Audited Supplier
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. When choosing the right carbide rolls for your production needs, it's important to evaluate the load and speed requirements of your manufacturing process. The load refers to the amount of force that the rolls will need to withstand during operation, while the speed refers to the rotational speed of the rolls. Both of these factors can impact the durability and performance of the carbide rolls. Miller can help you determine the load and speed requirements for your specific production needs and recommend the appropriate carbide roll.
