Tuyere Belt Products

Silicon Carbide and Alumina

Tuyere belts typically experience severe abrasion, high heat load, thermal shock and severe corrosion by molten iron, slag and intense alkali and zinc attacks.

Saint-Gobain Performance Ceramics & Refractories’ engineered tuyere surroundings can meet these challenges.

A unique range of refractory materials is available, including:

  • Si3N4 (Refrax® 20 SBF) and SiAlON (Sicanit® TB) preassembled bricks
  • Preformed no and low cement castables (Monoguard® and Monocoral®)
