Refining agent can be widely used in metal smelting and casting industry, it is a variety of elements compounded, add more conducive to the smelting of metals. In the process of smelting metal deoxidation, desulfurization, phosphorus removal, gas removal are more difficult, now with the refining agent can effectively remove all kinds of impurities, so that the metal is more pure.
Adding refining agent is more conducive to metal smelting
If also in the process of smelting metal without timely removal of gas and impurities, there will be porosity, cracks, cold separation, shrinkage and other defects, resulting in a decline in product quality. After adding refining agent can eliminate the technical deficiencies encountered in the metal casting process, after adding can refine the grain, enhance the fluidity of the metal, and timely exclude impurities in the metal melt.
In addition, in the smelting process metal will be mixed with various oxides, sulfides, silicates, etc., after adding these impurities can be removed to improve the mechanical properties of the metal. In the smelting process, if the metal liquid is in contact with the atmosphere, there will be porosity-type defects, so the gas in the metal solution should be removed in time to improve its mechanical properties.
Adding can purify the metal melt, timely eliminating the exhaust gas in the melt, with obvious functions of deoxygenation, desulfurization and dephosphorization, thus reducing the content of impurities in the melt. The addition of refining agent can separate the residue, by mixing with the liquid to effectively exclude the exhaust gas and prevent pinholes, in addition to avoiding slag, ash, porosity, nodules, cold compartments and other defects.
Refining agent needs to be used in accordance with the conventional method, because the amount of refining agent is relatively small, so you can not expect the existing reduction and deoxidation are able to process. If there are crusts and slag on the surface during the smelting process, the surface floating slag should be removed in time before pouring.
