Case Study Steel – Blast Furnace Linings

Durable Refractory Linings for Blast Furnaces in the Steel Industry

Vulcan Refractories supplies high-performance refractory solutions for blast furnace linings, engineered to withstand the extreme thermal, chemical, and mechanical stresses encountered in modern steelmaking. Our materials are specifically designed for use in the shaft, bosh, and tuyere zones, providing long-lasting protection and optimal furnace performance.

Applications in Blast Furnace Linings

Vulcan’s refractory products are used in key areas of the blast furnace, including:

  • Shaft zone: where thermal conductivity and erosion resistance are essential
  • Bosh zone: exposed to high temperatures and alkali attack
  • Tuyere zones: requiring strong resistance to oxidation and mechanical wear

These linings are critical in maintaining efficient furnace operation, reducing downtime, and ensuring long-term structural integrity.

Key Performance Characteristics

Our premium linings deliver exceptional performance in the most demanding furnace conditions:

  • High thermal conductivity – Promotes efficient heat transfer and temperature stability
  • Erosion resistance – Especially effective in the upper shaft, reducing wear from raw materials
  • Alkali and temperature resistance – Ideal for the lower shaft and bosh areas
  • Oxidation resistance – Ensures longevity in tuyere zones, where oxygen exposure is high

These properties support longer service life, reduced maintenance, and more consistent blast furnace operation.

Silicon-Nitride Bonded Silicon-Carbide Bricks & Shapes

Vulcan manufactures premium-quality bricks and pre-formed shapes using silicon-nitride bonded silicon-carbide, a material known for:

  • Exceptional wear and corrosion resistance
  • Stability at high temperatures
  • Resistance to alkalis, slag, and gas infiltration

Customised shapes are available to suit the unique dimensions and requirements of each blast furnace installation.

Our solutions are trusted by leading steel producers for efficiency, durability, and reliability in blast furnace environments.
