How To Smelt Aluminum Pellets?

Aluminum pellet smelting is to heat the aluminum pellets to their melting point first, and then smelt them through smelting equipment. Here are the detailed steps:

1. Preparation: First, you need to prepare the smelting equipment, including smelting furnace, fuel, solvent, etc. At the same time, ensure that the operating area is well ventilated to prevent the release of harmful gases when the aluminum pellets burn.

2. Heating aluminum pellets: Put the aluminum pellets into the smelting furnace and gradually heat them to the melting point of aluminum 660.32℃. Natural gas, liquefied gas, etc. can be used as fuel for heating, or electric heating can be used.

3. Adding solvent: During the melting of aluminum pellets, some solvents can be added in appropriate amounts to help remove impurities. Commonly used solvents include hydrochloric acid, sodium hydroxide, etc.

4. Stirring and filtering: During the smelting process, use a stirrer to continuously stir the aluminum liquid so that the solvent can completely dissolve the impurities. Then remove the remaining impurities by filtering and other methods.

5. Refining treatment: For aluminum materials with special requirements, refining treatment can also be carried out, such as vacuum treatment, argon protection, etc., to ensure the purity and quality of aluminum.

6. Casting: Finally, the molten aluminum is cast into shape. It can be poured into the mold for casting as needed, or it can be processed in other ways.
