In general, an aluminum alloy plate is manufactured through an aluminum alloy ingot, followed by heat treatment such as solution treatment, quenching treatment, and age hardening treatment. Through such heat treatment, aluminum alloy ingots have very low surface flatness due to process phenomena (burning), expansion, shape deformation, discoloration, and so on. Degrades.

In order to solve this problem, conventionally, a means for adjusting the heat treatment temperature or the temperature increase rate or preventing other deformation has been devised. However, it is almost impossible to effectively correct the deformation of the alloy ingot by a method such as the control of the temperature or the temperature increase rate, and it is very difficult to improve the deterioration of the surface quality due to discoloration or contaminant confinement. In order to improve surface quality and to improve the surface quality, the alloy plate is improved to flatten the surface by stretching or leveling the deformed alloy plate after heat treatment, to remove the impurities adsorbed on the surface of the alloy plate, to smooth the surface, and to produce a gloss effect.
