Blast Furnace Ceramic Cup Series Shaped Products

Product Introduction

1. Plastic-Bonded Corundum Composite Brick Series  

This series is manufactured using corundum, mullite, high-quality silicon carbide, and metallic composite additives, formed through mechanical pressing and high-temperature firing. The novel plastic-phase composite corundum brick (TD-I) for large blast furnace ceramic cups achieves a porosity of only 11.0%, while maintaining thermal shock stability exceeding 25 cycles. This combination of low porosity and excellent thermal shock stability enhances the material’s resistance to erosion. The thermal conductivity at 1000°C is 6.22 W•(m•K)⁻¹, enabling the ceramic cup to effectively balance thermal insulation and protection of carbon bricks, thereby extending service life.

2. Composite Brown Corundum Brick

This brick is produced using high-quality brown corundum, silicon carbide, and additives, formed through mechanical pressing and high-temperature firing. It exhibits high strength, excellent resistance to slag erosion, and superior alkali resistance.

3. Corundum-Mullite Brick

This brick is made from premium corundum, mullite, and additives, formed through mechanical pressing and high-temperature firing. It is characterized by high strength and excellent resistance to iron erosion.
