IThe SIROLLCIS Edgewipe is a flexible system
that incorporates all the necessary features for
effective control of Stip Edge dryness.
In most cases where coolant is carried over to the exit
side of the mill, standard air blow-off systems remove
excess fluid from the top and bottom surfaces of the
strip but not from the extreme vertical edges. Based on
experience and a sound understanding of the rolling
process, we provide a flexible control scheme
incorporating all the features necessary for effective
control of strip edge dryness.
Although only introduced in 2004, this product already boasts a number of successful reference sites.
Strip dryness is achieved by blowing the beads of fluid off
the strip edges and removing it completely by drawing the
resulting plume of fluid through an air mover away from the
strip. This prevents residual coolant migrating into the body of
the coil causing downstream quality problems.
The industrial PC based control system operates a mechanism to
dynamically position the blow-off jets and suction ducts in the
correct position to remove the bead of fluid that forms on the
edge of the strip as it leaves the roll bite. This mechanism
operates continuously via an infra-red tracking system.
