Method for setting roll gap of sinusoidal corrugated rolling for metal composite plate

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.

Method and device for guiding and centering a metal rolling stock in a rolling mill

A method and a device for guiding and centering a metallic rolling stock in a rolling mill having at least one assembly that is arranged in a rolling line and at least one rolling mill stand for shaping the rolling stock are disclosed. The method includes the use of lateral guide means, which exert a lateral force onto the moving rolling stock at different locations of the rolling line, wherein the method further includes the process of centering the inflow of the rolling stock ahead of a first assembly and/or ahead of a first rolling mill stand of the rolling mill using first lateral guide means and the process of aligning rolling stock downstream transversely to the rolling line using second lateral guide means, wherein the process of centering the inflow includes a funnel-shaped, flat guiding of the rolling stock and a point-shaped guiding of the rolling stock.
