The thick china aluminum plate can be divided into ingot hot rolled thick plate and cast thick plate from the production process. Wherein the thickness of the cast Thick Aluminum Plate Sheet can be basically unlimited (maximum thickness reaches 1.2 m), but the hot rolled thick plate has better mechanical properties after the rolled process, so the aerospace products generally use ingot hot rolled thick plates. However, the thickness of the hot-rolled aluminum plate cannot exceed 250 mm, otherwise the cast structure cannot be completely turned into hot-rolled structure. The typical production process of ingot hot rolled thick aluminum plate is: raw material – casting – ingot milling – hot rolling – solution treatment – quenching – stretching – sawing. Since the temperature difference between the inside and outside of the plate during quenching is too large, when the thickness of the aluminum plate exceeds 6 mm, a large quenching residual stress ...
