Embodiment Construction

[0013] An aluminum alloy material for a triangular valve, which contains chemical element components and mass percentages: copper 0.7-0.9, silicon 2.2-22.5, manganese 1.8-2.1, magnesium 4.0-4.2, titanium 0.01-0.03, chromium 0.3-0.5 , molybdenum 0.005-0.008, the balance is aluminum.

[0014] The production method of described triangular valve aluminum alloy material is as follows:

[0015] (1) Prepare pure aluminum ingots and waste aluminum in a ratio of 1:0.5 as the source of aluminum matrix, put pure aluminum ingots into the furnace for melting, remove impurities, deoxidize, use refining agent for one-time refining, and add alloy components for alloying, Then add waste aluminum for melting, add refining agent for secondary refining, test and adjust the content of chemical elements to pass, casting, post-casting heat treatment, etc.;

[0016] (2) The order of batches of alloying elements put into the furnace during the alloying process is: (1) silicon, chromium, molybdenum; (...

Abstract

The invention relates to an aluminum alloy material for triangular valves, which contains the following chemical components in percentage by mass: 0.7-0.9% of copper, 2.2-22.5% of silicon, 1.8-2.1% of manganese, 4.0-4.2% of magnesium, 0.01-0.03% of titanium, 0.3-0.5% of chromium, 0.005-0.008% of molybdenum and the balance of aluminum. The aluminum alloy has the advantages of light weight, favorable wear resistance, low expansion coefficient, excellent corrosion resistance, favorable plasticity, low quenching sensitivity, long service time and lower cost than brass triangular valves, and is suitable for making triangular valves. Part of scrap iron is used as the raw material, and the raw materials are fed in batches, so that the alloy quality is more stable and uniform, thereby enhancing the comprehensive mechanical properties. When the refining agent is used for casting production, the porosity in the casting can be lowered by 1-2 degrees, the oxide inclusion content is Grade 2 or so, the air tightness of the casting is high, and the yield is high.
