Problems solved by technology

[0007] The important reason for restricting the application of deformed magnesium alloys is that magnesium alloys have a close-packed hexagonal structure. At room temperature, magnesium alloys have only one set of basal slip systems, and their plastic deformation ability is poor, which often leads to fracture during processing.

Embodiment Construction

[0030] After the magnesium alloy coil to be rolled is confirmed, it is placed on the uncoiler 1 for threading, the strap of the strip is opened, and the uncoiler is started to pass the first deflection pinch roller 2 and the first tension pinch roller 3. Send the strip to the straightening machine 4 for straightening, pass through the second tension pinch roller 5, and enter the online heating device 6, and the heated strip pass through the third tension pinch roller 7, and enter the first thickness gauge 8 to measure the thickness of the incoming material. After passing through the first guide roll 9 and the second guide roll 11, the coil enters the first work roll 12 and the second work roll 13 for asynchronous rolling, and passes through the second guide roll 14 to enter the second The second work roll 13 and the third work roll 15 carry out asynchronous rolling, pass through the third guide roll 16, enter the third work roll 15 and the fourth work roll 17 for asynchronous r...

Abstract

The invention relates to a continuous asynchronous rolling device of a magnesium alloy sheet strip coil and belongs to the field of magnesium alloy materials. The continuous asynchronous rolling device conducts decoiling on the magnesium alloy strip coil through a decoiling device, the magnesium alloy strip coil enters a flattening machine to be flattened through a tension pinch roller and enters a strip coil preheating device through the tension pinch roller after being corrected to be heated to preset temperature, feeding material thickness is measured through a thickness gauge, then the strip coil enters a continuous asynchronous rolling machine for rolling, the rolled strip coil passes through the thickness gauge to measure thickness of a finished product and enters a rolling machine to be rolled through the tension pinch roller, and the whole coiling rolling is achieved after stable rolling tension is finished. The continuous asynchronous rolling device has the advantages of reducing rolling pressure and rolling torque, reducing energy consumption, increasing gate transformation quantity, improving rolling efficiency and the like, thereby being favorable for rolling production of strip coils of magnesium alloy which is hard to deform.

Description

technical field [0001] The invention relates to the field of magnesium alloy materials, in particular to a process and a device for producing magnesium alloy sheet coils with different widths. Background technique [0002] Rolled magnesium alloy sheet, strip and coil products belong to the magnesium alloy deep processing industry, which is a new material industry supported by the state and an encouraged development project. High-performance rolled magnesium alloy strip is the main material for direct production or forming into precision structural parts with multiple functions such as conductivity, heat dissipation, shock absorption, noise prevention, energy saving, and light weight. It is mainly used for the production of electronic information products (such as computers, communications, consumer electronics, etc.) casings, automotive electronic casings, frames, instrument panels, home appliances, and military products, etc. The material has the advantages of high added v...
