Silicon Calcium Powder is a calcium–silicon alloy in powder form, mainly used as a composite deoxidizer and desulfurizer in steelmaking and foundry processes. It improves molten metal cleanliness, enhances mechanical properties, and supports efficient refining in carbon steel, alloy steel, and special metals.
features
High Calcium Reactivity
Ensures rapid chemical interaction with oxygen and sulfur in molten metal, improving refining efficiency and reducing treatment time.
Strong Deoxidation Capability
Combines the deoxidizing strengths of silicon and calcium, enabling deeper and more stable oxygen removal than single-element alloys.
Good Metallurgical Compatibility
Suitable for use in various steelmaking processes (converter, electric furnace, ladle refining) with stable reaction behavior.
Flexible Particle Size
Available in powder or granular form, supporting wire injection or direct addition for different process requirements.
applications
Steelmaking
Used as a deoxidizer and desulfurizer; can partially replace aluminum in final deoxidation.
Cast Iron Production
Functions as an inoculant additive, improving microstructure and mechanical properties.
Wire Injection Processing
Fine powder is commonly used as cored wire filling to achieve controlled and efficient metallurgical reactions.
