Plasma Hardfacing Applications in Paper Machinery

The paper manufacturing industry relies heavily on equipment that operates under continuous friction, humidity, pressure, and chemical exposure. Key components such as press rolls, doctor blades, and scraper systems experience significant surface wear over time, which can lead to production instability, increased maintenance, and costly downtime. Plasma hardfacing (PTA welding) has become a powerful engineering solution for enhancing the durability, performance, and service life of paper mill machinery. With advanced surface-engineering capabilities, FNS Pipeline Technology Co., Ltd. provides reliable plasma hardfacing services that help mills maintain stable, cost-efficient production.

1. High Wear-Resistant Coating Preparation

Plasma hardfacing enables the deposition of high-hardness, wear-resistant alloy coatings onto critical paper machine components.

These coatings—typically composed of carbide-reinforced or corrosion-resistant alloys—are applied to components such as:

• Press rolls
• Doctor blades
• Scraper blades
• Guide elements
• Material-handling parts

The resulting protective layer significantly reduces abrasive wear, extending equipment lifespan, minimizing downtime, and reducing replacement frequency.

2. Damage Repair and Surface Restoration

Over time, components in paper machinery often develop scratches, scoring, pitting, or thermal wear. Plasma hardfacing offers an effective method to restore damaged areas by depositing new alloy layers precisely on the worn surfaces.

This repair process:

• Restores original component geometry
• Recovers mechanical performance
• Prevents premature component replacement
• Supports long-term equipment reliability

FNS specializes in PTA-based refurbishment that meets strict operational tolerances.

3. Material Upgrading for Older Equipment

Older paper machinery may be built with lower-grade materials that struggle to withstand modern production demands. Plasma hardfacing enables cost-effective material upgrading, improving resistance to abrasion, chemicals, and temperature.

By applying high-performance alloy layers, components can be upgraded without full replacement, ensuring stronger durability and better adaptability to harsh processing environments.

4. Equipment Performance Improvement

Beyond repair, plasma hardfacing can be used strategically to enhance equipment design.

Specialized coatings can:

• Reduce friction coefficients
• Improve surface smoothness
• Increase resistance to chemical attack
• Improve fiber flow and material movement
• Enhance energy efficiency

These improvements directly contribute to better product quality, consistent machine performance, and higher production output.

5. Cost Reduction and Higher Operational Efficiency

Compared with replacing entire components, plasma hardfacing offers a highly economical maintenance solution. It reduces:

• Replacement costs
• Downtime for repairs
• Long-term wear-related losses
• Equipment scrap rates

For paper mills, this means lower operational costs, greater sustainability, and improved production stability.
