Lz30/Yg15 Finished Tungsten Carbide Roller High Elastic Modulus
Multipurpose Usage
Product Description& application:
Tungsten carbide cold rolls is the main products of LIZHOU, main market is India, Europe, Amecia, even quote base on the tender, and cooperate with local agent. Our rolls include PR,CA,RT, RO,FO type.
Also could make it as per customer requirements.
The material of rolls blanks we used are sintered in HIP furnace, 100% virgin material.
Tungsten Carbide Roller as the characters of high wear resistance, high corrosion resistance and good compressive properties which is an important parts in the steel bar and wire rod rolling. The rolls are primarily applied in high speed wire line, Kocks three roll mill, seamless pipe stretch reducing mill, three dimensional rolls for cold-rolled ribbed steel bar, and composite roll for hot-rolled bar screw thread steel etc.
Recommended Grade: LZ30/LR30/40/45
