What is hot rolling technology in aluminum alloys?

Hot rolling technology in aluminum alloys refers to the rolling process of aluminum alloys above the recrystallization temperature of the metal.

1、 Characteristics of Hot Rolling

Significant reduction in energy consumption: During hot rolling, the metal has high plasticity and low deformation resistance, which allows the metal to withstand large amounts of deformation and requires relatively less energy consumption.

Improving processing performance: Hot rolling can break down coarse grains in the cast state, heal microcracks, reduce or eliminate casting defects, and transform the cast structure into a deformed structure, thereby improving the processing performance of the alloy.

Improving production efficiency: Hot rolling usually uses large ingots and large reduction rolling, with fast production pace and large output, which creates conditions for large-scale production.

Organizational and performance changes: The hot-rolled aluminum alloy plate and strip exhibit a microstructure state where recrystallization and deformation coexist. Due to the simultaneous hardening and softening processes during hot rolling, with the softening process playing a dominant role, the strength and plasticity indicators of hot-rolled products will vary within a certain range.

In summary, hot rolling technology in aluminum alloys is an important processing method with significant advantages such as reducing energy consumption, improving processing performance, and increasing production efficiency. By reasonable preparation before hot rolling, precise control of the hot rolling process, and wide selection of application fields, high-quality and high-performance aluminum alloy products can be produced.
