Machining technology of ultrawide 6061 aluminum alloy panel for military test detection platform

Abstract

The invention belongs to the technical field of aluminum alloy, and relates to a machining technology of an ultrawide 6061 aluminum alloy panel for a military test detection platform. Aluminum alloy is prepared from, by weight percentage, 0.63-0.69% of Si, 0.45-0.55% of Fe, 0.2-0.3% of Cu, 0.08-0.12% of Mn, 1.05-1.15% of Mg, 0-0.1% of Zn, 0.013-0.02% of Ti, 0-0.05% of Zr, 0-0.05% of single impurities, and the balance Al, wherein the total weight percentage of the above raw materials except Al is smaller than or equal to 0.15%. The lost pass is added in the hot rolling process, during shallow pass, by cooling the panel with rolling mill air-blowing equipment, the purpose of uniformly and slowly lowering the finish rolling temperature is achieved, arching of the back of the panel due to theexcessive width is avoided, and the problems that for the ultrawide 6061 aluminum alloy panel prepared through an existing machining technology, the contradiction between the width and flatness of thepanel and the machining deformation is prominent, and it is hard to meet customer needs are solved.

Description

Technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a process for processing ultra-wide 6061 aluminum alloy plates for military test and inspection platforms, and in particular to processing of ultra-wide 6061 aluminum alloy medium and thick plates for military test and inspection platforms with a thickness of 60-90 mm Craft. Background technique [0002] With the continuous development of modern industry, aluminum alloy is widely used in industry due to its high strength, good toughness, good heat resistance, excellent formability and damage resistance. Especially because of its good electrical conductivity, corrosion resistance, and weldability, it is often used as a test platform. For the military test and detection platform, the ultra-wide width of more than four meters is required to have high requirements for horizontal and vertical flatness, and sufficient internal stress release is required to achieve the pu...
