What Are the Characteristics of Sodium Free Refining Agent Used in Metal Smelting?


Various metal raw materials are used in many large factories and enterprises. Whether in the process of metal smelting or the pharmaceutical industry, we will see the use of many additives.

Among many aluminum manufacturers, sodium free refining flux are widely used. So, what are the characteristics of this sodium free refining flux?

1. What are the effects of adding sodium free refining flux in the smelting process?

In real life, we will see that the application of sodium free refining flux is more and more extensive, and the refining flux has many functions. It is used mainly to remove the hydrogen and floating oxidized slag inside the aluminum liquid, and then make the whole aluminum liquid more pure, after removing excess impurities.

Generally, degassing and slag removal are required in the process of smelting aluminum. You can add some refining flux when smelting. Sodium free refining flux is easy to decompose at high temperature, and its adsorption capacity is relatively strong. Sometimes it will escape from the melt to purify the melt. It needs to be used in the refining stage.

2. Adding sodium free refining flux is more conducive to metal smelting

Sodium free refining flux can be widely used in metal smelting and foundry industries. It is compounded by a variety of elements, and it is more conducive to metal smelting. In the process of metal smelting, deoxidation, desulfurization, dephosphorization, and degassing are all difficult. Nowadays, refining flux can effectively remove various impurities and make the metal more pure.

If the gas and impurities are not removed in time during the metal smelting process, defects such as pores, cracks, cold separation, and shrinkage will occur, which will result in a decline in product quality. The addition of sodium free refining flux can eliminate the technical shortcomings encountered in the metal casting process. After adding, it can refine the crystal grains, enhance the fluidity of the metal, and remove impurities in the molten metal in time.

In addition, in the metal smelting process, various oxides, sulfides, silicates, etc. will be mixed in. These impurities can be removed after being added sodium free refining flux to improve the mechanical properties of the metal. In the smelting process, if the molten metal is in contact with the atmosphere, there will be pore defects. Therefore, the gas in the molten metal must be removed in time to improve its mechanical properties.

The addition of sodium free refining flux can purify the metal melt, remove the exhaust gas in the melt in time, and has obvious functions of deoxidation, desulfurization and dephosphorization, and thereby reducing the content of impurities in the melt. The addition of sodium -free refining flux can separate the residue, and effectively remove the waste gas by mixing with the liquid to prevent pinholes. In addition, it can also avoid defects such as slag inclusion, ash inclusion, pores, nodules, and cold partitions.
