Applications
Silicon carbide ceramic kiln furniture pillars/columns are mainly used in high-temperature industrial scenarios. They are suitable for load-bearing structures in shuttle kilns, tunnel kilns, double-layer track kilns, and various high-temperature kilns.
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.
