Description
GENERAL CHARACTERISTICS:
Our unique, Astro Tungsten Carbide Electrode consumable has crushed or spherical carbides in a 6mm tube high grade nickel alloy matrix and binder. The dense, wear resistant properties of the finished surfacing are assured, by maintaining both the ratio and combination of carbide sizes throughout the length of the rod.
TYPICAL APPLICATIONS:
Astro’s tungsten carbide can be used under the most severe conditions in many industries to achieve longer life against abrasion, less down time and to serve as a protective surface which can be rebuilt again and again when necessary.
FEATURES:
- Reduced distortion and oxidation of base metal
- Dense distribution of carbide particles
- Corrosion resistant matrix
- Faster coverage rates
- Easy repairs
OIL INDUSTRY:
On stabilisers, drill strings, bits and finishing tools
DREDGING:
On cutter teeth, dragging teeth and pump castings
CEMENT AND BRICK:
On augers, extruder and feed screws, deflection cones, pump rings and liners
ALLOY AND STEEL FOUNDRIES:
On sand and coal mixer paddles, guides and raking equipment
PAPER:
On mixers, compression screws, pulverisers and shredders
MINING AND POWER:
Between coal crusher teeth, on rotating bucket teeth, and pulverised fuel system
CLAY AND CERAMICS:
On wetting and mixing units, grinding cylinder scrapers, rakes and crusher teeth
PLASTICS AND RUBBER:
On mixer/extrustion screws and liners, rotors and spares
ARC WELDING PROCEDURES:
As with all surfacing products, the removal of any scale, rust or oxidation from the base material by machining or grinding is essential.
The thickness of each layer should not exceed 3mm. (maximum 2 layers, 6mm).
