In-line mechanical descaling
The Lämneå in-line rod cleaning system is intended for the continuous, in-line
descaling, of wire rod. The system consists of a 4- or 6-sheave scale breaker
and a 4-pair brushing unit.
In operation, the rod is pulled through the scale breaker by the wire drawing
machine. On rod properly made for mechanical descaling, 80%-90% of the
loose scale falls from the rod and collects in the scale breaker cabinet.
The remaining 10%-20% is loose,
but clinging to the rod due to electro-
static charge; the brushing machine
removes the scale residue. The
resulting rod is production clean wire
rod, ready to be drawn.
Special features of the Lämneå
system include an adjustable scale
effect, self-adjusting brushes and
a low cost, environmentally friendly
operation that needs no water.
