Cemented carbide rolls have good heat conductivity and they are featured by small hardness decrease under high temperature condition, thermal fatigue resistance, good wear resistance and high strength etc., which are not possessed by other materials. 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.
Tungsten carbide rolls can last up to 50 times longer than conventional, hardened tool steel rolls
Tungsten carbide increases the tooling life before regrinding, lasting up to 10 times longer than conventional, hardened tool steel rolls
Guaranteed product performance
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
Roll-Kraft’s design expertise can assist in cost justification
