Refractory Sand
Maximum opening for fast easy flow!
For fully efficient EBT tap holes fillers, OLIMAG brings its MAGFILL® line of refractory sands.
With perfectly balanced sizing, MAGFILL® sands ensure a maximum tap opening for fast free flowing of melted steel every time.
OLIMAG high temperature calcination process allows complet elimination of impurities so to generate a chemically homogeneous sand with optimal refractory properties. The MAGFILL® sand forms a fully sealed efficient refractory plug on the spout surface, with minimum sub-surface sintering below the fused layer, for greater tapping efficiency and improved productivity.
MAGFILL® basic pH chemistry prevents damaging reaction with basic magnesite and magnesia carbon tap holes refractories, so to ensure longer equipment life cycle and longer melting campaigns.
MAGFILL® efficiency is highly appreciated in more than forty steel mills in Canada, USA, Mexico, Venezuela, Chile, Argentina, Trinidad and Spain.


In order to meet the most demanding requirements, MAGFILL® sands are proposed in a complete line of sizings:
