Silicon Barium Calcium

Silicon Barium Calcium is a composite ferroalloy containing Si, Ba, and Ca.It is used as a deoxidizer, desulfurizer, and inoculant to improve steel and cast iron quality. The alloy refines microstructure, reduces gas content, and stabilizes mechanical properties.

Strong Deoxidation

Si, Ba, and Ca reduce residual oxygen in molten steel by forming stable oxides, improving steel purity and process reliability.

 

Effective Desulfurization

Ba and Ca react with sulfur to form low-melting-point sulfides, lowering hot brittleness and reducing inclusions.

 

Nitrogen & Hydrogen Control

Limits nitrogen and hydrogen absorption, preventing pinholes and microcracks in steel and castings.

 

Grain Refinement

Promotes fine, uniform microstructure in steel and cast iron, ensuring consistent strength and toughness.

 

Casting Flow Improvement

Optimized particle size enhances molten steel fluidity, reducing nozzle clogging and improving casting quality.

 

 

Composition: Si, Ba, and Ca ratios adjustable for specific steel grades or casting applications.

 

Particle Size: Options for furnace addition or inoculation.

 

 

Steelmaking：Acts as a composite deoxidizer and desulfurizer for high-quality steel, including spring steel, bearing steel, and specialty alloys.

 

Casting Industry：Functions as an inoculant to refine iron structure and reduce casting defects.

 

Alloy Production：Added in special ferroalloy manufacturing to optimize composition and metallurgical performance.
