Main characteristics
Strong deoxidation ability: Both calcium and silicon can combine with oxygen to form stable oxides, which can significantly reduce the oxygen content in the molten steel when used for steelmaking.
Efficient desulfurization performance: Calcium combines with sulfur to form CaS, effectively reducing the sulfur content in molten steel.
Purification of molten steel: It can remove impurities, improve the purity of molten steel, and enhance the quality of steel.
High reactivity: The small particle size of the powder allows for faster and more uniform participation in smelting reactions.
Easy to press into balls or blocks: convenient for feeding according to the ratio, improving the utilization rate of furnace materials.
Application fields
1. Steelmaking industry
Deoxidizer and desulfurizer: Silicon calcium powder is widely used in converters, electric furnaces, and external refining processes (LF furnaces, VD furnaces, etc.), which can effectively remove oxygen and sulfur from molten steel, especially suitable for producing steel grades that require high purity and cleanliness.
Alloying materials: suitable for alloy adjustment of alloy structural steel, stainless steel, spring steel, gear steel, high-quality carbon steel, etc.
2. Foundry industry
Inoculant and Modifier: In the production of gray cast iron and ductile iron, silicon calcium powder can be used as an inoculant to refine the graphite structure, improve the mechanical properties and compactness of castings.
Improve fluidity: reduce slag inclusion and porosity during the casting process, and improve the overall quality of castings.
3. Refining outside the furnace (LF, RH, etc.)
Silicon calcium powder is used for deep deoxidation, controlling the morphology and quantity of inclusions in refining outside the furnace, and is a key material for producing clean steel.
4. Raw materials for pressing blocks
As an efficient composite deoxidizer, it can be mixed with other powders (such as aluminum powder, silicon powder, manganese powder, etc.) and pressed into alloy pellets for rapid addition and use in front of steel mills.
5. Welding materials
Silicon calcium powder can be used in electrode coating or flux to remove oxygen, impurities, and improve weld quality.
Market prospects of silicon calcium powder
With the continuous improvement of high-quality steel and high-purity metallurgical processes, silicon calcium powder has become an irreplaceable functional material in steel metallurgy. Especially for high-end steels such as high-strength steel, ultra-low sulfur steel, and stainless steel, the requirements for impurity control are becoming increasingly high, and the demand for silicon calcium powder continues to grow.
At the same time, with the development of green metallurgy, powder metallurgy, and intelligent feeding systems, it has also promoted the evolution of silicon calcium powder products towards high purity, customization, and spheroidization.
