Tungsten Carbide (TC) Rings
Tungsten Carbide roll (ring) or TC ring is a tool material which contains Tungsten Carbide and Cobalt. These rings are used for extended life in applications where long rolling campaigns are required. These rings are primarily applied in high-speed wire production lines, seamless pipe stretch reducing mill and three-dimensional rolls for cold-rolled ribbed steel bar. Their extreme hardness makes them suitable for wire rods finishing blocks and some shaping applications. They have a mass diameter ≤480mm and thickness ≤130mm.
Characteristics of Tungsten Carbide
- Tungsten Carbide is the most wear resistant metal on earth
- Due to their extremely high hardnesstungsten carbide rings can keep their shape and luminescence in tact longer for any other ring on the market.
- Compared with other materials, TC is much better in terms of heat-resistance, wear-resistance and strength.
- These rings are highly efficient and have a long service life.
Applications
- Bar & Wire rod mills
- Hot Strip Mill, Cold Strip Mill, Section mill, Plate rolling mill, Seamless Pipe rolling mill
- High-speed finishing mill roll sleeve
