Free-flowing Powders Calcium Silicon
Product Introduction
Free-flowing powders calcium silicon is a powder alloy material with good free-flowing properties made by a specific process with silicon (Si) and calcium (Ca) as the main components. The silicon content is usually 50%~60%, and the calcium content is 20%~30%. It may also contain a small amount of impurities such as iron and aluminum. It is mainly used as a deoxidizer, desulfurizer, and inoculant in steelmaking or cast iron to improve the purity of molten metal and improve the structure and performance of castings.
Product advantages
1. Strong deoxidation and desulfurization capabilities: Silicon and calcium have good affinity with oxygen and can effectively remove oxygen from molten steel or molten iron. At the same time, calcium can react with sulfur to form calcium sulfide, thereby reducing the sulfur content and improving the purity of the molten metal, which helps to produce high-quality steel and cast iron.
2. Improve the morphology of inclusions: It can make the oxide and sulfide inclusions in the molten steel larger and easier to float. At the same time, it can also change the shape and distribution of inclusions, and convert harmful long strips or flakes into spherical or granular inclusions, thereby improving the mechanical properties of the metal, such as improving the toughness, ductility and fatigue resistance of steel.
3. Good inoculation effect: In cast iron production, silicon calcium powder is an excellent inoculant, which helps to form fine or spherical graphite, make the graphite in gray cast iron evenly distributed, reduce the tendency of white cast iron, improve the strength and toughness of cast iron, and improve the quality and processing performance of cast iron.
4. Smooth reaction and easy operation: When calcium silicon powder is added to the molten metal, the reaction is relatively stable and will not produce violent reaction fluctuations, which is convenient for operators to control the process and is conducive to improving production efficiency and product quality stability.
5. Wide adaptability: The product varieties and specifications are diverse. Calcium silicon powder with different compositions and particle sizes can be customized according to different smelting processes and metal material requirements. It is suitable for a variety of steelmaking and cast iron processes, including converter steelmaking, electric furnace steelmaking, ductile iron production and other scenarios.
