Rolling method and device for 8CrV saw blade steel

The invention relates to the technical field of smelting and steel rolling, in particular to a rolling method and device for 8CrV saw blade steel. The rolling method comprises the following steps of selecting prearranged 8CrV saw blade steel with the thickness of 110 to 120 mm; rolling the prearranged 8CrV saw blade steel for at most 8 passes by adopting manual procedures of a single stand, and after completing the rolling, increasing the width and the length of a formed steel plate, wherein in the last pass of rolling, the rolling reduction of the last pass is controlled to be 0.45 to 0.65 mmaccording to the difference being 0-0.01 between the unit crown of the last pass and that of the pass prior to the last pass. When high-strength very thin 8CrV saw blade steel with the thickness of 5to 5.5 mm is rolled, the rolling process is more stable, production accidents such as waves, edge cambers, scraping and pulling and misroll of the steel plate are avoided, and a rolled piece can be smoothly rolled. 本发明涉及冶炼轧钢技
