Wire lubrication and cleaning
The GPS/PDH wire re-coating system greatly improves the present state of both
wire lubrication and in-line wire cleaning. The system enables high-speed smooth
frictionless drawing, benefitting from the wire dry re-coating in intermediate drafts
with completely water-soluble sodium lubricants.
Full film consistent coatings are achieved in a wide variety of selections from ultra
thin coat for plating wire through a strongly adherent hard coat for high-tensile
spring wire with no speed limitation.
The GPS/PDH system is said to allow immediate substantial cost savings in
drawing applications, including spring or plating wire, completely eliminating
traditional wet pre-coating chemicals, such as phosphate or borax, for all direct
drawing applications from rod. The system allows in-line wire cleaning in a wet
application in last draft, operating with a specific paste in a continuous “IN” and
“OUT” motion, in closed circuit pressure lubrication self-generated by the unit,
performing wire cleaning and polishing to a reflective wire appearance, at high
speed, in a single run. The system operates at zero energy consumption and
zero lubricant consumption and waste. It can be easily installed into the existing
soap-box, and operational within 10 minutes.

Wire descaling
Wire Lab Company manufactures a comprehensive line of mechanical descaling
machinery for steel wire producers. A wide variety of models allows customers
to put in place the Wilco mechanical descaling system which most closely
matches their wire drawing requirements, with consideration given for machinery
investment, maintenance cost, cost of any consumable items and overall quality
requirement of the finished wire product. Simple to use, basic mechanical
descaling systems (model 920 air jet and model 1030 water jet descalers) are
well suited for producers of industrial quality wire products where emphasis is on
maintaining the lowest possible overall production cost.
More feature-rich Wilco descaling systems allow customers to use wire rods
of various qualities with the objective of producing a consistently cleaned wire
rod suitable for making into higher quality wire products. These systems (model
1250 and model 1750 automatic wire
brush descalers) incorporate the Wilco
automatic rod brushing machine into the
process. Eight circular wire brushes are
positioned around the rod circumference
to aggressively clean the rod surface of
secondary scale and red rust, both of
which are detrimental to producing high
quality wire products.
More specialised Wilco descaling
systems (model 1060 descaling system
with lubricant pre-coating and model
LRD scale breaker for large diameter
rods) satisfy the needs of more
specialised producers. The model 1060, as part of the mechanical descaling
process, applies lubricant pre-coating compound in the final stage of the
mechanical descaling process.
Manufacturers of high carbon wire and those working with very high finishing
speeds may benefit from the increased lubrication established by the pre-coating
compound. The Wilco large rod scale breaker (model LRD) is designed for
processing larger diameter rods, up to 19mm in diameter. Sheave offset is
controlled by hydraulics, thereby allowing simple straight through string-up of the
scale breaker.

Coral unit for the
recovery of copper
and sulphuric acid
The process of coppering steel wires,
coils and tubes produces waste
containing copper sulphate, iron
and sulphuric acid. Using the Coral
electrodyalisis unit from Condoroil, this
waste can be processed and divided
into by-products such as sulphuric
acid and metallic copper.
The sulphuric acid can be re-used in the
copperising solution, while the metallic
copper can be sold with electrolytic
grade. Furthermore the recovery of the
by-products allows a reduction in the
cost of waste treatment considering
the reduced consumption of lime, the
reduced production of waste sludge to
dispose and the reduced concentration
of copper hydroxide.
The unit is compact and modular,
ready to be upgraded in case of
increased production.
