Rolls for Paper, Rubber, Flour, Plastic etc. are made with the following composition. The chill depth of these rolls are generally in the range of 12-15 mm. However, in special cases higher chill depth can be given. The hardness of such rolls ranges between 60 to 75 Shore 'C'. The above rolls have very good wear and corrosion resistance with uniform chill depth, soft core and journals. Hollow rolls are pressure tested hydraulically for checking and unsoundness of roll.
