Processing Hardfacing
Extends the Life of Logging, Lumber
and Paper Processing Equipment Equipment
used for logging, lumber and paper processing is exposed to a tremendous
amount of wear and tear and the use of Postalloy hardfacing alloys will
dramatically improve their wear life, and therefore, length of
service. Impact subjects the part to immediate and rapid crushing
forces that usually result in deformation and spalling of the metal
surface. Compression, which generally means that the force is
applied for a longer period of time, results in mostly abrasion.
Grinding abrasion occurs when abrasive particles are ground between two
surfaces under pressure, causing the abrasive particles to fracture and be
crushed. This increases wear rates by comparison with rounded
abrasives. Alloys to resist wear and abrasion must be both hard and
tough, since in most cases, wear is caused by multiple factors.
Suggestions include chromium carbide and complex carbides.
No
single procedure or hard surfacing overlay will solve all the
problems. Postle Industries, a leading supplier of hardfacing
solutions, offers a complete range of flux-cored welding wires and welding
electrodes. We have the experience to recommend the right procedure
for any application involving the repair and rebuilding of equipment used
by the lumber and forestry industry. A well planned maintenance
program, emphasizing wear prevention by hard surfacing of worn parts will
result in increased production and more uniformly sized finished product,
less wear and tear on crusher components, reduce part replacement and
change outs, and a substantially reduced cost per ton.
