product description

Hot rolling generally refers to rolling in which the metal is carried out above the crystallization temperature. Compared with ordinary cast-rolled products, hot-rolled aluminum sheets have the characteristics of good surface quality, strong mechanical properties and elongation properties, and good oxidation effect. The hot-rolled aluminum sheet produced by Shengming Aluminum not only has a smoother surface, deep drawing and oxidation effect, but also has a finished product width of up to 2650mm. At present, the hot-rolled aluminum sheets produced by Shengming Aluminum are widely used in wide-format curtain wall panels, automobiles, ships, busbars, silos, stampings, molds and other fields.

The difference between hot rolled aluminum sheet and cast aluminum sheet (also known as cold rolled aluminum sheet):

Cold-rolled aluminum sheets are also called cast-rolled aluminum sheets. The difference between cold-rolled aluminum sheets and hot-rolled aluminum sheets is in terms of price, billet supply, production process, performance, use, and finished products.

1. Price: The cold rolled aluminum sheet is simple in process and the price is cheaper than the hot rolled aluminum sheet.

2. The billet supply is different: the difference between the two is different in the billet supply.

Hot rolled material: aluminum ingot--melting and casting into flat ingot--milling surface--homogeneous annealing--hot rolling into strip

Casting and rolling: aluminum ingots - smelting - rolling into strips by a casting mill.

Compared with casting, the production efficiency of castings is high, but defects such as composition segregation and inclusion are not easy to solve, and the quality is not as good as hot rolling;

3, the production process is different: cold rolling is processed by a casting mill into a cast roll (8mm thickness) processed by a cold rolling mill, while hot rolling is an aluminum plate ingot (400-500mm thickness) heating, heat at high temperature Rolling mill rolling;

4. Different performance: the surface quality of hot-rolled aluminum sheet is good, and the mechanical properties and elongation properties are strong, and the oxidation effect is good;

5. Different uses, cold-rolled aluminum sheets are mostly used in molds, and hot-rolled aluminum sheets are suitable for stamping and stretching.

6. Differences in finished products: Generally, the elongation of cold rolled products is lower than that of hot rolled products.
