The methods procedures for manufacturing 5052 aluminum plate
The methods procedures for manufacturing 5052 aluminum plate : The process of turning aluminium and its alloy into sheet or coil with rectangular cross-section through smelting, ingot casting, various pre-rolling preparations, flat roll rolling, heat treatment and finishing. 1. Aluminum and aluminium alloy sheet strips are supplied in hot rolling, annealing, various grades of soft state and various heat treatment states. 2. Preparation before hot rolling mainly includes casting quality inspection, heat treatment, sawing, milling, aluminum cladding and heating. 3. In semi-continuous casting, the cooling rate is very high, the diffusion process in solid phase is difficult, and the chemical composition and structure of ingot are uneven, such as intragranular segregation, which reduces the plasticity. 4. When there are defects such as segregation, floatation, slag inclusion, scarring and crack on the surface of ingot, milling surface (see milling surface of non-ferrous me...
