross-section is achieved exclusively by means of a single rolling device or by means of a plurality of similar rolling devices of a single rolling stand type. The invention also relates to a hot-rolling mill for carrying out the method.
