Product Portfolio

Formed Refractory Products

Caihua manufactures a wide range of refractory bricks tailored for high-temperature kilns. These include high-alumina bricks, clay bricks (fireclay bricks), carbon bricks, magnesium bricks, silica bricks, and more. Each brick type exhibits excellent refractory properties, high-temperature strength, and thermal shock resistance. They are designed to withstand long-term high-temperature environments and maintain furnace structural integrity.

Custom Fireclay Bricks

Fireclay bricks are a specialty of the company. Using high-quality primary bauxite with a stable Al₂O₃ content of ≥75%, low impurities, and high density, combined with national standard grade refractory cement, these bricks offer superior performance. They feature a melting point ≥1750°C, high softening temperature under load, and compressive strength ranging from 60 to 120 MPa. Their thermal shock stability allows repeated rapid cooling and heating cycles exceeding 30 times without cracking or peeling.

Unshaped Refractory Materials

The castable series includes high-strength castables, wear-resistant castables, and insulation castables. These materials have excellent construction performance, high density after solidification, and strong erosion resistance. They are ideal for complex shapes and special areas. Refractory mortar series offer high bonding strength and good sintering performance, ensuring the sealing and integrity of brick masonry.

Ceramic Fiber Products

Caihua also produces lightweight refractory materials such as ceramic fiber blankets, boards, and cotton. These products have excellent heat insulation properties, low thermal conductivity, and good flexibility, effectively reducing heat loss and improving energy utilization efficiency.

Refractory Raw Materials

The company supplies high-quality raw materials like bauxite and high-alumina cement, providing reliable basic raw material guarantees for refractory production.
