High-Strength Square Silicon Carbide Ceramic Protective Liner Plates (Multi-Plate Array Type)

High-Strength Square Silicon Carbide Ceramic Protective Liner Plates (Multi-Plate Array Type)

Product Introduction

This product is a high-strength square silicon carbide (SiC) ceramic plate meticulously manufactured using a reaction sintering process. Silicon Carbide (SiC) is recognized as a top-tier engineering ceramic, renowned for its ultra-high hardness approaching that of diamond, exceptional high-temperature resistance, and outstanding thermal shock resistance. The product features a standardized square design, allowing for flexible assembly into large rectangular arrays. Its flat surface, compact structure, and dark gray color signify industrial-grade sturdiness and reliability. Designed specifically to withstand extremely harsh operating conditions, it provides comprehensive protection solutions.

Primary Applications

• Equipment Wear Protection: Widely used in industries such as thermal power generation, mining, and steel plants as liners for bunkers, chutes, and pneumatic conveying pipelines, as well as protective plates for fan blades.

• High-Temperature Furnace Linings: Serves as furnace wall linings, hearth plates, etc., capable of stable long-term operation at temperatures up to 1650°C.

• Heavy Machinery Impact-Resistant Components: Can be used in key parts of engineering machinery and material handling equipment to disperse and resist strong impact and abrasion from materials.

• Chemical Equipment Corrosion-Resistant Linings: Effectively resists the combined effects of acid/alkali corrosion and wear in harsh chemical environments.

Product Advantages

• Extreme Wear Life: Exceptional hardness provides wear resistance far superior to wear-resistant steel, significantly extending equipment maintenance cycles and reducing overall costs.

• Excellent High-Temperature Stability: Maintains strength at high temperatures, offers superior oxidation and creep resistance, outperforming ordinary metals.

• Superior Thermal Shock Resistance: Withstands rapid and severe temperature changes without cracking, ideal for applications with frequent thermal cycling.

• High Stiffness & Impact Resistance: High elastic modulus and compressive strength effectively disperse and absorb impact energy.

• Modular Design: Standard square plates facilitate easy installation and replacement, and can be combined to cover large protection areas.

Usage Instructions

1. Installation Preparation: Ensure the mounting surface is flat, solid, and free of oil, grease, and contaminants.

2. Fixing Methods: Bonding using high-strength, temperature-resistant inorganic adhesive is recommended. Alternatively, mechanical fixation using bolts and clamping plates can be employed. For array installation, appropriate expansion gaps must be left between plates.

3. Safety Warning: This product is extremely hard and brittle. Avoid violent impact on the edges with hard objects. Wear protective gloves during handling and installation to prevent cuts.

4. Custom Machining: All drilling, grooving, or other machining must be completed at the factory before shipment. Mechanical processing of finished products on-site by customers is strictly prohibited.

After-Sales Service

We provide a 12-month quality warranty from the date of shipment. For product failures due to material or manufacturing process defects under normal use conditions, we promise free repair or replacement. Lifetime technical consultation is available.

FAQ (Frequently Asked Questions)

• Q: Can these square plates be fixed directly onto equipment using weld-on studs?
  A: Absolutely forbidden. The high heat and stress from welding will instantly cause the ceramic plate to crack. Dedicated adhesive bonding or mechanical fixation solutions must be used.

• Q: What are the main differences compared to alumina ceramic liner plates?
  A: The main advantages are higher hardness (increased wear resistance), better thermal conductivity (faster heat dissipation), and superior thermal shock resistance. Service life is typically longer, especially in high-temperature, high-impact environments.

• Q: Can you customize non-standard sizes if needed?
  A: Yes. We support custom manufacturing based on customer drawings, including dimensions, thickness, and mounting hole patterns. Please provide detailed technical requirements when inquiring.
