SIROLLCIS HM Work Roll Lubrication    Lubrication system for work rolls to reduce conversion cost and improve strip quality

The SIROLLCIS HM Work Roll Lubrication package is dedicated to reduce roll wear and friction of the work rolls in the finishing mill stands.

Work-roll lubrication system The challenge Surface defects on work rolls in the finishing mill stands are due to rolled-in scale and peeling of the work-roll surface. The roll wear has a high impact on conversion costs and on limitation in scheduling. The high pressure which is necessary without lubrication affects the friction of the work rolls.

Our solution

By installing the barrel lubrication package on works rolls, surface defects are avoided and roll wear is reduced. The application of lubrication media onto the work rolls is dedicated to reduce friction. Most of the equipment used for work-roll barrel lubrication is mounted onboard the finishing-mill stands, close to the work rolls, such as wipers, spray nozzles and mixing unit. Additionally, external equipment such as lubrication unit, electrical control (automation, visualization, data-processing) and supplies of air, water and oil is installed. The entry wiper design for roll gap lubrication is a special sandwich-composition to get best sealing conditions. The sealed entry roll gap ensures a low consumption of oil. The lubricant is applied at the entry side of the finishing mill stands. A special nozzle arrangement and an optimized nozzle design ensure optimum consumption and distribution of the lubricant. With standardized interfaces and flexible communication options it is easy to integrate the roll gap lubrication into to automation of an existing plant.
