Applications
Silicon carbide ceramic rollers/tubes/pipes/rods are mainly used in high-temperature industrial scenarios. KCE® SIC Roller bars are used for transmission support in high-temperature roller kilns. The industries of application include technical ceramics DPF, Sintering process for materials such as positive and negative electrode materials of lithium-ion and lithium-ion batteries, electronic ceramic powders, sanitary ware, daily-use ceramics, magnetic materials, refractory materials, etc.
Advantages
With its characteristics of high temperature resistance, corrosion resistance, and good thermal conductivity, they are used in ceramic kilns to increase production capacity. Their corrosion resistance can extend the service life of equipment and reduce operating energy consumption.
