Silicon Barium (Si-Ba) is an alloy of silicon (Si) and barium (Ba), widely used in the steel smelting and foundry industries. Silicon Barium usually contains 10% to 30% barium, with the rest being silicon and small amounts of other elements. It is an efficient compound deoxidizer and desulfurizer, especially suitable for the production of high quality steel and cast iron.
silicon barium features
1. Strong deoxidizing performance: the addition of barium makes the silicon barium alloy have stronger deoxidizing ability, which can effectively remove the oxygen impurities in the steel and improve the purity of steel.
2. Excellent desulfurization capacity: Silicon barium has strong desulfurization performance, which helps to remove sulfur in steel and prevent sulfur from embrittlement of steel.
3. Reduces inclusions: The deoxidation and desulfurization reaction produced by barium silicate in the steel liquid will reduce the non-metallic inclusions in the steel, and enhance the mechanical properties and processing performance of the steel.
4. Improve casting performance: the addition of barium can improve the fluidity and anti-shrinkage of the metal, reduce the porosity and cracks in the castings, and help improve the quality of the castings.
silicon barium uses
1. Steelmaking deoxidizer and desulfurizer: Silicon barium, as a compound deoxidizer in the steelmaking process, can effectively remove oxygen and sulfur impurities, which is especially suitable for the production of high-strength steel and special alloy steel to ensure the purity and mechanical properties of steel.
2. Industry of cast iron: In the production of cast iron, barium silicate not only improves the fluidity of castings, but also reduces defects in castings, such as porosity, cracks and shrinkage holes, and improves the overall quality of castings.
3. Improve the mechanical properties of steel: By adding barium silicate, the hardness, toughness and tensile strength of steel can be improved, which is suitable for the production of steel with high performance requirements.
4. Improve the efficiency of metallurgical reaction: The presence of barium can promote the deoxygenation reaction, reduce the oxygen content in the steel, improve the efficiency of metallurgical reaction and shorten the smelting time.
Silicon barium alloy is used in the steel smelting and foundry industry mainly to improve the quality of steel and cast iron, reduce impurities in the smelting process, and improve the performance of castings. Its strong deoxidation and desulfurization capabilities make it an indispensable additive in steel production.
