INTERNATIONALLY RECOGNISED AS LEADERS IN GALVANISED WIRE TECHNOLOGY
AND ENVIRONMENTAL IMPROVEMENT IN WIRE MANUFACTURING.
The steel and wire industry is increasingly facing challenges
due to the ever changing regulations being forced on the
industry by global warming and other environmental issues.
The recent United Nations Conference held in Paris in 2015
reached an agreement whereby participating countries would
limit the rise in global temperatures to less than 2°C. The
focus is on reducing CO₂ emissions.
In addition the industry faces more challenges in the waste
pollution to the environment from the use of chemicals
throughout the making of wire.
Since the late 1990s our company has worked with wire-
mills to help achieve the minimisation and elimination of
chemicals and other environmental issues.
Many of the changes included:
• Removal of acid cleaning for rod.
• No use of in line wet lubricant coating systems.
• Recycling of any chemicals in wire drawing.
• No use of acid and flux in galvanising.
• Energy reduction programs through more efficient
operating systems and technology uses.
High speed galvanising lines of DV200+ with Zinc, ZnAl5%,
ZnAl10% single dip technology. No need to use acids or flux
and also with reduced energy consumption.
High efficiency, high and low temperature furnaces for low to
high carbon wires.
Electromagnetic Wiping (EMW®) for medium and heavy
coating weight wires. Customer coating weights range from
150g/m² to over 600g/m², with over 65 systems now sold
worldwide. Accurate, even coating for round and shaped wires.
Lubricant conditioning (LCM) for wire drawing. This technology
allows companies to maximise the wire drawing machine
speeds by providing a conditioned lubricant well suited for
the needs of drawing dies. Traditionally companies had to
either dispose of used but good lubricant or just keep topping
up the soap box which affects die life and potentially the
drawn wire properties. Now there is no need to throw away
good lubricant which costs money and has an impact on the
environment. Many of the machines are located in well-known
wire producers. Depending on wire drawing practices we have
been able to condition between 45% and 95% of the used
lubricant. With our ability to control the granulation makeup
of the lubricant we are able to provide for excellent die box
performance.
Improved lubrication of wire through the use of RSD
technology which enables continuous improved lubrication
of the wire allowing for better die life and increased machine
speeds.
Our people’s know how and experience has through consulting
services enabled companies worldwide to save over USD30M
by purely improving their existing technology and helping them
to do things they were not able to do in the past.
