Silicon carbide kiln furniture is a kind of equipment used for high temperature firing of materials. It is mainly made of silicon carbide material. Silicon carbide kiln furniture is currently the preferred material for new energy-saving and lightweight kiln shelves for high-end porcelain pieces or advanced kilns.
Silicon carbide kiln furniture materials are generally divided into three types. They are reaction sintered silicon carbide(RBSIC), recrystallized silicon carbide(RSIC) and silicon nitride bonded silicon carbide(NSIC). Please contact us and Kerui will help you design and select the type and material of kiln furniture that best suits your project.

Silicon carbide kiln furniture is generally used as kiln frame kiln furniture. For example: silicon carbide column, silicon carbide beam and silicon carbide plate. Kerui rationally combines them to form the load-bearing structure of the kiln car, which supports and protects the product during the ceramic firing process. The following are the best-selling silicon carbide kiln shelves of Kerui. You can also leave us a message on Facebook or email about the type and technical specifications of the kiln furniture you want. Our business manager will give you a quote within 12 hours.
The main advantages of Kerui Group silicon carbide kiln furniture are high temperature resistance, high strength, wear resistance, corrosion resistance, etc. During high temperature firing, silicon carbide kiln shelf can maintain stable performance without deformation and cracking. In addition, silicon carbide kiln shelf also has the advantages of high thermal conductivity and long service life. Therefore, customers can effectively improve production efficiency and product quality by using it.
Silicon carbide shelf board: it is mainly suitable for firing sanitary ceramics, daily ceramics and electric ceramics in tunnel kilns, shuttle kilns and roller kilns at 1450 ℃(2642℉). It is used together with silicon carbide columns. The use of kiln furniture for sale made of this material can save more than 30% of energy.
Basin board for sanitary ware: we mostly use it for firing sanitary ware. It can also be designed and made in special shapes.
Fish-shaped board: the plate bracket in the kiln for firing daily ceramics can save more than 30% of energy. It is mostly used in clean fuel kilns.
Split bracket: customers can use it to fire plate products. The kiln loading steps of the split bracket are simple and easy to operate.
Energy-saving sagger: it is mostly used to fire various small ceramic pieces and powdered products and it is convenient to hold. It is also easy to load the kiln.
Refractory pillar series: we use it together with the shelf pad. It can be used for firing sanitary ceramics and daily ceramics in tunnel kilns and shuttle kilns. The structure of silicon carbide pillars is stable and has a long service life.
Kerui’s silicon carbide kiln furniture is widely used in electrical porcelain, daily porcelain, electronic ceramics and magnetic materials. You can also see them in various ceramic kilns in the steel, cement, glass and other industries. In addition, we also produce refractory bricks, insulation bricks, ceramic fiber products, castables, refractory mortar, high temperature fire cement, etc.
Our factory has an annual production capacity of 250,000 tons of refractory materials. Moreover, we have a complete refractory production line. Kerui’s technical engineers can provide different formulas and processes to design products according to different kiln usage conditions. In other words, we have the ability to help customers greatly improve the service life of materials and reduce customers’ use costs. Providing customers with satisfactory services is our unchanging purpose.
