Silicon Carbide (SiC) rollers are the core transmission components of roller kilns, widely used in the firing of architectural ceramics, sanitary ware, domestic ceramics, and electronic ceramics. Based on the manufacturing process, they are mainly classified into two types: Reaction Bonded Silicon Carbide (RBSiC) and Recrystallized Silicon Carbide (RSiC).
Type Comparison:
1. Reaction Bonded SiC (RBSiC):
Composition: Contains a small amount of free silicon.
Advantages: High density, high strength, and cost-effective.
Max Temp: Up to 1400°C.
Application: Ideal for medium-to-high temperature roller kilns firing tiles and domestic ceramics. Offers the best balance of performance and price.
2. Recrystallized SiC (RSiC):
Composition: High purity with almost no bonding phase.
Advantages: Exceptional high-temperature resistance and creep resistance (no deformation at high heat).
Max Temp: Up to 1650°C+.
Application: Perfect for high-temperature firing of sanitary ware and special ceramics where extreme thermal stability is required.
Key Features:
1. Superior High-Temperature Strength: Maintains excellent mechanical properties even at temperatures ranging from 1400°C to 1600°C.
2. Excellent Thermal Shock Resistance: Resistant to rapid temperature changes, preventing cracking or breakage during quick heating and cooling cycles.
3. High Wear Resistance: Extends service life and reduces maintenance costs in abrasive kiln environments.
4. Corrosion & Oxidation Resistance: Performs well in various kiln atmospheres, resisting chemical erosion.
5. High Dimensional Accuracy: Smooth surface finish ensures stable and precise transportation of ceramic products.
