Aluminum Sheets For Sale

2022-03-16

In the production process, the aluminum sheets for sale needs to undergo hot rolling, annealing, various heat treatments, etc. In order to obtain a more flat and smooth aluminum sheet product, it needs to be hot rolled, and it must be fully lubricated. Aluminum sheet lubrication often uses water-based emulsion, which is made up of emulsion and water, and the concentration is slightly lighter when rolling aluminum sheet.

In order to obtain a hot-rolled coil with good flatness, it is necessary to control the shape of the rolling roll gap, adopt the method of hydraulic bending rolls and zone cooling of the roll body, and at the same time, adjust the reduction schedule and rolling speed. In addition, the emulsion sprayed on the roller can not only lubricate, it can also play a role in cooling. The pressure and flow rate of the emulsion at the nozzle must be set in advance to ensure smooth outflow.

Through cold rolling, the aluminum sheets for sale can be made flatter, smoother, and has a uniform thickness and better microstructure and properties. Cold rolling can be performed on a single stand or a continuous rolling mill. Under the conditions that the equipment capacity allows, the lubrication and cooling are good, and the rolled pieces are not cracked, the pass reduction rate is used for cold rolling. The pass reduction rate can make the rolling force of the pass basically the same, so as to ensure that the aluminum sheet with uniform thickness and better flatness is rolled.

Under the condition that there is no edge cracking in each pass, the total cold rolling reduction rate of pure aluminum sheets for sale can reach more than 95%. In the process, two intermediate anneals are also performed. In order to obtain a higher quality aluminum sheet, more complicated processes are required.
