How to maintain the screw and screw conveyor of the paper machine?

The spiral surface coating is repaired using the multi-layer wood plasma surfacing technology, which uses a plasma power source to form a high-temperature arc column on the damaged surface, melting the composite coating of tungsten carbide alloy powder, thereby repairing and restoring scars on the mechanical surface.

Plasma surfacing technology has the following advantages for workpieces.

①Restore the original size of the workpiece, restore the workpiece, refurbish and reuse.

②The special powder used for welding technology can make the repaired part more wear-resistant and corrosion-resistant.
