Zhongkeda Refractories | High-Aluminum Bricks & Refractory Solutions for Industrial Applications

Our Refractory Products

AM & BM Mullite Clay Bricks

High-performance mullite clay bricks designed specifically for dry quenching furnaces. Excellent thermal shock resistance and structural stability at high temperatures.

AT & BT Mullite Carborundum Bricks

Advanced composite bricks combining mullite and silicon carbide for superior wear resistance and thermal conductivity in aggressive environments.

Dense Clay Bricks

High-density refractory bricks with excellent load-bearing capacity and resistance to slag penetration. Ideal for furnace linings and structural applications.

Low Creep High Alumina Bricks

Engineered for minimal deformation under prolonged high-temperature load. Contains over 75% Al₂O₃ for exceptional refractoriness and durability.

Lightweight Insulating Bricks

Thermal insulation refractories with high porosity and low bulk density. Reduces heat loss and improves energy efficiency in industrial furnaces.

Prefabricated Calcinator Face Blocks

Custom-shaped refractory blocks manufactured in a dedicated 2,000m² steel structure workshop for precise fit and optimal performance in calcinators.

Custom Shaped Refractories

We specialize in producing both standard and non-standard shaped refractory bricks tailored to client specifications and furnace geometries.

Unshaped Refractories

Unshaped Refractories (Monolithics)

Castables, gunning mixes, and ramming materials for seamless linings. Ideal for repair work and complex furnace zones where brick installation is difficult.

Industrial Applications

Our refractories are engineered for extreme thermal environments across key industrial sectors. From dry quenching furnaces to cement kilns, our materials ensure longevity, safety, and efficiency.

Dry Quenching Coke Ovens

Full refractory lining solutions including AM/BM and AT/BT series bricks for reliable performance under cyclic thermal stress and abrasive conditions.

Iron & Steel Industry

Refractories for blast furnaces, hot blast stoves, and ladles. High alumina and low creep bricks ensure structural integrity at extreme temperatures.

Coking Industry

Specialized bricks resistant to carbon deposition, thermal cycling, and mechanical wear in coke oven chambers and flues.

Carbon Industry

Refractory linings for calciners and anode baking furnaces. Designed to withstand high thermal gradients and chemical attack.

Glass Industry

High-purity alumina and silica-based refractories for glass melting tanks, regenerators, and checkers. Resistant to alkali vapors and molten glass.

Cement Industry

Refractories for rotary kilns, preheaters, and coolers. Optimized for abrasion resistance, alkali corrosion protection, and thermal shock stability.
