Abstract

The invention relates to a 2Al2 aluminum alloy casting process. Firstly, intermediate alloys including a copper-aluminum alloy, an aluminum-manganese alloy and an aluminum-titanium alloy are prepared and smelted; then pure aluminum is arranged in a crucible, the copper-aluminum alloy, the aluminum-manganese alloy and the aluminum-titanium alloy are added in batch and in sequence, and sufficient stirring while adding is carried out; magnesium metal is added into the crucible, and aluminum alloy liquid is prepared; the aluminum alloy liquid is subject to refining, slag removal and modification treatment; after sampling analysis is qualified, pouring is carried out, and crude workpieces are prepared; the crude workpieces are settled and corrected; and the crude workpieces are arranged in an aging oven to be subject to aging treatment, and a finished product is prepared through slinging treatment and machining. The 2Al2 aluminum alloy casting process has the beneficial effects that operation is convenient, the workpieces are molded through casting, raw materials can be saved, the production cost is reduced, the casting tissue density is good, the degree of finish is high, the workpiece quality is good, the size deformation is small, the finished product rate is high, and the production efficiency is high.

Description

technical field [0001] The invention relates to a 2A12 aluminum alloy casting process. Background technique [0002] 2A12 (that is, LY12 is equivalent to American Standard 2024) aluminum alloy is a high-strength duralumin. The traditional process is to use a power frequency induction furnace or a push-type resistance furnace to heat the 2A12 ingot to 480°C-495°C, and squeeze it through a hydraulic press to cool it. Extruded and heat-treated to produce qualified plates, bars, etc. Using this method to process various high-load parts and component materials wastes a lot of raw materials, and the production cost is too high, which is difficult for users to accept. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems existing in the prior art, and provides a 2A12 aluminum alloy casting process that can save raw materials and reduce production costs. [0004] Technical scheme of the present invention is: [0005] A kind of 2A12 ...
