Abstract: A method for setting a roll gap of sinusoidal corrugated rolling for a metal composite plate includes steps of: determining entrance thicknesses, exit thicknesses, a width, and a rolling temperature of a difficult-to-deform metal slab and an easy-to-deform metal slab; detecting a roll speed and an entrance speed of a metal composite slab, obtaining a roll radius and friction factors; determining parameters of a sinusoidal corrugating roll and a quantity of complete sinusoidal corrugations on the sinusoidal corrugating roll; then calculating a time required for a complete corrugated rolling; calculating a rolling force at any time during the sinusoidal corrugated rolling of the metal composite plate; and calculating the roll gap S of the corrugated rolling at any time according to the rolling force F, and configuring a rolling mill to have the roll gap S according to an actual rolling schedule before normal production.

Abstract: A hydraulically controlled backing roller includes a mandrel, two cover plates which are installed at two ends of the mandrel through screws respectively, and two screwdown gears which are installed at two end portions of the mandrel respectively. The two screwdown gears are engaged with an output rack of a screwdown hydraulic cylinder, multiple saddle ring sets are sleeved on the mandrel at equal intervals, a saddle ring of each of the saddle ring sets is fixed with a frame through a fan-shaped plate, a backing bearing is provided between two adjacent saddle ring sets; an inner eccentric ring of the each of the saddle ring sets is driven to rotate by hydraulic driving, so that the mandrel has a deflection deformation, and the deflection deformation is transmitted to other adjacent rollers through the backing bearing.
