Aluminum strip blank continuous casting and rolling process application


The continuous casting and rolling process of aluminum strip blank is an advanced production process introduced from abroad in the 1980s. Its basic flow is: aluminum ingots → melting furnaces → static furnaces → degassing → filtering → casting nozzles → rolling mills → intermediate units → Winder.


It is characterized by casting and rolling molten aluminum into 6-10mm thick and 650-1400mm wide slabs and winding them, and then directly sending them to the cold rolling mill for finishing rolling. In this way, ingots are omitted in the production process of aluminum strips , Heating, hot rolling, billeting, etc., not only shortened the process of aluminum plate and strip production, greatly reduced engineering construction funds, but also reduced metal burn-out during the production process, saving energy, and at the same time can easily achieve aluminum plates Continuous production of strip. It is used to cold-rolled strip coils of aluminum and aluminum alloys, through the unwinding and cutting head of the unit, trimming, joint sewing, surface cleaning, drying, stretch side bending straightening, board surface inspection, coiling and rectifying processes To obtain flat, clean, uniform color and neat rolled products, suitable for the production of high-quality products that require flat slate, no oil, surface water, paint coating, decoration and compounding.Used for hot rolling or After cold rolling, the aluminum and aluminum alloy strips are cut horizontally or the plates are closed at different lengths.The machine train consists of uncoiling, feeding, cutting head flattening, cutting and waste processing, roll leveling, and measuring shear. It is composed of equipment such as pallets. Main product index materials, aluminum and aluminum alloy. Thickness: 0.3-12mm (designed according to different thicknesses) Width: 600-1560mm Shear length: 500-4500mm Machine speed: 90m / min.
