Wire cleaning: Direct galvanising, glossy finish for plating quality Advertorial on behalf of Decalub

for complete removal of residual moisture film, providing wire polishing for reflective appearance. The BHW system provides the ultimate combination of simplicity and effectiveness: acid-free, caustic-free, without ultrasonic, without chemicals. Economical and environmentally friendly, the system provides significant energy and process savings in production of clean H/C and L/C wires. The BHW system cleans drawn wire from lubricant residue in applications prior to heat treatment or coating, including galvanising, annealing, patenting, plating, welding (chain, mesh), painting, plastic coating, Al or Cu cladding etc. In a typical application, the 2.6mm (0.102") drawn wire is cleaned in-line at 12m/s (2,400ft/min) with 3 to 5 x BHW units, obtaining a very clean wire, enabling direct galvanising or other metallic or plastic coatings.

The BHW wire cleaning system is used in the most demanding applications, allowing the highest cleaning speed, with all carbon steel wires (including 0.85%C), mechanically descaled or acid cleaned, bare or pre-coated, drawn with calcium or sodium lubricants. The BHW system is particularly recommended for cleaning applications in which a conventional process is inappropriate, especially with wires drawn in severe conditions resulting in increased heat and burnt lubricant tightly bound to the wire surface and embedded in micro cavities. The BHW system incorporates new technology which enables normal plant water to be converted into the most unique “micro-abrading liquid” agent used for cleaning of drawn wire, in-line, at high speed, at virtually zero energy consumption, providing extra-clean wire.

displace/fine scrub/flush cleaning system, benefiting from water immersed high density ultra-fine bristles performing as porous long-life abrading pads that smoothly impact wire surface separating lubricant residue from base material, washing away dispersed contaminants by moving wire, exiting the unit very clean of white-metal appearance.

At exit, the system can be fitted with the PWC (Pressure Wet Cleaning) unit

Basically, it is a sensitive multi-layer
