How to Choose the Right Ceramic Fiber Board for Your Furnace

Choosing the right ceramic fiber board is critical for maximizing energy efficiency and furnace lifespan. This guide will walk you through three key factors.

1. Temperature Grade: Match Your Process

• 1400°C – 1500°C: Suitable for heat treatment furnaces, annealing lines, etc.
• 1600°C – 1700°C: For ceramic kilns, sintering furnaces, metallurgical processes.
• 1800°C – 1900°C: For specialty applications like advanced ceramics and fiber optics.

2. Density & Strength: Balance Insulation with Durability

Density affects both mechanical strength and thermal conductivity. Our boards are available in a range of densities to suit different applications:

• Lower density: Provides better insulation, suitable for back-up layers or low-stress areas.
• Higher density: Offers greater strength and erosion resistance, ideal for hot face linings in demanding conditions.

We can recommend the right density based on your specific furnace type and operating environment.

3. Installation & Chemical Compatibility

Installation requires careful alignment to avoid gaps. For chemical compatibility, our boards resist most furnace atmospheres, but please consult us for aggressive environments.
