Product Range: Shaped and Unshaped Refractories

Formed Refractory Products

The company produces a wide variety of refractory bricks tailored to specific kiln applications. Materials include high-alumina bricks (with Al₂O₃ content often ≥75%), clay bricks, carbon bricks, magnesium bricks, silica bricks, and more. These bricks exhibit excellent refractory properties, high-temperature strength, and thermal shock resistance, ensuring the integrity of furnace structures under long-term high-temperature environments. For instance, the high-alumina wear-resistant brick series is ideal for cement kiln transition zones, while the carbon bricks are perfect for blast furnace hearths.

Unshaped Refractory Materials

Zhengzhou Caihua offers a comprehensive line of unshaped refractories, including castables, ramming mixes, and refractory mortars. The castable series includes high-strength castables, wear-resistant castables, and insulation castables, which have excellent construction performance, dense solidification, and strong erosion resistance. Refractory mortars are available for various bricks, ensuring high bonding strength and good sintering performance to maintain sealing and integrity of masonry.

Ceramic Fiber Products

The company also manufactures lightweight ceramic fiber products such as blankets, boards, and cotton. These provide exceptional heat insulation, low thermal conductivity, and flexibility, effectively reducing heat loss and improving energy utilization efficiency.

Refractory Raw Materials

As a one-stop supplier, Zhengzhou Caihua provides high-quality bauxite and high-alumina cement as raw materials, with high purity and stable performance, offering reliable foundational materials for other refractory producers or internal use.
