Features

Features

Enhanced Strength at High Temperatures

With refractoriness under load (RUL) ≥1520°C, our dense refractory firebricks maintain structural integrity under both intense heat and heavy mechanical load, making them suitable for boiler walls, combustion chambers, and kiln arches.

Resists Alkali, Slag, and Gas Infiltration

Laurel dense firebrick refractory is designed to resist degradation from alkali vapors, slags, and fuel combustion byproducts—critical for applications in incineration plants and metallurgy.

Ideal for Thermal Cycling

These dense refractory firebricks are engineered with a crack-resistant matrix, allowing them to handle repeated heating and cooling without structural failure.
