Our products

A complete range for molten-metal operations

From insulation and covering to slag treatment, casting and nozzle products — engineered for every stage of melting, transfer and casting.

Insulation Ball Innsulekx rice husk ash insulating balls

Ball Innsulekx

Rice-husk-ash insulating balls that form a low-density insulating layer on the bath to lock heat in — easy to apply and remove in the ladle and tundish.

LadleTundishHeat retention
Active Tundish Cover Slagex AGI active tundish covering compound sample

Slagex AGI

Active covering compound that insulates the tundish bath, absorbs inclusions and prevents reoxidation for cleaner cast steel.

CastingInclusion control
Slagex Slagex slag coagulant sample

Slagex

Coagulates furnace and ladle slag into a dry, cohesive mass for fast, safe skimming and improved metal yield.

Slag removalYield
Slagex Ph3040 Slagex Ph3040 de-phosphoriser sample

De-Phosphoriser (Ph3040)

Reduces phosphorus in the melt so producers can hit tighter chemistry targets for quality-critical steel.
