New all round device for resistance measurement from Burster

Resistance measurement and Resistomat® are terms that belong together.

Burster has launched a new Resistomat® 2316 – a tough, universal and compact resistance measurement device that suits all applications in industry surroundings as well as in laboratory conditions. The new measurement device combines precision as well as easy handling and system integration capability quite perfectly. The instrument measures resistances in the range of 2,0000 mΩ up to 200,00 kΩ with an accuracy of 0.03 % rdg, with the resolution in the smallest range reaching 0.1 μΩ. A specially developed measurement input protection allows the measurement of inductive samples like electric motors and transformers as much as coils with iron cores. The measurement of heating elements, fuses, switch and relay contacts or cables and wires are just a few further application fields. Autorange, temperature compensation of the test sample, cable fraction detection and thermovoltage compensation are self-evident.

For the integration into fully automatic test stations the instrument features a PLC and RS232/USB interface. Thanks to the large and backlit LCD display, the measuring value can be easily read from a major distance in dim production halls, as well as in direct sunlight. The simply designed choice of the different measuring parameters is affected via an elaborate operation menu that provides five languages – English, French, Spanish, Italian and German. Burster GmbH & Co KG – Germany Tenova’s new slab furnace in operation After the successful completion of the erection and start up phase – jointly carried out by Tenova LOI Italimpianti, Techint and Ternium Hylsa – the new slab reheating furnace at the Ternium steel plant in Monterrey, Hylsa, Mexico, has been put into operation. The new furnace features the latest- generation technology using the new FlexyTech® Tenova flameless burners that combines reduced consumption and extremely low emissions with a reheating quality at today's highest levels. These burners have already been successfully installed by Tenova LOI Italimpianti on recent high capacity reheating furnaces. The new furnace will replace the old battery of pit furnaces, currently in the dismantling phase, guaranteeing an increase in production capacity. The contract for engineering work and supply of the advanced technology plant components was awarded to former Techint Technologies Furnace Business Unit based in Genoa (Italy), now Tenova LOI Italimpianti, which completed the project on schedule. The contract covered support for plant installation, testing, start-up, and related services.

Rod dry preparation enables high-speed l frictionless drawing

Decalub, France, has introduced the new generation DCCD (dry cleaning, coating and drawing) process which eliminates the most costly parameters in the wire drawing process, including elimination of acid and pre-coating chemicals. As a consequence, the new process offers significant downstream benefits enabling the users to target a total saving of 50- 65% in production costs of drawn wire. The system 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, CO 2 welding wire, etc. Following the scale cracking by rod reverse bending and rod smooth brush cleaning, upon automatically controlled brush pressure, the powerful multi- function LVC/PDH system, installed in the first draft, permits in-line high- performance dry coating and lubrication of H/C or L/C mechanically descaled bare rod, with liquefied standard dry lubricants the viscosity of which is automatically controlled during the drawing operation,

completely eliminating traditional wet pre-coating chemicals. One of the typical applications of the DCCD process consists in direct drawing from 5.5mm diameter mechanically descaled bare rod, with 0.83/0.88% carbon content, without pre-coating, with an output of 2.2 tons per hour and with a die life of 200 tons per die in the first draft. Full lubricant film achieves frictionless drawing by physical separation of wire-die contact in all drafts, enabling diewear of 0.30 micron per ton of wire drawn, with virtually no speed limitation, dependent mainly on rod pay-off andwire take-upmodes.
