Kerui offers various types of silicon carbide brick for various industrial uses, with rigorous quality management from raw material procurement through production process completion and inspection of final product.
Clay bonded silicon carbide brick is a refractory material composed of silicon carbide as its primary raw material, bound together by clay as the bonding agent. This brick offers high thermal conductivity, low coefficient of thermal expansion and excellent chemical resistance properties.
High-temperature resistance
Silicon carbide bricks are an industrial refractory product composed of silicon (Si) and carbon (C). Their main characteristics include high working temperatures, excellent thermal conductivity, low thermal expansion coefficient and resistance to chemical corrosion.
They are widely utilized in metallurgical steel electric arc furnaces, ladles and electric blast furnaces for steel production due to their ability to withstand extreme temperature conditions associated with these tools. Furthermore, their efficient use contributes greatly to efficient steel production.
These materials offer exceptional abrasion resistance and can withstand the extreme environmental conditions found in waste-to-energy plants and incinerators, including high temperatures, mechanical strain, chemical exposures such as acids or alkalis solutions, or molten metals.
Corrosion resistance
Silicon carbide bricks offer excellent chemical resistance and can withstand acids, alkalis, and molten metals without succumbing to corrosion or erosion. Furthermore, they’re durable enough to withstand abrasive materials and high velocity gas flows – making them the ideal material choice for use as equipment or pipe lining in harsh environments.
These bricks feature low thermal expansion coefficients and maintain their dimensions even at higher temperatures, making them suitable for precision lining applications in which precision is key, such as aluminum electrolytic cell linings or zinc distillation tanks in metallurgy industries.
Furnaces can use these bricks as liners and furniture pieces, specifically ceramic kilns. Furthermore, these bricks can also be utilized in non-ferrous metal smelting furnace retorts and slide linings of steel blast furnaces as well as for use in sintering, annealing, heating furnaces. Finally, this brick boasts an incredible Mohs hardness of 9 and has high impact resistance as well as wear resistance – perfect for incinerators use.
Wear resistance
Silicon carbide bricks offer outstanding resistance against wear caused by abrasion, erosion and impact – ideal for protecting equipment in harsh environments. In addition, their low thermal expansion rates allow them to tolerate higher temperatures without losing dimension stability.
Silicon Carbide Bricks are manufactured by using steel form work or wooden molds, then pressing with either a press machine or pouring by hand to form blocks or brick-shaped pieces that will later be fired in a reaction sintering furnace at 1350 to 1450 deg C in an atmosphere with less than 0.01% oxygen content (O2).
HarbisonWalker provides silicon carbide products designed for applications that involve frequent abrasion, such as aluminum electrolytic cell liners and zinc distillation tanks. Their protection includes alkali attack, melt cryolite formation, oxidation, thermal shock and corrosion, with superior strength in mechanically stressed areas.
Thermal shock resistance
Silicon carbide brick is highly durable, capable of withstanding high levels of wear and corrosion while providing outstanding thermal shock resistance – making it the ideal material to line equipment in industrial settings that experience both high temperatures and corrosion-causing chemicals. This makes silicon carbide ideal for protecting equipment linings in harsh industrial environments with rapid temperature changes or chemical attacks.
Refractory bricks are widely utilized in furnace and kiln applications. Their versatility allows them to withstand both high temperatures and mechanical stress, helping lower maintenance costs by prolonging equipment lifespan.
Silicon Carbide Refractory Bricks are ideal for lining ceramic kiln furniture and chemical equipment due to their exceptional alkali attack resistance. Industry standard alkali attack tests show minimal penetration and no bloating; thus ensuring these bricks will withstand aggressive environments for extended periods.
