Description

technical field [0001] The invention relates to hot strip rolling technology, in particular to virtual simulation of hot continuous strip rolling process. Background technique [0002] In the production process of hot-rolled strip steel, the billet from continuous casting first needs to be put into the heating furnace for heating. By adjusting the temperature of the heating furnace, it is heated to about 1200 degrees, and then transported to the rough rolling unit for rolling through the conveying roller table. There is a high-pressure water descaling device between the heating furnace and the rough rolling unit. When the strip passes through, it will use high-pressure water to remove most of the oxide scale on the surface of the strip, and then the strip enters the rough rolling unit at a certain threading speed. , the rough rolling unit is generally divided into E1R1 (the first set of vertical rolls and flat rolls) and E2R2 (the second set of vertical rolls and flat rolls)...
