Specification :

The guide roll made of TiC-based Cemented Carbides are the main consumptive parts, completed together with cemented carbide roll-rings in rod and wire milling in steel industry to ensure that the heated steel can be exactly guided into roll groove to prevent steel winding and tail swing.

TiC-based Cemented Carbides and their mechanical properties

Grade Main Components Density
g/cm3 HRA hardness (20.C) N/mm2
Transverse Rupture Strength
(20.C) KN/mm2
Youngs modulus Coefficient of thermal expansion 10-6 Applications
HTN-1 (Ti,W)C - Ni 6.40~6.70 e84.5 e1500 370 7.0 Guide roll
HTN-2 (Ti,W)CN- Ni 6.35~6.55 e83.0 e1600 360 7.0 Guide roll

Features:

Excellent crack resistance.
Good self-lubrication ability and low friction factor
Good wear and corrosion resistance
Resistance to thermal impact better than that of alloy steel, with a life time 20~50 times that of the latter.
Non-magnetic, not easy to be adhered by metal.
Smaller specific gravity, good acceleration property, prolonging bearing performance life.
