A single-side tower-type roller system based asynchronous rolling mill for rolling an ultra-thin composite strip and a hydraulic system therefor are provided. The mill includes a machine frame and reel assemblies. An upper roller system assembly and a lower roller system assembly are arranged in the machine frame. A down-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the upper roller system assembly and the lower roller system assembly. A support roller balance assembly is arranged on the machine frame and used to support and balance the upper roller system assembly. The lower roller system assembly includes right and left working rollers. The right working roller is a plain roller. The left working roller is a patterned roller. A left-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the right and left working rollers.

Provided is a method for rolling a strip with a roll stand with at least two work rolls. A rolling gap with a pass line is defined between the work rolls. A control roll is arranged before the rolling gap of the work rolls in the rolling direction, the strip is guided into the rolling gap of the roll stand via the control roll at an entry angle relative to the pass line and the surface structure of the strip is controlled through the selection of the entry angle depending on the positioning of the control roll relative to the pass line. Also provided is an apparatus for rolling a strip with a roll stand having at least two work rolls. A rolling gap with a pass line is defined between the work rolls.

A refractory metal plate is provided. The plate has a center, a thickness, an edge, a top surface and a bottom surface, and has a crystallographic texture (as characterized by through thickness gradient, banding severity; and variation across the plate, for each of the texture components 100//ND and 111//ND, which is substantially uniform throughout the 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.

A rolling mill has a rolling stand (1) in which a flat rolled product (2) composed of metal is rolled. A sensor device (6), which detects at least one measured variable (M) characteristic of a material property of the flat rolled product (2), is arranged upstream and/or downstream of the rolling stand (1). The material property can be, in particular, an electromagnetic property or a mechanical property of the rolled product (2). The sensor device (6) transfers the detected measured variable (M) to a control device (9) for the rolling mill. Taking into account the measured variable (M), the control device (9) determines a control value (A) for the rolling stand (1). The control of the rolling stand (1) influences the material property of the flat rolled product (2). The control value (A) is a ratio of the peripheral speeds (vO, vU) at which the upper and the lower working rolls (3, 4) of the rolling stand (1) rotate.

A device for manufacturing a lithium band including a rolling area including two rolling cylinders, a feed-in area including a device for feeding in the rolling area with a lithium band with a first thickness, a device for feeding in two films interposed between the lithium band with a first thickness and a rolling cylinder, and a storage area including a device for collecting a lithium band having a second thickness. The lithium band with a second thickness is tensioned and rolls ensure a separation of each film off the surface of one of the rolling cylinders in a separation area located beyond a horizontal plane passing through the axis of rotation of the rolling cylinder and located opposite to the other rolling cylinder.
