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.

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.

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.

The unit is compact and modular, ready to be upgraded in case of increased production. Condoroil Impianti Srl – Italy Fax : +39 0332 945303 Condoroil’s Coral unit reduces the ❍ ❍ cost of waste disposal
