Roll Grinder, Modernization, Retrofit, Paper Machine, Steel Industry

Sba received two package orders from ArcelorMittal Asturias.

The first order is part of a modernization program of the complete hot mill roll shop. SBA will upgrade three roll grinders one by one. A Waldrich roll grinder used since 1992 for backup rolls and roughing mill work rolls will be modernized especially on the roll support side. This also requires a Morgoil lubrication system and lifting tables to accommodate various sizes of BUR chocks.
Modernizations are also required for two Waldrich grinders in the finishing mill to grind work rolls together with chocks. As a special feature Sba will install chock rotating and supporting technology.

The second order is placed for the cold mill roll shop and covers a major upgrade of a Farrel grinder for backup rolls and a full modernization of a Waldrich work roll grinder.

All orders cover a complete replacement of obsolete LT and KPM control systems by our latest SBA Grinder Control SINUMERIK 840Dsl, complete new electrics and integration of measuring systems like • Profile measuring and correction during grinding • Eddy current measuring • Ultra sonic measuring • Surface wave measuring.

We would like to thank the Acrelor Mittal team for trust in SBA.
