Silicon Carbide Kiln Components

SiSiC Beam

Type Beam

RBSiC / SiSiC beams are used as load-bearing kiln furniture in tunnel kilns, shuttle kilns and other industrial kilns. They provide high-temperature strength, excellent thermal conductivity and long service life, making them suitable for supporting sanitaryware, tableware, ceramic products and other fired materials.

Key Advantages

High load-bearing capacity at elevated temperatures
Excellent resistance to deformation during long-term firing
Good thermal conductivity for improved kiln efficiency
Suitable for tunnel kilns, shuttle kilns and industrial kiln structures
Long service life under continuous high-temperature operation
