Silicon Carbide Guide Rails for Kiln Cars

What is Silicon carbide guide rails?

Silicon carbide guide rails for kiln cars are generally high-end refractory components used in the high-temperature kiln industry, primarily for supporting and guiding the kiln car. Here are the key points:

1. Material Characteristics of Silicon carbide guide rails

High-Temperature Strength: Silicon carbide maintains high strength at temperatures between 1400°C and 1600°C and resists deformation.

High Wear Resistance: Suitable for the long-term friction of kiln cars, with a lifespan far exceeding that of ordinary clay brick or high-alumina brick rails.

Excellent Thermal Shock Resistance: Silicon carbide is less susceptible to cracking due to the frequent movement of kiln cars in and out of the kiln and the resulting sudden temperature fluctuations.

High Thermal Conductivity: Ensures rapid and uniform heat transfer, reducing energy consumption.

High Corrosion Resistance: Resists corrosion from acidic and alkaline atmospheres and some slag.

2. Applications of Silicon carbide guide rails

Ceramic Kiln Car Rails: Suitable for household ceramics, architectural ceramics, refractory tunnel kilns, and roller hearth kilns.

Metallurgical Industry: Sintering kilns and annealing lehrs.

Other high-temperature kiln car rails: glass and chemical sintering kilns.

3. Advantages of Silicon carbide guide rails

Extends rail replacement cycles, reducing maintenance costs.

Maintains kiln car operating stability, reducing deflection and jamming.

Can replace traditional steel and clay rails, especially advantageous in high-temperature, heavy-load environments.

4. Common Specifications of Silicon carbide guide rails

Straight, square, or “T-shaped” cross-sections, custom-made to suit the kiln car design.

Lengths generally range from 500 to 1500 mm, with cross-sections ranging from 50×50 mm to 150×150 mm.
