Huawei is a leading manufacturer of aluminum sheet sales in China, sincerely at your service! As a professional aluminum sheet supplier, we have rich experience in aluminum processing and manufacturing. There are several typical aluminum sheet metalworking techniques.
1. Hot rolling process
The hot rolling process is gradually evolved from the method of semi-continuous casting, head counting, milling, and then completing the product processing through multiple hot rolling on a single stand. Today's hot rolling mills in the United States are divided into single-stand single-coil, single-stand double-coil and multi-stand, rolling aluminum billets from 600 to 350 mm in thickness to 8 to 2 mm. The product range is: 1XXX, 3XXX, 5XXX, 7XXX, 8XXX series aluminum and aluminum sheet metal for sale. There are many types of hot-rolled Aluminum for Building products with good quality and large output. The aluminum sheet and strip produced by hot rolling accounts for more than 65% of the world's total output, but the investment in hot rolling production lines is large, and the investment of one production line is 150-20 billion yuan, which limits the development of hot rolling technology to a certain extent.
2. Casting and rolling process
The casting and rolling process is a method in which molten metal is directly introduced into the gap between two internal water-cooled rotating rolls, and after crystallization, solidification and deformation, the aluminum strip is pulled from the other side of the rolls. It integrates a series of complex production processes such as casting and rolling, which greatly simplifies the hot rolling production process and opens up a new way for the production of aluminum processing strips. The casting and rolling machine can directly produce aluminum coils with a thickness of 5-12mm from molten aluminum, which greatly reduces the production cost of aluminum sheet metal. However, due to the limitation of the length of the cooling zone and the cooling strength of the casting and rolling mill, the range of materials produced by the casting and rolling process is narrow, the amount of thermal deformation is small, the deep drawability is not good, the foil is easily broken during rolling, and the output is low. These problems limit the development of casting and rolling technology.
3. Continuous casting and rolling process
The method of introducing molten metal into a pair of water-cooled circulating steel belts (including crawler belts), directly casting them into aluminum sheets with a thickness of 20 to 30 mm for sale, and then rolling them into aluminum coils by 1 to 3 racks at the rear is called continuous casting. Casting and rolling process. The range of materials produced by it is close to that of hot rolling, and the product performance is better than that of cast-rolled aluminum sheet, but worse than that of hot-rolled Quality Alloy Aluminum Sheet. The accumulation of subcutaneous inclusions on the upper surface of the billet affects the quality of the processed aluminum sheet products and greatly limits the development of the continuous casting process.
