Calcium Silicon Alloy Supplier For Steelmaking

Calcium Silicon is a composite alloy composed primarily of calcium, silicon, iron, and other trace elements. It serves as an essential additive in steelmaking and casting processes, offering excellent deoxidation, desulfurization, and inclusion modification capabilities.

Ca content: 28% – 32%

Si content: 55% – 65%

Fe content: Balance

Al content: ≤ 2.0%

C content: ≤ 1.0%

Particle size: 10 – 50 mm, 10 – 100 mm, or customized

Appearance: Silver-gray metallic lump

Deoxidation – Effectively removes oxygen from molten steel, improving steel cleanliness.

Desulfurization – Reduces sulfur content, enhancing steel quality and performance.

Inclusion Modification – Transforms harmful inclusions into harmless spherical ones, improving machinability and mechanical properties.

Alloying – Provides calcium and silicon elements to adjust steel composition.
