Embodiment 1

[0033]Melt the aluminum alloy material with the following mass percentage composition at 750°C, add 0.01% detonating agent and 1.0% reinforcing agent of the aluminum alloy mass at the same time of melting, and stir it repeatedly with an iron rake for 25 minutes to completely melt it to obtain molten aluminum; The composition and mass percentage of the alloy material: Si: 6%, Fe: 0.1%, Mg: 0.5%, Zr: 0.01%, Ti: 0.01%, B: 0.03%, La: 0.02%, the balance is aluminum and not Avoided impurities; then the resulting aluminum liquid is refined, and the refining temperature is 780°C. After refining, cool to 690°C and preheat the mold to 150°C at the same time, pour the cooling liquid into the mold and cast to form the final product static plate.

Embodiment 2

[0035] Melt the aluminum alloy material with the following mass percentage composition at 753°C, add 0.011% detonating agent and 1.1% reinforcing agent of the aluminum alloy mass at the same time of melting, and stir repeatedly with an iron rake for 26 minutes to completely melt to obtain aluminum liquid; The composition and mass percentage of the alloy material: Si: 6.2%, Fe: 0.105%, Mg: 0.52%, Zr: 0.011%, Ti: 0.024%, B: 0.031%, La: 0.023%, the balance is aluminum and not Avoided impurities; then the resulting aluminum liquid is refined, and the refining temperature is 784°C. Cool to 692°C after refining, and preheat the mold to 158°C at the same time, pour the cooling liquid into the mold and cast to form the final product static plate.

Embodiment 3

[0037] The aluminum alloy material composed of the following mass percentages was melted at 756°C, and 0.012% detonating agent and 1.2% reinforcing agent were added to the mass of the aluminum alloy while melting, and stirred repeatedly with an iron rake for 27 minutes to completely melt to obtain molten aluminum; The composition and mass percentage of the alloy material: Si: 6.4%, Fe: 0.11%, Mg: 0.54%, Zr: 0.012%, Ti: 0.038%, B: 0.032%, La: 0.026%, the balance is aluminum and not Avoid impurities; then the resulting aluminum liquid is refined, and the refining temperature is 788°C. Cool to 694°C after refining, and preheat the mold to 166°C at the same time, pour the cooling liquid into the mold and cast to form the final product static plate.

Abstract

The invention relates to a stationary disc, in particular to a stationary disc for a scroll type compressor, and belongs to the technical field of alloy materials. The stationary disc is made of an aluminum alloy material, and the aluminum alloy material comprises, by mass, 6-8% of Si, 0.10-0.15% of Fe, 0.5-0.7% of Mg, 0.01-0.02% of Zr, 0.01-0.15% of Ti, 0.03-0.04% of B, 0.02-0.05% of La, and thebalance aluminum and unavoidable impurities. The aluminum alloy material used in the stationary disc is reasonably configured, and meanwhile, a specific preparation method is adopted, so that the obtained stationary disc has higher strength and higher corrosion resistance.

Description

technical field [0001] The invention relates to a static disc, in particular to a static disc for a scroll compressor, and belongs to the technical field of alloy materials. [0002] technical background [0003] Scroll compressor is an energy-saving compressor in today's world. It is also known as "ultra-quiet compressor" because of its stable operation, small vibration and quiet working environment. The scroll compressor has a novel and precise structure, small size, low noise, light weight, small vibration, low energy consumption, long life, continuous and stable gas transmission, reliable operation, clean gas source, etc., and is known as the "New Revolution". Compressor” and “No Service Compressor”. Scroll compressors are ideal power sources for pneumatic machinery, and are widely used in industries such as industry, agriculture, transportation, medical equipment, food decoration and prevention, and other occasions that require compressed air. [0004] The scroll compr...
