1. Low fluorine content
An important feature of high manganese high silicon flux is its low fluorine content. Although fluorides have a good fluxing effect, they are highly corrosive to metal equipment. Fluorides react chemically with metal materials at high temperatures, causing corrosion and loss of equipment. Low fluorine flux reduces this corrosion effect, thereby extending the service life of the equipment.
2. The role of high manganese and high silicon
The role of manganese (Mn): Manganese is a good deoxidizer and desulfurizer that can effectively remove harmful impurities such as oxygen and sulfur in molten metal. Manganese can also improve the fluidity of the molten liquid, help reduce thermal and mechanical stresses during the melting and casting process, and thus reduce impact and wear on the equipment.
Function of silicon (Si): Silicon is a commonly used deoxidizer that can react with oxygen to form stable silicon dioxide, further reducing the oxygen content in the melt. Silicon can also increase the melting point of the flux, allowing it to maintain good stability at high temperatures and reduce corrosion and erosion to equipment.
3. Physical properties of the flux
Low melting point: High manganese and high silicon flux has a low melting point, which allows it to quickly mix with the molten metal during the casting process and cover the surface of the molten metal to form a layer of protective slag. This layer of slag can effectively isolate the molten metal from the air, reduce oxidation reactions, and also protect the equipment from direct erosion by the high-temperature molten metal.
High viscosity: High manganese and high silicon flux has a high viscosity, which allows it to better adhere to the surface of the molten metal to form a uniform slag layer. This not only helps to reduce the volatilization and splashing of the molten metal, but also reduces the erosion and wear of the molten metal on the equipment.
4. Chemical stability
High manganese and high silicon flux has good chemical stability at high temperatures and is not easy to react violently with other substances. This stability prevents the flux from producing violent chemical reactions when it comes into contact with the molten metal and equipment materials, thereby reducing corrosion and loss to the equipment.
5. Reduce thermal stress
High manganese high silicon flux can effectively adjust the temperature distribution of the molten metal and reduce thermal stress. Thermal stress is one of the main causes of cracks and damage to equipment. By using this flux, thermal stress can be effectively reduced and the durability of the equipment can be improved.
In summary, Melting Type High Manganese High Silicon Low Fluorine Flux can reduce the loss of equipment during the melting and casting process and extend the service life of the equipment through its low fluorine content, good deoxidation and desulfurization capabilities, stable chemical properties and physical properties.
