INTENDED USE

The WILCO Model 1250 Automatic Brush Descaling System is intended for continuous inline descaling and aggressive brush cleaning of hot-rolled steel wire rod.  

SYSTEM CONFIGURATION

The Descaling System consists of a 3-sheave Scale Breaker and Automatic Rod Brusher mounted on a common base plate. The Automatic Rod Brusher consists of 2 halves each with 4 brushes oriented 90 ° to the rod direction. The brushes contact the rod at one of three selectable brush pressure settings. The controls automatically maintain that pressure.

SYSTEM OPERATION

In operation, the rod is pulled through the Scale Breaker by the wire drawing machine. 80-90% of the scale broken loose falls from the rod and collects in the Scale Breaker cabinet. The remaining 10-20% is loose but clinging to the rod due to static charge.

The Automatic Rod Brusher removes this loose scale as well as any adherent patches of hotrolled scale, red rust and secondary scale. Because of brush orientation with respect to the rod, a circumferential residual rod marking remains and is very beneficial for lube pick-up.

The resulting rod is descaled, brushed and clean, ready for drawing into wire.
