Problems solved by technology

Although the microstructure and properties of the 3003 aluminum alloy strip produced by this method are good, and its tensile strength, elongation and lug rate can meet the requirements of deep drawing products, the processing technology is complicated and the production cost is high.
And when the hot-rolled billet is smelted, the metal burning loss is 2.5%, the cutting head and tail amount is 6%, and the milling amount is 5.5%. If the waste generated in the ingot casting process and the hot rolling process is considered, the comprehensive yield is only 80%. %, thus also increasing the cost of 3003 aluminum alloy deep drawing products
[0004] At present, there are still 3003 aluminum alloy deep drawing products made by direct casting and rolling blanks. Although the production process of this method is simple and the manufacturing cost is low, the 3003 aluminum alloy produced by the existing casting and rolling method generally has deep drawing properties. Not good, poor appearance quality, easy to crack and other defects, it is difficult to meet the user's requirements for 3003 aluminum alloy deep drawing products
