Description
RBSiC/SiSiC/SSiC components for energy-saving kiln furniture mainly includes Silicon carbide beams etc.
KCE® Silicon carbide beams are formed by extrusion molding and high-temperature sintering. beam products can be made into concave beams (also known as U-shaped beams) or L-shaped beams according to customer needs. Machining can also be performed on the crossbeam, such as holes, long holes, or slots.

Applications
Silicon carbide ceramic (SiC) beams are mainly used in high-temperature industrial scenarios.
Typical applications include load-bearing structural components for refractory materials on the roofs of shuttle kilns, tunnel kilns, roller kilns, bell jar kilns, and other industrial kilns, as well as kiln furniture supports for carrying products on kiln cars.
Industry applied: sintering process of technical ceramics, electronic ceramic powder, sanitary ware, daily ceramics, electric ceramics, refractory materials, foam ceramics, lithium battery anode and cathode materials, etc.
Advantages
KCE® silicon carbide pillars/columns have excellent high-temperature flexural strength, thermal shock resistance, oxidation resistance, and high bearing capacity. They do not deform after long-term use. They have good thermal conductivity, long service life, energy saving and consumption reduction.
