2: Introduction:

 Provides three special roll surface treatment methods to improve wear resistance, rust prevention, and service life of the roll surface.

3: Treatment Methods:

• Hard Chrome Plating.

• Plating thickness: 0.10-0.15mm.

• Plating hardness: HV800-1000.

• Features: High density, good wear resistance, improves negative electrode sticking, enhances rust prevention.

• Tungsten Carbide Spraying.

• Spraying thickness: 0.15-0.20mm.

• Spraying hardness: HV1050-1300.

• Features: Extremely high wear resistance and compression resistance, increases single grinding service life of the roll.

• Titanium Nitride Ion Implantation.

• Ion implantation layer thickness: 0.003-0.005mm.

• Surface hardness: HV2000-2200.

• Features: Higher hardness and wear resistance, further increases single grinding service life of the roll.
