Scope of HSS Roll Application
Our high-speed steel rolls are widely used in:
Finished frame (high-speed steel roll), front frame (high-speed steel roll), slitting frame (high-speed steel roll), pre-slitting frame (high-speed steel roll).
High-speed wire mill pre-finishing unit. Finishing Mill for Hot-rolled Narrow Strip Mill.
Finishing stands for spring flat steel mill and small section mills such as angle and channel steel.
>high and uniform hardness;
>high resistance to wear abrasion;
>high resistance to adhesivenessby surface oxide layer;
>high resistance to heat cracksand thermal stress;
>fine and uniform structure overthe external layer.
>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.
> lncreased rolling campaign time.
Better surface finishing.
Advanced Manufacturing Processes and Implementation Standards
Product design → roll billet design → roll billet manufacturing → roll billet acceptance → annealing → rough turning → ultrasonic flaw detection → high temperature quenching → low temperature tempering → ultrasonic flaw detection → finishing → ultrasonic flaw detection → roll body grinding → roll number → inspection → cleaning → packaging→ storage → shipments→ inspection → use and maintenance →exchanged → improvement of design.
It can be seen from the flow chart that roll manufacturing forms a closed-loop system from product design, production manufacturing, use and maintenance, and improvement design, and the quality of roll is constantly improving.
