Non-contact measurement

Zumbach’s new laser diameter measuring head has been designed especially for wire drawing or similar applications. An integrated CPU (central processing unit) allows for communication with a host computer or the special USYS Multiline processor from Zumbach. The integrated processor allows the raw measuring data to be filtered and provides SPC reporting capability of a selection of parameters and many further functions. Compact and sealed to IP 65, the Odac® 14XY-WD can be easily integrated or retrofitted. For compact drawing and spooling machines the measuring head will typically be mounted onto the machine block, between the drawing and spooling area, if possible between two guiding rollers. For separate drawing and spooling machines, the measuring head can be mounted on a support and measure the wire diameter between the two machine blocks.

Features of the system include:

• •

Economy Dual axis Accuracy

• Highly immune to dirt – long standing time between cleanings • Output for local displays • Line speed input • Zumbach Electronic AG – Switzerland Fax : +41 32 356 0430 Email : sales@zumbach.ch

Cleaning and preparation for frictionless drawing Advertorial on behalf of Decalub

controlled and a powerful multi-function LVC/PDH ultra-high pressure coating system, installed in the first draft, permits in- line high-performance dry coating, plasticising and lubrication of the bare rod. Liquefied standard dry lubricants, the viscosity of which is automatically controlled during the

drawing operation, completely eliminate traditional wet pre-coating chemicals including phosphate and borax pre-coatings. Typical application of the DCCD process is in direct drawing from 5.5mm diameter mechanically descaled bare rod, with 0.83/0.88% carbon content, without pre-coating wet chemicals, with an out- put of 2.2tph and with a die life of 200 tons per die in the first draft. Lubricant film achieves frictionless drawing by physical separation of wire-die contact in all drafts, eliminating friction heat, enabling die wear of 0.1-0.3 micron per ton of wire drawn, with no speed limitation, dependent mainly on rod payoff and wire take-up modes.

Rod cleaning and wire drawing by DCCD process ▲ ▲

The latest version of DCCD (Dry Cleaning, Coating and Drawing), incorporating the New-Coat coating, eliminates the most costly parameters in wire drawing operations, including elimination of acid and traditional wet pre-coating chemicals. The process is said to offer significant downstream benefits enabling users to target a total saving of 50% to 65% in production costs. The DCCD process allows immediate substantial cost savings in the most demanding drawing applications including spring wire, high-tensile rope wire, bead wire, PC strand wire, AL cladded wire, plating wire, bright wire and CO 2 welding wire. Scale cracking by rod reverse bending is followed by ultra-fine brush clean- ing. Brush pressure is automatically
