摘要： A transverse vibration rolling system and a preparation method for a double-layer metal composite ultra-thin strip relate to a technical field of rolling, which solve problems including poor rolling and bonding effects, low geometric accuracy, and poor plate shape quality of metal composite ultra-thin strips. The transverse vibration rolling system includes: a first roll, a second roll, a first hydraulic vibrator, a second hydraulic vibrator, a first hydraulic motor, a second hydraulic motor, a check valve, a first hydraulic pump, a first overflow valve, an oil tank, a controller, a second overflow valve, a second hydraulic pump, an electromagnetic reversing valve, a first speed control valve, and a second speed control valve. The transverse vibration of the rolls of the present invention can apply transverse shearing force on the ultra-thin metal strips during the bond rolling.

摘要： A device and a method for rolling a metal strip. A distance of the upper/lower backup roll at at least one point thereof from a predetermined upper/lower reference point is measured by an upper/lower sensor and the measured values of the sensors are sent to a control device. A strain of the roll stand is calculated using a mathematical model, taking into account the rolling force generated. By the control device, an absolute value of the roll gap and thus the resulting thickness of the rolling stock is determined by the control device on the basis of the measured positions of the backup rolls and the calculated strain of the roll stand.

摘要： A rolled metal sheet includes an obverse surface and a reverse surface that is a surface located opposite to the obverse surface. At least either one of the obverse surface and the reverse surface is a processing object. A method for manufacturing a metal mask substrate includes reducing a thickness of the rolled metal sheet to 10 μm or less by etching the processing object by 3 μm or more by use of an acidic etching liquid, and roughening the processing object so that the processing object becomes a resist formation surface that has a surface roughness Rz of 0.2 μm or more, thereby obtaining a metal mask sheet.
