5083 aluminum coil manufacturer analyze the difference between hot rolling and cold rolling
5083 aluminum coil manufacturer, aluminum coil price, the difference between hot rolling and cold rolling
Henan Mingtai Aluminum Co., Ltd. is a professional aluminum coil manufacturer, supplying 1-8 series aluminum sheet aluminum coils, providing aluminum for automobile, light rail/metro/tank/ship, aluminum for mold, aluminum for construction, aluminum for hardware and electrical appliances. , aluminum for electronic products, aluminum for signage, aluminum for packaging containers, aluminum for printing, etc. The products cover various industries and provide the latest aluminum coil price.
For the production of aluminum coils, there are mainly two types of hot rolling and cold rolling. The so-called hot rolling process is rolling above the crystallization temperature of metals and alloys; the cold rolling process is the rolling process below the recrystallization temperature of metals and alloys, although cold deformation, although due to metal deformation heat and friction heat, It can make the temperature of the rolled piece high and has a certain recovery effect, but the main function in the cold rolling process is cold work hardening.

1. The raw material supply is different: the hot-rolled billet is vertically cast into a billet-heating-rolling into a coil for cold rolling, and the cold-rolled billet is a cast-rolled coil-continuous casting and rolling;
2, 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 The hot rolling mill is rolled; therefore, the cold rolling process can obtain a thin strip of sheet material.
3. Different performance: The surface quality of hot-rolled aluminum sheet is good, the mechanical properties and the ductility 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 it is also affected by the performance of aluminum sheets;
4. Different uses: Cold-rolled aluminum sheets are mostly used in molds, and hot-rolled aluminum sheets are suitable for stamping and stretching.
Mingtai Aluminum supplies hot-rolled aluminum sheets and cold-rolled aluminum sheets. It has many models and specifications, and can be customized according to user needs. The annual output is 770,000 tons. Welcome to consult: sales01@mingtai-al.com.
