Description of VATHARD
By an unique open arc bulkwelding process an extremely hard complex chromium carbide deposit is welded to a mild steel base plate. After hardfacing the wearplate is formed by plasma or waterjet cutting according to drawing. The visible cracking which is limited to the hard surface layer is a characteristic of this type of product.
This hardplate is recognized throughout industry as the one which produces the hardest wearing plate currently available.
Upon request precise waterjet cutting is applied on screens.
Applications of VATHARD
Chutes, liner plates, deflectorplates, bunkers, hoppers, crushers, feeder throughs, fan linings, screens, cyclones, pulverizers, tubes, dredger suction mouths, excavators, bucket teeth, dredgepump parts, blast furnace bells, palm oil expeller screws, etc.
