HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment

For the work roll hot-grinding with contour com-pensation, the experimental results are summarized in Table 1. The comparison of profiles for the hot roll and cold roll (case HSS Roll 1-1) is also shown in Fig. 3 as an example. In the cold roll measurements, the work rolls were cooled as completely as possible such

Open the catalog to page 4. DIPROTEX Vitrified Bond CBN Wheel Vitrified bond, also called ceramic bond, has high bonding strength, hardness and rigidity. Vitrified bonded wheels have pores that allow the wheels to have good grinding ability. Diprotex designs the most suitable wheel for each application by adjusting pores and bond structure.

Cast and forged HSS rolls could not be finished conventionally to the required quality until recently. One reason for this is that conventional wheel bodies, made out of aluminum, steel or plastics, do not possess any damping properties and are therefore not suited for the finish grinding of very hard HSS rolls.
