Synthetic Slag for Secondary Metallurgy and Steel Refining

Meta Description

Sintered and prefused calcium aluminate flux for ladle refining, desulfurization, deoxidation and inclusion removal. Fast slag formation, low power consumption and customized solutions for LF, EAF and secondary metallurgy.

Calcium Aluminate Flux for Steelmaking and Ladle Refining

Our Calcium Aluminate Flux is a high-performance synthetic slag designed for secondary metallurgy and ladle refining applications. Manufactured from carefully selected raw materials through sintering or prefusion technology, the product contains more than 85% calcium aluminate phases, primarily based on 12CaO·7Al₂O₃.

The flux promotes rapid slag formation, efficient desulfurization, deep deoxidation, and effective absorption of non-metallic inclusions. Its low melting point and excellent fluidity enable fast interaction between slag and molten steel, improving refining efficiency and steel cleanliness.

Widely used in LF Furnaces, Electric Arc Furnaces (EAF), Steel Ladles and Secondary Metallurgy Processes, the product helps steelmakers reduce refining time, lower power consumption, improve steel quality and extend refractory service life.

Available in both Sintered Calcium Aluminate Flux and Prefused Calcium Aluminate Flux grades, with customized chemistry and particle sizes according to customer requirements.

Why Choose Our Calcium Aluminate Flux

Key Benefits
