Embodiment 1
[0024] Embodiment 1 Preparation of aluminum-lithium alloy rod of the present invention
[0025] Batching smelting: prepare the materials according to: lithium 6wt%, copper: 6wt%, magnesium: 0.1wt%, tin 0.4wt%, zinc: 0.2wt%, manganese 0.05wt%, lanthanum and cerium: 0.2wt%, remaining The amount is the mass ratio of aluminum and put into the smelting furnace, the temperature of the smelting furnace is controlled at 750° C., and the time is 2 hours.
[0026] Detection: Spectroscopic analysis is used to detect the smelted alloy liquid to ensure that its composition is within the range.
[0027] Casting cold billet: adopt continuous casting method, use computer to control AC motor, realize micro-pitch reverse push process, produce large roll and heavy strip billet, mill the skin defects of strip billet through double-sided milling and milling unit, and pass through cold rolling mill , cut into rough round ingots with a diameter of 20-50mm and a length of 3-4 meters.
