Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] A special aluminum alloy preparation process, its process steps are as follows,

[0013] Such as figure 1 As shown, first put pure aluminum ingots and intermediate aluminum alloy ingots into the furnace for smelting, when the melting temperature in the furnace reaches 650°C±10°C, add magnesium ingots and tin ingots and then smelt, when the melting temperature reaches 720°C±10°C ℃, use spectral analysis to analyze the smelted material, and then carry out refining treatment at a temperature of 740°C±10°C after the analysis is qualified. If the analysis is unqualified, adjust the smelting. The heat preservation electric furnace is used for heat preservation, and the temperature of the heat preservation electric furnace is controlled at 720°C ...

Abstract

The invention relates to an alloy material, and especially relates to a special aluminum alloy preparation technology. The technology is characterized in that the technology comprises the following steps: smelting pure aluminum ingots and master aluminum alloy ingots in a smelting furnace, adding magnesium and tin ingots when the smelting temperature in the smelting furnace reaches 640-660DEG C, smelting, analyzing the smelted materials through adopting spectral analysis when the smelting temperature reaches 710-730DEG C, refining at 730-750DEG C if the materials are qualified, carrying out adjusted smelting if the materials are not qualified, allowing the materials to stand for 10-20min after the refining completion, putting the materials in a heat-insulation electric furnace, carrying out heat insulation, and casting to form a blank. The special aluminum alloy prepared through the technology has the physical characteristics of high mechanical strength, high abrasion resistance, high fatigue resistance, high heat resistance, high gluing resistance, high saturability, high mosaicism to foreign matters, and the like, can effectively solve the seepage caused by the increased axial clearance because of the super-large shaft sleeve abrasion of a gear pump, can improve the service life and the output power of the gear pump, and makes the service life of the gear pump using the alloy be 1-3 times the service life of an original pump.

Description

technical field [0001] The invention relates to an alloy material, in particular to a preparation process of a special aluminum alloy. Background technique [0002] In recent years, with the upgrading of my country's hydraulic component industry, gear pumps have developed in the direction of high pressure, small volume, low noise, and long service life. At present, the wear resistance between the gear shaft and the shaft sleeve of the high-pressure gear pump in the world is large, and the service life of the high-pressure gear pump is also long. This has always been a major topic in mechanics and materials science, especially the representative gear pumps on the market now, because there is a big difference in the materials of the shaft sleeves that rub against each other between the gear end face of the pump body and the bearing seat, and 80% of them are damaged. It is all because of the shaft sleeve material that the entire pump is damaged. Seriously reduce the service l...
