Silicon carbide refractory is an important raw material in industrial furnaces due to its resistance against oxidation, thermal shock and abrasion. With such properties in mind, silicon carbide refractory has found wide application.
Sic refractory materials consist of quartz sand, petroleum coke and coal coke that is produced through high temperature smelting in a resistance furnace. Its production is both cost effective and resistant to slag formation.
Hög hållfasthet
Sic refractory’s high strength makes it ideal for use in power generation industries, consisting of fine silicon carbide particles embedded within a ceramic matrix and offering long thermal cycles with good oxidation resistance properties.
Rongsheng offers silicon carbide refractory brick, castable refractory material and ramming mass for various applications. Our silicon carbide materials can be found in electric arc furnace bottom lining, power frequency melting trench lining and tundish working lining applications and can withstand up to 1500 heat cycles under appropriate maintenance.
Refractory castable is composed of refractory aggregate, silicon carbide powder and binders and doesn’t require any calcination for formation. As an unshaped material it can be constructed via manual or machine ramming before hardening at temperatures above normal temperature for hardening. Silicon carbide refractory castable is commonly found in industrial furnaces like these:

Motståndskraft mot höga temperaturer
Refractories used in high temperature environments typically need to combine strong strength with high thermal shock resistance – something silicon carbide refractories excel at providing. They have multiple uses such as metal smelting furnace linings, ceramic, enamel, and cement rotary kiln mouth linings, blast furnace linings, glass tanks for storage tanks as well as structural ceramics and domestic ceramics.
SiC’s exceptional high-temperature properties make it the ideal material to use in extreme conditions, including impact resistance and abrasion resistance, making it extremely durable material. In addition, its chemical stability in both oxidative environments as well as acid-base environments makes SiC a safe option.
Thermal conductivity of ceramic is very high, making it an efficient heat transfer material in high temperature environments. Furthermore, its coefficient of thermal expansion is relatively low so its dimensions do not change much when exposed to heat.
Refractory material offers excellent corrosion resistance and wear resistance, in addition to being chemically inert; making it particularly suitable for use in highly corrosive chemical and petrochemical equipment.
Silicon Carbide (SiC) refractory bricks and castables are known for being extremely durable, offering protection from abrasion, impact, wear, corrosion and more. Castables made from SiC are available in different shapes, sizes and compositions; castings have also been developed to be suitable for various high temperature applications – for instance Refrax ARC silicon nitride bonded refractories are commonly found in charging areas of glass furnaces to withstand impact from charge carriers agitation while withstanding impacts from high impacts or wear caused by charge carriers agitation.
Motståndskraft mot korrosion
Silicon carbide refractory bricks offer great corrosion resistance against many chemicals, making them an excellent choice for hard smelting of nonferrous metals such as aluminum. Their wide application includes aluminum electrolysis tanks, rectification furnace trays, copper melting furnace lining and zinc powder furnace arc plates; additionally they’re often chosen as the material of choice in large blast furnace linings due to their low thermal expansion rate and excellent chemical stability.
Refractory materials made of black silicon carbide are widely utilized in the iron and steel industries. Their excellent resistance to slag erosion allows them to maintain Vickers hardness even at higher temperatures, providing protection from high-temperature molten iron flowing through steel melting furnaces while withstanding any impact from heavy equipment.
Refractory materials made of black sic have an ideal combination of thermal conductivity, low expansion rate, resistance to thermal shock and chemical attack as well as being capable of withstanding erosion from slag and flame erosion in iron and steel furnaces. As a result, they’re extremely useful in the production of metals such as steel and cast iron while simultaneously serving other industries with products like abrasives, ceramics and high-purity graphite production – making this material suitable for automotive brake discs, pistons and diesel particulate filters among many others as well as being essential raw material in glass manufacturing and semiconductor industries.
Abrasion Resistance
Sic refractory has the ability to withstand impact and abrasion, making it ideal for use in areas that experience high levels of mechanical wear and tear, such as charging blocks. Due to its low thermal expansion rate and excellent high temperature strength properties, it makes this an excellent material choice.
SiC can be used either as the main ingredient in shaped refractories, or added as an additive, to various other materials. SiC is often added to castables and bricks as an addition, to improve high temperature strength and thermal shock stability; additionally it has excellent slag resistance properties as well as protective oxidation. Incorporating SiC into clay refractories increases their chemical and slag resistance as well.
Porous SiC can function either as a resistor or an insulator depending on its makeup and additives; by adding acceptors (such as C, Si and Al) accepting can lower resistance while adding donors (like N2) will increase it.
