Anchor-Free Refractory Solutions for Aluminium Melting & Holding Furnaces

Non-Wetting, Non-Penetrating Linings for Primary and Secondary Aluminium

Sharadaa offers a complete anchor-free refractory system for aluminium melting and holding furnaces — from non-wetting NANOBOND castables and phosphate bonded bricks for metal-contact hot face zones, to precast launder shapes, tap-out cones, and low thermal conductivity insulation backup products.

Every solution is engineered to resist aluminium penetration, handle thermal shock, and maximise furnace campaign life.
