The steel industry is one of the world's most demanding environments for refractory materials. Blast furnaces, electric arc furnaces (EAF), basic oxygen furnaces (BOF), ladles, and tundishes all operate at extreme temperatures — typically between 1500°C and 1650°C — while enduring severe mechanical stress, thermal cycling, and aggressive chemical attack from iron oxides, slag, and molten steel.
Firebrics supplies refractory bricks and castables specifically engineered for each zone of the steel production chain. Our materials are tested to Chinese GB/T and international ISO standards, and our production is certified under ISO 9001:2015. From the hearth of a blast furnace to the lining of a ladle slide gate, every Firebrics product is designed to maximize campaign life and minimize unplanned downtime.
Key Application Zones
Hearth, tuyere zone, belly, and stack — requires high thermal conductivity at the hearth, alkali resistance in the stack, and extreme durability in tuyere surrounds.
Hot spots near electrodes and the bath zone experience extreme temperatures and arc radiation — magnesia-carbon bricks are the standard solution.
Steel transport vessels require rapid heat-up resistance, slag erosion resistance, and reliable performance during continuous casting sequences.
Trunnion zone, barrel, and bottom lining all demand high-strength magnesia-carbon bricks capable of withstanding intense mechanical and thermal shock.
