The BH-S is a green, dry cleaning process of great potential used in-line in the most demanding applications, allowing the highest cleaning speed with all steel wires and rods (including 0.90%C), mechanically descaled or acid cleaned, bare or pre-coated, drawn with calcium and sodium lubricants. rod cleaning (rust and scale removal) prior to drawing and wire cleaning from solid lubricant residue, or other contaminants, prior to metallic coating, heat treatment, etc. Development of the BH-S rod and wire dry cleaning system provides the ultimate combination of simplicity and effectiveness, replacing the most costly operations in the wire cleaning process, including replacement of acid, ultrasonic and other wet chemicals, generating substantial cost savings, environmental benefits and improvement in productivity of clean H/C and L/C wires. particularly recommended for cleaning applications in which a conventional process is inappropriate, especially with wires drawn upon severe conditions resulting in increased heat and burned lubricant Applications include wire The BH-S system is CONTRÔLE has developed a special version of its eddy current rotating head, RotoETscan HV, suitable for line drawing inspection for a diameter range of 0.8 to 10mm. This system, which is easy to install on the production line, integrates a turntable (cassette) adapted to the product diameter. Eddy current probes (two or four) installed inside the cassette rotate at high speed (18,000rpm) around the wire, while the product translates into the rotating head. The nozzles inside the system ensure proper centring of the wire during inspection. Connected to the EC instrument Zet@ Master, it detects longitudinal defects >50μm on the product, but can also be combined with other CMS equipment, such as magnetising or demagnetising units, for a complete product inspection.

tightly bound to the wire surface and embedded in micro-cavities. Basically, the BH-S is a smooth and sensitive multi-layer micro-shaving/ abrading that finely impacts rod or wire surface separating scale, rust or lubricant residue from base material, evacuating away dispersed contaminants by moving wire rod, exiting the unit extra clean of white-metal appearance at extreme speed, operating at virtually zero energy consumption. The BH-S units can be used in all positions – horizontal, vertical or inclined. Decalub – France Email : info@decalub.com Website : www.decalub.com
