In judging the quality of alloy aluminium plate, we should pay attention to the surface smoothness, but also observe whether the thickness of the aluminum plate is uniform, pinch the plate by hand, feel whether the elasticity and toughness are good. So understanding the production process of aluminium sheet can help you better judge the quality of aluminium sheet plate.
On the other hand, aluminum plate stock has been widely used in the construction industry, especially in decoration building materials. So the aesthetics of perforated aluminum plate is paid more attention. So now more manufacturers are more concerned about the surface aesthetic treatment of aluminium sheets. Generally hydrophilic aluminium foil on the market has good hydrophilicity on the surface, while condensation water remains between heat exchangers.
The basic steps of making aluminium sheet plates are as follows:
1. Aluminum and aluminium alloy sheets and strips are supplied in various grades of soft state and various heat treatment states.
2. Preparing before hot rolling mainly includes quality inspection of ingot, soaking, sawing, milling, aluminium cladding and heating.
3. Milling surface should be carried out when there are defects such as segregation float, slag inclusion, scarring and crack on the surface of aluminium ingot.
4. Hot rolling process includes pass reduction rate, rolling temperature, rolling speed, lubrication and cooling, etc.
