The process flow of producing aluminum foil blanks by casting and rolling is relatively simple; there is no need to go through complex process steps such as melting ingots, milling, homogenization and hot rolling. Instead, the aluminum melt is poured directly into two rotating casting rollers ( Crystallizer), the solidification and hot rolling processes are completed simultaneously in the casting and rolling area within 2 to 3 seconds, and a plate with a thickness of 4 to 7 mm is obtained. Similar to hot-rolled aluminum foil billets, cast-rolled plates also need to go through a series of cold rolling and intermediate annealing processes, and are finally rolled into 0.3~0.7mm thick plates as aluminum foil billets.
The double-roller casting and rolling method has simple equipment, low total investment, and short production cycle. It eliminates many tedious processes such as milling, homogenization, and hot rolling in the production of hot-rolled plates. Therefore, the casting-rolling method is more suitable for producing aluminum foil blanks. The cost is greatly reduced; however, due to the different cooling methods and hot processing conditions during the production of plates by the double-roll casting and rolling method, the internal structure of the cast-rolled plates mainly has shortcomings such as segregation, uneven structure, and coarse grain structure after annealing, and its quality control It is more difficult, so it is relatively rarely used in high-quality aluminum foil products.
At present, the process of casting and rolling applied to aluminum foil blanks is gradually maturing. More and more companies are beginning to use the casting and rolling process to prolling have become the mainstream front-end process for aluminum foil. Casting and rolling appeared in the 1970s, and the technology is still not perfect.oduce aluminum foil.
In recent years, GNEE has independently developed "casting-rolling-cold rolling short-process green manufacturing technology" and has successfully applied it to high-end products such as double-zero foil and power battery foil. This technology innovates the entire industry chain from composition optimization, smelting process, continuous casting and rolling process and cold rolling/foil rolling process optimization, as well as performance testing and quality control technology. It uses the casting and rolling method instead of the hot rolling method to produce aluminum foil for power batteries. / thin plates, which reduces the production costs of aluminum foil / thin plate manufacturers for power batteries, improves market competitiveness, and to a large extent promotes the development of the domestic battery aluminum processing industry.
