METALLURGICAL APPLICATIONS OF WOLLASTONITE
NATURAL FLUX FOR CLEANER METAL, THERMAL STABILITY & SLAG CONTROL
Used in steelmaking, non-ferrous metallurgy, and casting — wollastonite enhances metal quality and high-temp process stability.
InduMinerals supplies wollastonite grades for: – Steelmaking and continuous casting – Non-ferrous metallurgy (e.g., aluminum, copper) – Foundry applications as flux and slag conditioner Benefits include: – Desulfurization support – Inclusion absorption – Viscosity control in molten metal – Excellent thermal stability and low LOI – Chemically pure — no volatile impurities or off-gassing Ideal for use in high-temperature environments where process consistency and slag control are critical.
RECOMMENDED GRADES FOR METALLURGICAL USE
CUSTOM GRADES ON REQUEST

Available with tailored mesh size, bulk density, and blending ratios
-
Custom mineral blends possible for basic, acidic or neutral slag systems
APPLICATION AREAS
Use Case
Electric Arc Furnace (EAF)
Ladle refining
Gray & ductile iron
Tundish & casting powders
Non-ferrous metallurgy (Cu, Zn)
Function of Wollastonite
Slag conditioner / calcium source
Viscosity control, desulfurization
Cleaner melt, sulfur scavenging
Thermal insulation & slag trapping
Flux for oxide removal & flow control
KEY METALLURGICAL BENEFITS
Cleaner metal, reduced slag viscosity, natural flux performance.
– Acts as a low-lime flux in EAF and ladle metallurgy – Reduces slag viscosity for better metal separation – Promotes inclusion capture and cleaner steel – Enhances desulfurization in cast iron and steel – Used in continuous casting tundish linings & powders – Can replace synthetic slag additives with a natural alternative
