The refining agent can be widely used in metal smelting and foundry industries. It is a compound of multiple elements, and it is more conducive to metal smelting after adding. In the process of metal smelting, deoxidation, desulfurization, degassing, and degassing are all difficult. Nowadays, with the refining agent, various impurities can be effectively removed, making the metal more pure.
Adding refining agent is more conducive to metal smelting
If the gas and impurities are not removed in time during the metal smelting process, pores, cracks, cold barriers, shrinkage and other defects will appear, resulting in a decline in product quality. After adding the refining agent, the technical deficiencies encountered in the metal casting process can be eliminated. After the addition, the crystal grains can be refined, the fluidity of the metal can be enhanced, and the impurities of the molten metal can be eliminated in time.
In addition, various oxides, sulfides, silicates, etc. will be mixed in the metal during the smelting process. These impurities can be removed after being added to improve the mechanical properties of the metal. In the smelting process, if the molten metal is in contact with the atmosphere, pores will appear. Therefore, the gas in the molten metal must be removed in time to improve its mechanical properties.
The addition can purify the metal melt, remove the exhaust gas in the melt in time, and has obvious functions of deoxidation, desulfurization, and desulfurization, thereby reducing the content of impurities in the melt. The addition of refining agent can separate the residue, and eliminate the waste gas by mixing with the liquid to prevent the production of needles. In addition, it can also avoid slag inclusion, ash inclusion, pores, nodules, cold partitions, etc.
The refining agent needs to be used according to the conventional method, because the amount of the refining agent is relatively small, so it is not expected that the existing reduction and deoxidation processes can be used. If there are crusts or slag on the surface during the smelting process, the surface scum must be removed in time before pouring.
