Aluminium plate manufacturer hot rolling and cold rolling differences

Edit:admin001 Date: 2019-09-25 14:46
Aluminium plate manufacturer introduce the definition of aluminium plate
According to the aluminium plate manufacturer, the aluminium plate refers to an aluminum material having a thickness of 0.2 mm or more and 500 mm or less, a width of 200 mm or more, and a length of 16 m or less.
Aluminium plate manufacturer introduce the definition of hot rolling and cold rolling
According to the aluminium plate manufacturer, from the metal point of view, the rolling below the crystallization temperature is cold rolling. Hot rolling is based on slab (essentially continuous casting billet), which is heated and then made of strip by fine rolling mill and finishing mill.
For aluminum plate manufacturer, cold rolling is processed from hot-rolled plate at room temperature. Although the steel plate is heated during the processing, it is called cold rolling. Generally speaking, after a steel billet is being heated, after several rolling passes, it is trimmed and corrected to become a steel plate. This type is called hot rolling. Since it is not annealed, its hardness is very high (hrb is greater than 90), and the machinability is excellent. Only a slightly biased bending process of less than 90 degrees (perpendicular to the winding deflection) can be held.
Aluminum board manufacturer introduce the difference between hot rolling and cold rolling
What is the difference between hot-rolled aluminum plate and cold-rolled aluminum plate? In fact, it is also very simple, and aluminum board manufacturer can answer them. One is heat treated and one is not heat treated. The meaning of the literal understanding is basically the same. The difference between cold rolled aluminum plate and hot rolled aluminum plate of aluminum plate manufacturer is as follows:
1. The aluminium plate manufacturer introduces one of them, the production process is different: cold rolling is processed by a casting machine into a casting roll (8mm thickness) processed by a cold rolling mill, and the hot rolling is an aluminium plate ingot (400-500mm thickness) plus Temperature, rolled by a hot rolling mill at high temperature;
2. The aluminium plate manufacturer introduces the second, the raw material supply is different: the difference between the two is different in the supply of the blank. The hot rolled billet is cast aluminum ingot—heating—rolling into a coil for cold rolling, and the cold rolling billet is casting and rolling—cold rolling Rolling
3. Aluminium plate manufacturer introduced the third, the performance is different: hot-rolled aluminium plate surface quality is good, mechanical properties and extension properties are strong, oxidation effect is good, while processing aluminum wafers are generally processed from aluminum, naturally also affected by aluminium plate performance Impact;
4. Aluminium plate manufacturer introduced four, different uses, cold-rolled aluminium plate is mostly used in molds, hot-rolled aluminium plate is suitable for stamping and stretching.
Mingtai Aluminum produces hot-rolled aluminum plate, including 1060 aluminum plate and 3003 aluminum plate. The width can reach 2650mm, and the price is affordable. Welcome to consult.
