SK36 bricks are a type of firebrick or refractory brick that are commonly used in high-temperature industrial applications due to their excellent heat resistance.They are a specific type of high-alumina refractory bricks, known for their excellent performance in high-temperature industrial applications.SK36 Refractory Fire Bricks fall into the "high alumina" category, meaning their primary component is aluminum oxide (Al2O3). This high alumina content is what gives them their superior heat resistance.The Al2O3 content in SK36 bricks typically ranges from 48% to 60% or even higher (some sources indicate 55-60%). The presence of other oxides like SiO2 (silica) and Fe2O3 (iron oxide) is carefully controlled to ensure optimal performance.

sk36 high alumina brick can also be manufactured in various other standard and custom shapes to suit specific furnace designs.
Key Characteristics
High Temperature Resistance: Sk36 High Alumina Refractory Brick can withstand very high temperatures without melting or deforming.Suitable for extreme heat environments like blast furnaces, hot blast stoves, and glass kilns.
Chemical Erosion Resistance: Strong resistance to acidic and alkaline slag, making them durable in harsh chemical environments.
Thermal Stability: Low thermal expansion coefficient, reducing deformation at high temperatures.
Mechanical Strength: High compressive and flexural strength for structural integrity.
Low Thermal Conductivity: Provides good thermal insulation, minimizing heat loss.
Slag Resistance: Effective against slag corrosion, extending service life.
Thermal Shock Resistance: Good resistance to rapid temperature changes, preventing cracking.
