Industry · Aluminium & Non-Ferrous

For aluminium, zinc and copper plants

Non-ferrous metallurgy is unforgiving on refractories: aluminium attacks alumina-based brick by reduction, dross builds up everywhere, and any iron pickup ruins the metal. We supply the low-iron, non-wetting linings that aluminium plants actually want — silicon-carbide for cells, low-cement bauxite castables for melting furnaces, and engineered shapes for launders and tap-out blocks.

Supply & Despatch

Aluminium-belt customers in Pune, Belagavi, Hirakud and Renukoot draw from our Chakan stock, with engineered specials (launder shells, tap-out blocks) made-to-drawing in our PCPF facility. We coordinate dispatch with cell-line shutdown windows.

Aluminium & Non-Ferrous questions, answered

Quick answers to the questions plant maintenance teams ask us most often.

Do your castables contain non-wetting additives for aluminium?
Yes. The aluminium-furnace-grade castables we supply are formulated with non-wetting additives (typically BaSO4 + SiC at controlled levels) to suppress corundum growth and dross adhesion at the metal-line.

Can you guarantee low iron for the casting-furnace bricks?
Yes. Low-iron grade selection is critical for aluminium — Fe2O3 typically <1.5% in the working face. Test certificates ship with each lot.

Do you supply launders and tap-out blocks pre-cast?
Yes. Launder shells, tap-out blocks, peripheral cell seals — all available as PCPF (pre-cast pre-fired) shapes, made to your drawing. This eliminates on-site dry-out and reduces shutdown time.

Are your SiC cell sidewall bricks oxidation-tested?
Yes. Nitride-bonded SiC for cell sidewalls is supplied with oxidation-resistance test data — weight gain after 24 h at 1200 °C in air is typically reported.
