AC6253 Sintered Corundum Refractory Brick

Sintered Corundum Refractory Brick Description

Sintered corundum refractories are high-performance refractory bricks primarily composed of corundum (Al₂O₃) as the main crystalline phase. This brick is recognised for its extreme hardness, high melting point, and excellent resistance to wear, corrosion, and high temperatures, and it is utilised in demanding applications that require long service life under harsh conditions. Sintered corundum bricks are produced by sintering high-purity aluminium oxide at temperatures typically exceeding 1,700°C to form a dense, stable structure.

Applications of Sintered Corundum Refractories

• Steel and Iron Furnaces: Used in areas exposed to high temperatures and corrosive slags, such as ladles, distributors, and blast furnaces.
• Glass Furnaces: Employed due to their heat resistance and minimal interaction with molten glass in high-temperature areas.
• Cement Kilns: Frequently used in critical areas of cement kilns where heat and wear resistance are essential.
• Petrochemical Furnaces: Utilised in linings for high-temperature reactors and furnaces in the petrochemical industry.

Frequently Asked Questions

Q1: What is a refractory sintered corundum brick?

A refractory sintered corundum brick is a type of high-temperature-resistant brick mainly composed of silicon dioxide (SiO₂), with a typical silicon dioxide content exceeding 93%. These bricks are well known for their excellent thermal stability and resistance to acidic environments, making them ideal for industrial high-temperature applications.

Q2: What are the main applications of sintered corundum bricks?

These bricks are commonly used in steel and iron furnaces, glass furnaces, cement kilns, and petrochemical reactors. They are ideal for areas requiring extreme heat resistance, corrosion resistance, and mechanical strength.

Q3: How do sintered corundum bricks differ from other refractory bricks?

These bricks are produced with a very high aluminium oxide content (often exceeding 90%) and offer superior hardness, low porosity, and excellent resistance to acidic and basic slags. They are more durable and provide better resistance to wear and corrosion compared to standard aluminium oxide or silicon dioxide bricks.
