Thermal Processing Of Aluminum Processing

Thermal processing refers to the plastic forming process performed on aluminum and aluminum alloy ingots above the recrystallization temperature. In hot working, the ingot has higher plasticity and lower deformation resistance, and it is possible to produce a product with a large deformation amount with a device having a small capacity. In order to ensure the structural properties of the product, the heating temperature, deformation temperature and deformation speed of the workpiece, the degree of deformation, and the temperature at the end of deformation and the cooling rate after deformation should be strictly controlled. Common aluminum alloy thermal processing methods include hot extrusion, hot rolling, hot forging, hot forging, liquid die forging, semi-solid forming, continuous casting and rolling, continuous casting and rolling, continuous casting and continuous extrusion.
