Paper Roll Tungsten Carbide Coatings

The fibrous quality of paper and the acidic nature of ink results in high corrosion and wear to components in the paper industry. Endurance provides Tungsten carbide coatings in India that enhance the ingredients used in the paper industry.

Our specialized coatings, such as Enduro 411, and Enduro 920 for the Paper industry, improve the endurance quotient of your components from wear and tear issues like corrosion, unwanted build-up and slippage wear.

THE SHIELD OF ENDURANCE IMPACT

The first step in reducing wear and increasing endurance is to understand the process of component wear. Understanding the problem helps identify the metal coating that will protect and improve its endurance.

Ensuring benefits of lower downtime, higher reliability of components and longer service life.

Our HVOF/HVAF coatings deliver numerous benefits starting with enhancing the endurance and wear resistance of critical paper rolls. They ensure the long-life serviceability of your components optimizing their continual use. Our HVAF coatings provide paper roll applications with numerous qualities.

  • High hardness – Our coatings can manage the variable hardness range of tungsten carbide coating between 1050 – 1200 HV to 1400 – 1600 HV on-demand.
  • High ductility – Since HVAF coatings have low oxide content, it results in low stress and high ductility.
  • Low porosity – Our coatings have a porosity of less than 0.3% which ensures fewer defects.
  • Manageable as-sprayed roughness – Our carbide coatings achieve a roughness of 1, 2, or 3 Ra µm set by the order.
  • Low cost – Our state of art US equipment provides the highest quality standards to the Indian paper Industry. The high productivity of our thermal spray coating equipment combined with low operative expenses results in lower-cost benefits that we pass on to our customers.

EnduroMax 411 and EnduroMax 438 are our specialized coatings for the Paper industry that improve the endurance of your roll and cylinder components against corrosion, unwanted build-up, slippage and regular wear and tear.

Calendar roll tungsten carbide coating

We undertake thermal spraying of tungsten carbide coatings onto new and repaired calender rolls on our shop floor. Calendar rolls reduce thickness, enhance surface properties and polish whatever material is being rolled.

We produce customer-specified coatings for the calendar rolls. We can achieve various types of surface hardness and roughness via varied spray techniques and different materials. We provide spraying, grinding and polishing services on-demand.

Tungsten Carbide Coatings for Doctor blades

The doctor blade of a paper machine must maintain uniform contact and loading across the roll width across its machine lifetime. Hence, it is imperative to choose a durable holder and robust doctor back design for optimum performance.

Tungsten carbide sprayed blades prevent damaging the wear-resistant surface of most ceramic rolls and keep the roll surface clean. Combine a non-wearing doctor blade with a non-wearing ceramic-coated roll for long-lasting product life.

Choose the highest quality of HVOF tungsten carbide coating for the tip of the blade with about 80 to 90% actual carbide making. The environment and the subsequent level of corrosion resistance required will dictate the choice of material.

Dryer cylinders, after dryer cylinders, and after coating stations with coating rings on the cylinder surface are other areas of use for Carbide coated doctor blades.
