Miller™ Tungsten Carbide Rolls

Description

Tungsten carbide rolls is also well known as tungsten carbide cold roll, which is mainly used to produce smooth wire or ribbe wire for the construction reinforcement field.

Benefit from the application of the most modern production methods and the use of the high quality materials, as well as our most experienced employees who manufacture the tungsten carbide rolls, Miller defines a new standard in wire reduction. and increased wire quality through improved surface finishing and rib geometry.

Benefits of using tungsten carbide rolls:

• Tungsten carbide rolls can last up to 50 times longer than conventional, hardened tool steel rolls
• Guaranteed product performance, save more time and work efficiently
• Solves excess wear problems on any roll section of the mill
• Fewer changeovers, due to excessive wear on hardened tool steel rolls
• Holds tighter tolerances on tube and pipe
• Tungsten carbide rolls should be considered, when high footage/tonnage is required from any one particular size
• Eliminates pick-up to give tube and pipe a better surface finish
• Rolls can be solid carbide on smaller mills or carbide-inserted for larger rolls
• Miller’s design expertise can assist in cost justification
• Drag finished roll surface for the best wire quality
• Grinding of all profiles and markings
• Optimum chemical composition and physical properties of carbides
