5/25/2011 - Rolls have been installed at ThyssenKrupp Nirosta
JVM wringer rolls with special fibre coverings
JVM Rolls have been installed behind the degreasing unit and downstream of the passivation bath in the No. 1 bright-annealing line 1301 at ThyssenKrupp Nirosta. All existing rubber rolls in this application have been replaced by JVM Rolls. JVM Rolls achieve under all operating conditions optimal results and excellent surface quality conditions even with thicker gauge strip. They achieve such a good wringing result that the second pair of rolls in the original double pair arrangement - which was permanently running in the past - could be taken out of operation.
For future installations of special fibre wringer rolls this means that wherever double or triple arrangements were necessary in the past, a single JVM Roll pair will be sufficient to reliably free the strip surface from water. Whereas rubber or polyurethane covered rolls had to be frequently replaced, the special fibre rolls have proved to have a roll life of several years. Despite the higher cost per roll, the total cost of ownership is clearly more favourable than that of rubber or polyurethane coated rolls. The considerable amount of labour required for checking, reworking and changing the rolls has been reduced to virtually zero.
