SiC Refractory Support

SiC Refractory Support
Silicon Carbide Support for Heat Treatment Furnace

SiC Refractory Support is a high-performance silicon carbide ceramic component designed for use inside heat treatment furnaces and high-temperature industrial furnaces. It is commonly used as a support, setter, tray support, beam, rail, or fixture to hold workpieces during heating, carburizing, nitriding, tempering, annealing, and other thermal processes.

Silicon Carbide offers excellent heat resistance, high mechanical strength, good thermal shock resistance, oxidation resistance, and dimensional stability under high-temperature conditions. Its high thermal conductivity also helps improve heat distribution inside the furnace, supporting more stable and efficient heat treatment performance. SiC is widely used for kiln/furnace furniture because of its thermal shock resistance, low thermal expansion, and efficient heat distribution.

Key Features
High Temperature Resistance
Suitable for continuous use in high-temperature furnace environments.

Excellent Thermal Shock Resistance
Withstands rapid heating and cooling cycles better than many conventional refractory materials.

High Mechanical Strength
Designed to support workpieces under high-temperature operating conditions.

Good Dimensional Stability
Helps reduce deformation, bending, and distortion during furnace operation.

Oxidation & Wear Resistance
Provides longer service life in demanding heat treatment applications.

Efficient Heat Transfer
High thermal conductivity supports uniform heating and improved furnace efficiency.

Applications
High-temperature Heat Treatment Furnaces (Annealing, Hardening, Carburizing, Nitriding)

Tunnel kilns, shuttle kilns, and roller hearth furnaces

Support beams, bats, and kiln furniture for technical ceramics, powder metallurgy, and electronics manufacturing
