Product Introduction

Description

Al2O3-SiC-C Brick, referred to as ASC brick. It is made by adding graphite, bauxite, and additives, after batching, forming, drying and high temperature firing. ASC brick has very good high temperature performance and anti-oxidation, anti-flaking and anti-slag erosion properties, can withstand long-term high-temperature solution erosion, and has a long service life.

Al2O3-SiC-C bricks blend high-purity alumina (Al2O3), silicon carbide (SiC), and carbon (C) as the primary raw materials. Alumina ensures high refractoriness and chemical stability, while silicon carbide enhances thermal conductivity and abrasion resistance. Carbon content optimizes thermal shock resistance and corrosion resilience.

Al2O3-SiC-C Brick is mainly used as sliding nozzle slide, continuous casting tundish integral stopper, etc. It can also be used as lining for hot metal pretreatment and steel ladle lining. According to different manufacturing processes, aluminum carbon bricks can be divided into fired aluminum carbon bricks and unfired aluminum carbon bricks.

Fired aluminum-carbon bricks are ceramic bonding or ceramic-carbon composite bonding materials. They are widely used as sliding nozzle slides, long nozzles, immersion nozzle upper and lower nozzle bricks and integral stoppers for continuous casting. Unburned aluminum-carbon bricks are carbon-bonded materials. Because their oxidation resistance is significantly better than that of magnesia-carbon bricks and the corrosion resistance of Na2O slag is excellent, they have been widely used in hot metal pretreatment equipment.

Features

Exceptional Thermal Stability: Al2O3-SiC-C bricks exhibit superior thermal resistance, maintaining structural integrity at extreme temperatures, surpassing traditional refractories.
Enhanced Mechanical Strength: The combination of Al2O3, SiC, and C provides remarkable mechanical durability, reducing wear and ensuring longer service life in harsh environments.
Resistance to Thermal Shock: The presence of carbon contributes to superior thermal shock resistance, crucial for applications involving rapid temperature changes.
Excellent Corrosion and Erosion Resistance: These bricks withstand corrosive and erosive elements, making them ideal for aggressive industrial settings.
Low Porosity: The low porosity characteristic ensures minimal heat loss and excellent insulation properties.
