"In general, "rolling" is a process that uses a pair of rolls to form materials. There are two rolling techniques, hotrolling and cold rollforming based on the temperature of the metal being used. If the temperature is above the crystallization temperature of metal, the process is called hotrolling; otherwise it is called coldrolling.

Hot rolling is one of the most important manufacturing processes for flat rolled aluminium alloys as it allows the economical reduction of the DCcast slab to thin slab and sheet products. From an energy efficiency perspective, it is more economical to develop near net shape casting processes such as twin roll and twin belt casting, which can cast starting strips of 6–3 mm and 12–20 mm ...

Cold rolled aluminum plate is processed by hotrolled aluminum plate at room temperature and is continuously colddeformed by hot rolling. Its mechanical properties are relatively poor and the hardness is too high, so the cold rolled aluminum plate is mostly used in molds. Hot rolled aluminum plate is better for deep drawing and bending performance, so it is suitable for deep processing.

Hot Rolling : Hot rolling uses large pieces of metal, such as slabs or steel billets, and heats them above their recrystallization temperature. The metal pieces are then deformed between rollers creating thin cross sections. These cross sections are thinner than those formed by cold rolling processes with the same number of stages. Hot rolling also reduces the average grain size of metal but ...
