Mill Roll Hardening Systems are becoming increasingly popular with the expanding development of cold mills which subject the rolls to high systems are used to obtain rolls with high strength and resistance to surface wear. Induction heating has greatly contributed to improvements in hardening depth, with subsequent improvement in distribution of residual stresses.
Construction. RV mills are of a very strong unitary construction with main body continuous welded in 10 mm plate. The large diameter (355 mm) rolls, one grooved and one plain, are machined from quality cast iron, precision balanced and mounted on 60 mm shaft and bearing assemblies with dual coil spring protection from foreign objects.
and P J Plastometer Hardness Scales Although the Durometer (Shore) A and D hardness scales are the most widely used in the polyurethane elastomer industry, the P J (Pusey and Jones) Plastometer is commonly used in the roll industry. In certain applications, such as paper mill rolls, the P J scale is used almost exclusively.
Selection of materials and roller roll surface hardness. Roll the choice of materials and work characteristics and damage roll form are closely related. Steel mill roll and have a larger impact force load, should have sufficient strength and hardness of the roll surface can be placed on second. Roughing mill roll should be chosen by special ...

Roll hardness is one of the most important parameters when deciding whether a paper roll is good or bad. A roll that is wound too softly can go out of round when handled. A roll that is wound too hard, on the other hand, can crack during transportation. These variations are difficult to detect.

be discussed, as well as case histories illustrating the roll cover''s benefits to the papermaker. INTRODUCTION Paper mills have been using rubber covered rolls in different stages of the paper making processes for many years. The success of rubber roll covers depends on optimal physical and mechanical properties of the cover composition.
Today all roll makers and almost every customer roll shop is using the Equotip system for various hardness checking. Scleroscope Shore instruments do not exist anymore. Please note; The different hardness units are not linked to the normal metric system and are only related to its own instrument.

In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
