DEVICE FOR SCALE REMOVING FROM STRIPS IN FINISH MACHINES Russian patent published in 2009 - IPC B21B45/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to strip finish machines, mainly to cutting machines installed in sheet finishing workshops or compartments of cold or hot rolling shops. The device for scale removing includes bottom backup and two top bending rolls. The rolls are installed on common support framework. The axis of bending roll being the first in finishing direction is located in the same vertical plane as the axis of the bottom backup roll. The second bending roll is installed behind the first one but at higher level. The bending rolls include axis where bearing sleeves are fixed. The bearing sleeves are coated with protective material. The electro-magnetic induction coils are permanently installed between bearing sleeves. They are mounted in circular metal enclosures covering axis and being fixed to bridge-type beams. They are installed on bearing assemblies bodies of bending rolls.

EFFECT: invention ensures strip finishing quality improvement, reduced number of rejected strips as second-rate quality or fully rejected, increase of accepted metal output and reduction of unscheduled downtime of equipment.
