The melting point of aluminum is 660.37℃. In practical applications, the post-melting treatment methods of aluminum will vary depending on the specific situation. The following are some common treatment methods:
Degassing and impurity removal:
The aluminum liquid may contain gas and impurities, which will affect the quality of aluminum. In the later stage of melting, the gas and impurities in the aluminum liquid can be removed by using flux, stirring, blowing and other methods.
Grain refinement:
Sometimes it is necessary to refine the grains of aluminum to improve its mechanical properties. This can be achieved by adding grain refiners or using specific solidification processes.
Alloying:
If aluminum alloys need to be prepared, other alloying elements can be added in the later stage of melting to achieve the desired composition and properties.
Temperature control:
Accurately controlling the temperature of aluminum liquid is very important for subsequent processing and use. In the later stage of melting, the temperature needs to be adjusted according to specific requirements to ensure the quality and performance of aluminum liquid.
Casting or molding:
According to the requirements of the final product, the molten aluminum liquid can be poured into a mold for molding, such as casting, die casting, extrusion, etc.
It should be noted that the melting and processing of aluminum needs to be carried out in professional equipment and environment, and follow relevant safety operating procedures. In addition, the specific processing method will also be affected by factors such as aluminum purity, alloy composition, and product requirements. Therefore, when performing the post-processing of aluminum melting, it is recommended to refer to relevant professional materials or consult professionals.
At the same time, you also need to pay attention to safety protection to avoid accidents such as burns.
