Aluminum plate manufacturers should adopt casting rolling (commonly known as cold rolling) and hot rolling (regardless of hot rolling and die casting, the final product must be cold rolling) 1. Rolling plate (i.e. cold rolling steel plate) uses aluminum ingot and other raw materials to melt. Aluminum water flows directly into the two rollers to roll the required aluminum billet (usually about 8 mm aluminum coil). After cold rolling, you want the thickness of aluminum plate, So water ripples are easy to appear.
The raw materials such as hot-rolled plate are aluminum smelting, and aluminum water flows into the square mold to make aluminum billet (i.e. casting billet). Deep well ingot) is usually made of aluminum billet thickness, fiber drawing countercurrent or millimeter thickness (thickness). After the aluminum billet is heated in the oven for hours (also known as homogenization treatment) through 56 Baidu. After the surface of the aircraft, after the hot rolling and cold rolling process, it is much more complicated, so a more stable multi roll casting aluminum is produced, much better. (in terms of cost, more uniform treatment, while heating oil is burning, there will be large-scale hot rolling machines, etc., with much higher cost.) ask why there is no water mark on the aluminum plate before anodizing, and why does the water mark appear on the aluminum plate after anodizing?
Why there is no water ripple on the anode before the production process of aluminum plate? Because whether the hot-rolled steel plate or cast rolling plate passes the cold rolling? At last, the water ripple is the grinding wheel of two data of rolling plate. The previously unprocessed meat can't be seen, but you can see it in the anode alkali washing and pickling. Now you should see a little. Then if the natural color oxidation becomes obvious, the hard oxidation is more obvious.
