Manufacturing Process of Zirconium Corundum Bricks

The production of zirconium corundum bricks involves several key stages:

Raw Material Selection: High-purity zirconia and alumina raw materials are carefully chosen for their chemical stability and heat-resistant properties.

Batching and Mixing: The selected raw materials are precisely weighed and mixed to achieve a homogeneous blend.

Shaping: The mixed materials are shaped into bricks using molds or extrusion techniques, ensuring uniformity in size and shape. We also produce hard silica firebrick.

Drying and Firing: The formed bricks undergo controlled drying to remove moisture, followed by firing at high temperatures (typically above 1700°C) in kilns. This process promotes the formation of stable crystalline phases, enhancing the brick’s mechanical strength and thermal stability.

Quality Control and Testing: Rigorous quality checks are conducted throughout the manufacturing process to verify dimensional accuracy, density, thermal conductivity, and resistance to thermal shock.

Applications of Zirconium Corundum Bricks

Zirconium corundum bricks are integral to several industrial applications, including:

Steel Industry: Used in blast furnaces, ladles, and other high-temperature zones due to their excellent thermal shock resistance and erosion resistance.

Glass Industry: Utilized in glass tank furnaces and regenerators where harsh conditions require kiln refractory material with high refractoriness and chemical stability.

Petrochemical and Ceramics Industries: Applied in reactors, kilns, and incinerators due to their ability to withstand aggressive chemical environments and extreme temperatures.
