Tungsten Carbide Guide Roller

  • Titanium carbide has proved to be a cost-effective material for the manufacture of guide roller for wire rod mills, having low density, excellent anti-oxidation and wear resistance, coupled with relatively good resistance to thermal shock. TiC hard-metals have a relatively simple metallographic structure, but for quality control, the grain size and porosity must be controlled. In particular,porosity is the main quality problem since even vacuum sintering cannot completely overcome the problem of oxygen pick-up. However, the hot isostatic pressure sintering process (HIP), introduced in the late 1980s, significantly improved the final quality of TiCs, by solving the porosity problems.
