Problems solved by technology

However, the existing high-copper and high-nickel aluminum alloy molten aluminum melting method is to add alloy element materials such as aluminum ingots, crystalline silicon, copper, and nickel in the melting furnace according to the proportion of materials for melting, which not only needs to increase melting equipment such as melting furnaces, but also It is necessary to set up a special melting process, which requires an increase in equipment investment and labor costs. There are problems of long smelting cycle and high smelting cost.

Embodiment Construction

[0026] The present invention will be further described below by embodiment.

[0027] (1) Determination of main element components of ZL109 aluminum alloy liquid:

[0028] ① Put the ZL109 aluminum alloy liquid for production smelted in the LX1500 gas-fired reflective melting furnace into the 500kg RBG-45-10 resistance holding furnace for pouring, and use the ALP-1000 metamorphic and refining integrated machine to fully stir evenly;

[0029] ② Use a pouring spoon to scoop up the aluminum liquid in the RBG-45-10 type resistance holding furnace, pour it into the sample mold for component detection, and pour the sample for spectral detection;

[0030] ③ After the sample is cooled, use a CL6132A ordinary lathe to process the excitation detection surface of the sample, which requires smooth turning, clear texture, flat, no oil and impurities;

[0031] ④ Use the DF100 direct-reading spectrometer to test the sample three times, one point each time, and take the average value of the th...

Abstract

The invention relates to the field of aluminum alloy casting, in particular to a smelting method for special high-copper and high-nickel liquid aluminum alloy for an internal combustion engine aluminum piston. The smelting method is characterized by comprising the following steps of (1) measuring major element compositions of ZL109 liquid aluminum alloy; (2) preparing the high-copper and high-nickel liquid aluminum alloy, calculating the addition quantities of copper and nickel and dissolving and fusing the copper and the nickel; and (3) measuring the content of the copper and the nickel in the high-copper and high-nickel liquid aluminum alloy. The smelting method has the beneficial effects that no additional smelting equipment is required, the smelting cost is saved, and the smelting cycle is shortened.

Description

technical field [0001] The invention relates to the field of aluminum alloy casting, in particular to a high-copper and high-nickel aluminum alloy liquid melting method specially used for aluminum pistons of internal combustion engines. Background technique [0002] There are many grades of cast aluminum piston materials for internal combustion engines, among which ZL109 is the most widely used. In the production process, some customers will customize the aluminum piston of supercharged internal combustion engine, and the material used is high-copper and high-nickel aluminum alloy. However, the existing high-copper and high-nickel aluminum alloy molten aluminum melting method is to add alloy element materials such as aluminum ingots, crystalline silicon, copper, and nickel in the melting furnace according to the proportion of materials for melting, which not only needs to increase melting equipment such as melting furnaces, but also It is necessary to set up a special smelt...
