HSS
High-Speed Steel Rolls can be used on all stands of bar and wire rod mills, in particular on the finishing mill, including dog-bone and slitting stands on slitting process.
Description
> An increase in roll lifetime compared with standard cast iron rolls (3-5 times bigger) thanks to longer groove life time (2-3 times) and reduced redressing thickness (-10 to -50%).
> Reduction of heat cracks and mechanical impact cracks compared with tungsten carbide rings.
> Increased rolling campaign time.
> Better surface finishing.
