1. Price: The cold rolled aluminum sheet with CC materials is simple in process and the price is cheaper than the hot rolled aluminum sheet with the DC materials.
2. The billet supply is different: the difference between the two items 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 caster. Compared with castings, the production efficiency 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 machine into a casting coil (8mm thickness) processed by a cold rolling mill, while hot rolling is an aluminum ingot (400-500mm thickness) heating, at high temperatures Hot 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. At the same time, the processing of aluminum discs is generally processed from aluminum sheets, and naturally the performance of aluminum sheets is also affected;
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 between finished products: Generally, the elongation rate of cold-rolled final products is lower than that of hot-rolled final products. In the case of cast or hot rolled products, the surface of the product in the hot rolled state is usually brighter.
The difference between the above two is integrated through Baidu network, and there are many similarities, but the previous ones have been supplemented and expected to be adopted. |
