Barium silicon FeBa18Si50
Barium Silicon alloy is one type of long lasting and high efficiency inoculant in cast ironproduction.
Barium silicon alloy is one type of ferroalloy with high activity, can be used asdeoxidizer and desulfurizer in steel making, always be used as inoculant in foundryindustry. Adding into steel making can reduce the happens of smoke and flame, andchange the nature and distribution of nometallic inclusion in steel can also improvethe cutting performance of mental. Used in foundry production can appear betterrecession-resistant capability and reduce the cutting section sensibility.
Physicochemical Properties
Chemical Composition
- The barium content is around 8% and the silicon content is approximately 60%, with the remainder mainly being iron and trace amounts of other elements. Generally, the aluminum content is no more than 3.0%, carbon no more than 0.2%, phosphorus no more than 0.04%, and sulfur no more than 0.04%.
Physical Properties
- Appearance: Usually presents as lumps or granules with a metallic luster, generally grayish to dark gray.
- Density: Somewhat higher than pure silicon, usually in the range of 3.0 - 3.5 g/cm³.
- Melting Point: Relatively high, typically around 1200 - 1300°C.
Production Process
- It is typically produced by smelting barium-containing ores, silica, and other raw materials in an electric furnace.
- Coke or other reducing agents are added, and reduction reactions occur at high temperatures to generate the alloy.
Applications
In Steelmaking
- Powerful Deoxidation: The silicon in the alloy can react with oxygen in the molten steel, effectively reducing the oxygen content and improving the steel's quality and purity.
- Effective Desulfurization: Barium has a strong affinity for sulfur. It can react with sulfur in the molten steel to form barium sulfide, which is easy to remove, thereby reducing the sulfur content and improving the steel's hot workability and toughness.
- Microstructure Modification: It helps to refine the grains of the steel, improve its strength, hardness, wear resistance and other mechanical properties.
In Casting
- Excellent Inoculation: In the production of gray iron castings, it can increase the number of graphite nuclei, refine the graphite structure, and improve the casting's strength and ductility.
- Good Spheroidizing: In the production of ductile iron, it promotes the spheroidization of graphite, making the graphite balls smaller and more spherical, and enhancing the casting's comprehensive mechanical properties.
- Improved Fluidity: It can improve the fluidity of the molten metal, which is beneficial to the filling of the mold in the casting process, reducing the occurrence of casting defects and improving the dimensional accuracy and surface quality of the castings.
In Other Fields
- Production of Special Alloys: It is used as an additive in the production of some special alloys to adjust the alloys' performance and meet specific requirements.
- Ceramics and Glass Industry: It may be used in the ceramics and glass industry to improve some properties of ceramics and glass, such as enhancing their strength and thermal stability.
