Rehardening of used rolls
The lifetime of surface hardened rolls depends on thickness of the hardened layer. When this layer is worn out, the roll has to be taken out of production process - trough its diameter and other performances are still suitable.
By rehardering, the roll »life« can be extended
With a special technological process, the used roll can get a »second life«. In the process of rehardening , the surface layer regains the required hardness without influencing other characteristics of the roll.
The rehardened roll keeps the dimension and other parameters of the former roll. The »second lifetime« of such roll is equivalent to that of a new roll, but the cost are lower.
