What are the advantages of hot rolled aluminum plate?
Hot rolled aluminum plate can significantly reduce the energy consumption and reduce costs.When hot rolled aluminum metal plasticity, low deformation resistance, greatly reduce the energy consumption of metal deformation.
Hot rolled aluminum plate can improve the processing performance of aluminum metal and alloy, the casting of the state for the bulky grain breakage, crack healing, significantly reduce or eliminate the casting defects, the as-cast into deformation, improve the processing performance of aluminum alloy.
Hot rolling usually adopts large ingot which not only improves the production efficiency, but also creates the conditions for increasing the rolling speed and realizing the continuity and automation of the rolling process.
Hot rolled aluminum plate can not control the mechanical properties required by the product very precisely,the microstructure and properties of the hot-rolled aluminum product can not be uniform. Its strength index is lower than cold work hardening products, but higher than completely annealed products; plasticity index is higher than cold work hardening products, but lower than completely annealed products.
The thickness of hot-rolled aluminum products is difficult to control the thickness of the control accuracy is relatively poor; hot-rolled aluminum products on the surface of the rough rolling Ra value is generally 0.5 ~ 1.5μm. Therefore, the hot-rolled aluminum products are generally more as cold-rolled blanks.
