Oxidation-bonded silicon carbide brick is an advanced refractory material primarily used for lining non-ferrous metal smelting facilities and alumina industries, being resistant to high temperatures, chemical corrosion and mechanical stress.
Acknowledging the differences between corundum and silica bricks is essential to selecting an effective refractory material for industrial needs. This article offers a comparison guide that can assist in making an informed decision.
High-Temperature Resistant
Silicon carbide brick is an economical building material with versatile applications. Highly durable and corrosion-resistant, it makes an excellent choice for high temperature environments while its thermal properties help optimize operations while decreasing energy consumption.
Silicon carbide refractory brick production entails multiple steps, beginning with selecting high-grade raw materials. Manufacturers then mix these selected ingredients, shape them into green bricks and dry them before pre-firing and high temperature firing in special kilns or furnaces.
Clay-bonded silicon carbide brick is an extremely popular type of silicon refractory brick used extensively throughout metallurgical industries as an aluminum melting furnace lining, rectification furnace tray lining material, aluminum electrolysis tank lining material, copper melting furnace lining material and zinc powder furnace arc plate material – among others. This brick has become indispensable to manufacturing operations because of its superior thermal performance properties and widespread usage across industries and applications ranging from aluminum melting furnace linings, to rectification furnace tray linings, to zinc powder furnace arc plate thermocouple protection tubes among other uses.
Extremely Durable
Silicon carbide bricks are an innovative refractory material being utilized by industry to meet high temperature industrial needs. This revolutionary material can be found lining kilns and furnaces as well as blast furnace reheating areas due to its exceptional strength and resistance against extreme temperatures and corrosive environments.
Clay-bonded silicon carbide bricks have low bulk density. Production of these bricks is simple and efficient: an SiC body containing black silicon carbide is mixed with soft clay and pulp waste liquid to reach a stable consistency for production. As a result, these products possess exceptional alkali corrosion resistance, resistance against molten iron/slag corrosion as well as thermal stability at elevated temperatures.
Oxidation-bonded silicon carbide bricks are ideal for lining non-ferrous metal smelting furnaces, rotary kilns, crucibles and incinerators with non-ferrous metals smelting furnaces, rotary kilns, crucibles and incinerators. Highly durable yet chemical resistant against aggressive chemicals used during metal processing; thermal conductivity that stands up well and thermal shock withstanding properties make these bricks an excellent solution.
Extremely Resistant to Corrosion
Silicon carbide’s physical properties make it an excellent material for applications requiring superior strength and precision, such as its low coefficient of thermal expansion compared to steel; moreover, its resistance to corrosion and abrasion makes it more suitable than other refractory materials.
SIC brick boasts exceptional resistance to slag corrosion in ferrosilicon electric furnaces due to its unique, slag-free pore structure that facilitates easy water absorption while creating an effective barrier.
SIC brick is known to withstand high thermal shock cycles without breaking down, making it ideal for applications that involve aluminum reduction electrolytic cell lining, ceramic kiln furniture, and other high-temperature applications. Furthermore, its production does not release harmful pollutants during production – contributing to more sustainable and efficient construction industry practices in general.
Extremely Resistant to Wear
Silicon carbide is the third hardest material on Earth, behind only diamond and boron carbide. This extraordinary hardness contributes to its superior wear resistance – which protects it from mechanical stress or impact damage – as well as being highly chemical resistant, making it an attractive material choice for applications requiring high thermal stability or specific electrical characteristics.
Oxidation-bonded silicon carbide brick is an advanced refractory material created through an oxidation process which bonds black silica to high-purity fused mullite, producing bricks suitable for high temperature industrial applications such as kilns, furnaces and incinerators. They offer excellent resistance against thermal shock and chemical corrosion making them suitable for aluminum smelting processes.
Silicone Carbide Brick provides businesses with many unique benefits that can save them money and improve efficiency, including money saved on construction costs and improved efficiency. Refractory materials such as this one make an invaluable addition to any company’s construction arsenal.
