1. Different usage: cold-rolled aluminium plates are mostly used for moulds, and hot-rolled aluminium plates are suitable for stamping and drawing.
2. Different properties: the surface quality of hot-rolled aluminium plates is good, and the mechanical properties and ductility are strong, and the oxidation effect is good. At the same time, the processed aluminium circles are generally processed from aluminium plates, which are naturally affected by the properties of aluminium plates.
3. The supply of raw materials is different: The hot-rolled billet is vertically cast into billet-heated-rolled into coils for cold rolling, and the cold-rolled billet is cast-rolled coil-continuous casting rolling.
4. The production process is different: cold rolling is processed by a casting machine into cast rolls (8mm thickness) and processed by a cold rolling machine, while hot rolling is heated by an aluminium ingot (400-500mm thickness), which is heated at high temperatures, rolled by the hot rolling mill.
