Alloy melting process

Melting temperature and time
The A356 alloy began to melt at about 580°C, completely melting at 640°C. The melting temperature is generally controlled below 760°C. When the temperature of the aluminum fluid exceeds 7700, the oxidation began to be obviously began, the contents of mixed objects and gas increased, the grains of the microcontrollers were thick after solidification, the quality of the aluminum liquid began to decrease, and the mechanical performance of the material deteriorated. It can be seen from Figure 1 that when the temperature of the aluminum fluid exceeds 770 ° C, the oxide mix has increased significantly, and the hydrogen content also increases, making the quality of aluminum deterioration worse. Therefore, the temperature should not exceed 770°C when the melting A356 alloy. A356 alloy liquid in lean furnace
The stay time should not exceed 3 hours. If you take a spectral sample for more than 3 hours, test whether all elements are within the scope of the ingredients: aluminum liquid is in.
The longest insulation time in the low-pressure mechanical insulation furnace is 4 hours. If more than 4 hours, spectral samples and density samples should be collected again to detect whether it meets the requirements. The unqualified aluminum liquid should be scooped out of the ingot.
