Application of Graphitization Furnaces in the Abrasive and Grinding Too"&"l Industry

Graphite materials have important applications in the abrasive and grinding tool industry, mainly used in the manufacture of diamond sintering molds, grinding wheel dressing tools, etc. These applications have special requirements for "&"the performance of graphite materials.

Main Applications

• Diamond Sintering Molds: Used for high-temperature and high-pressure sintering of synthetic diamonds.
Graphite molds maintain sha"&"pe stability under high temperature and pressure, and do not react with diamond. **Wheel Dressing Pen:** Used for dressing diamond and CBN wheels. Dressing pens require high hardness and high wear resistance. **Wire Drawing Die Core:** Used for drawing "&"metal wires. Graphite core molds have self-lubricating properties, reducing friction.

Performance Requirements

Performance requirements for graphite in abrasives:

• High hardness: Resists "&"wear and extends service life.
• High wear resistance: Remains stable under frictional conditions.
• High thermal conductivity: Dissipates heat quickly and prevents localized overheating.
• Sufficient strength: Withstands mechanical stress during processing and use.

Graphitization Process

The graphitization temperature of graphite for abrasives is typically 2500-2800℃. The key points are: A moderate degree of graphitization is sufficient; extremely high purity is not required as in semiconductor-grade graphitization. The balance between strength and graphitization degree is crucial—excessive graphitization can act"&"ually decrease strength. High density and low porosity are required. **Summary:** The key to graphite used in abrasives is hardness and wear resistance; purity requirements are relatively lenient. The graphitization process needs to find the optimal "&"balance between graphitization degree and strength.")
