Embodiment Construction

[0022] The processing technology of anti-fatigue aluminum alloy foam mold casting comprises the following steps:

[0023] (1) Ingredients

[0024] According to the mass percentage of elements, the following requirements are met: Si≤0.5%, Fe≤0.5%, Cu 3.6-4.5%, Mn 0.40-0.8%, Mg 1.2-1.6%, Cr≤0.1%, Zn≤0.25%, Ti≤0.15% , La 0.04-0.06%, Ce 0.05-0.08%, Y 0.03-0.04%, the total of other impurity elements ≤0.15%, the rest is Al, for batching;

[0025] (2) Melting

[0026] Put the ingredients into the smelting furnace in turn for smelting. The furnace is controlled at 735°C. After feeding for 50 minutes, when aluminum water appears in the furnace, add a covering agent to cover and start stirring. After adjusting the composition, add a refining agent for refining and slag removal After obtaining the qualified components, pour the molten aluminum from the melting furnace into the holding furnace, keep the furnace temperature at 720°C for 30 minutes, and then use argon to bring...

Abstract

The invention discloses a processing method of an anti-fatigue aluminum alloy foaming die cast. The processing method comprises the four steps of compounding, smelting, pouring, and thermal treatment. According to the invention, an appropriate amount of rare earth elements La, Ce and Y are added to the aluminum alloy, so that the hydrogen content in the alloy and the alloy yielding anisotropy can be reduced, the alloy plasticity and the anti-fatigue property of the alloy are obviously increased, and at the same time the wear resistance, thermal resistance and high-temperature strength of the alloy can also be improved. The processed aluminum alloy refrigerator foaming die cast has the advantages of good mechanical properties, high strength, good thermal resistance, good usability, good internal structure compactness, no pore and peeling defects, good wear resistance, good corrosion resistance and oxidation resistance, small expansion coefficient and the like.

Description

technical field [0001] The invention relates to a processing technology of an anti-fatigue aluminum alloy foam mold casting, belonging to the technical field of aluminum alloy material processing. Background technique [0002] Refrigerator foam mold is an important mold for the manufacture of refrigerators. The quality of its processing and manufacturing will directly affect the quality of the entire product, and even affect the success or failure of the entire product manufacturing. At present, there are two types of materials that can be used as refrigerator foam molds: metal and non-metal. The foam mold made of metal can undoubtedly be used in large-scale and high-speed production. The metal materials of the foam mold include aluminum, copper, low melting point alloy, Nickel, iron, zinc alloy, etc. Among them, the foam mold made of aluminum alloy is the most widely used. It has the advantages of good thermal conductivity, easy to adjust the mold temperature, not easy to...
