WIRE rod rust is no longer an alarming
phenomenon, since the introduction of
the Smooth-Brush (SB) wire rod green and
dry cleaning system.
Installed in-line after a simple rod reverse
bending descaler, the SB system removes
excess rod scale and rust, converting
over 95 per cent of rod scale into useful
micro-abrading pads, providing efficiency
and simplicity in rod dry cleaning
applications, H/C and L/C, including
0.98%C.
Continuously liberated rod scale
provides, in-line, an extremely receptive
about 5-micron size texture enabling
powder lubricant to be chemically and
mechanically interlocked to the rod
surface, forming a hard and consistent
anti-wear and anti-friction conversion
coating that is found to perform
comparably to or better than zinc
phosphate.
This achieves in-line direct drawing from
mechanically descaled uncoated bare rod,
at virtually zero energy consumption and
zero maintenance cost, in a totally green
and dry application.
The SB rod cleaning is used in demanding
wire drawing applications, including spring
wire, plating wire, galvanised wire, PC strand
wire, Al clad wire, cold-heading wire, CO 2
welding wire, etc.
The SB dry cleaning system replaces
costly operations in wire rod cleaning
processes (including acid and other
aggressive wet chemicals), generating
substantial cost savings, environmental
benefits and improvement of
productivity.

Special crosshead for
special products
Low-smoke zero-halogen material is
commonly used for a wide range of
products, such as low-voltage power
cables, automotive cables and premises
cables. This material is special with
regard to its properties, since it only
allows for low-temperature processing.
Extrusion crossheads typically run at high
temperatures and high pressure, which is
why a special solution is required for the
LSOH material.
Rosendahl’s RX 40 F.1.0 extrusion crosshead
is designed to run high output at low
pressure to ensure safe and adequate
handling of highly filled materials. The
precise match of the crosshead and its
tools allow for low shear rates and stable
processing at lowmass temperatures.
The RX 40 F.1.0 is a single-layer extrusion
crosshead that is easy to both assemble
and disassemble. Maintenance is also
kept very simple and easy. It is very user
friendly and most importantly it meets the
material’s special requirements to achieve
best results on the final product.
