Feature Wire cleaning

Wire green cleaning focuses on galvanizing

Advertorial on behalf of Decalub

Development of the wire Smooth- Brush (SB) dry cleaning system replaces the most costly operations in wire cleaning process, including acid and other wet chemicals, generating substantial cost savings, environmental benefits and improvement in productivity. For drawn wire cleaning, the SB system features in-line smooth ultra-fine brushing, operating with virtually no speed limitation. The system incor-

porates high density ultra-fine brush bristles that finely impact the wire surface, effectively separating lubricant residue from base material, evacuating dispersed contaminants by moving wire exiting the unit clean of white-metal appearance, providing clean wire that is ideal for galvanising and metallic and plastic coating applications, including Al and Cu clad wire. The system provides an extra-clean product by transversal high-speed ultra-fine brushing all around the wire circumference with automatically controlled brush pressure, adjustable at will, and ensures unchanged wire physical properties with no residual stress induced. In rod cleaning applications, the SB incorporates revolutionary new technology which continuously uses liberated rod scale converted into unique micro-abrading pressure pads, with load adjustable at will, to effectively remove residual solid contaminants from base material, making the product ideal for in-line dry coating/lubrication and direct drawing from mechanically descaled H/C and L/C rod (including 0.90%C). The SB system is recommended for use where the surface finish is of great importance. The system offers consistency and can benefit demanding applications including plating wire, cold-heading wire and H/C wire where the ductility is a prime focus, particularly in production of spring wire, bead wire, PC strand wire, etc. Decalub – France Fax : +33 1 60 20 20 21 Email : info@decalub.com Website : www.decalub.com Flux bath filtration Flux bath in hot-dip galvanising industries must be filtered to improve quality. The iron concentration has to be maintained at a low level to avoid any problem in the treatment. Siebec, with more than 50 years’ experience in the plating industry, has developed a filter system for flux filtration: P51 filter fitted with exclusive high load L-TECH pleated cartridges. This filter system will provide better filtration than a filter press. It can also be installed in series after a filter-press to clean the residual sludge and work continuously with a clean flux bath.
