LLM – multi-pass cold rolling lines

Teurema’s LLM cold rolling line m m

reach the multi-pass and, by means of the pulling force of the capstans, will be reduced and/or ribbed. The wire is collected by the spooler or coiler, to a maximum coil weight of 3,000kg.

LLM multi-pass rolling lines work with an inlet wire rod diameter of 5.5mm to 8mm; the wire is reduced to between 0.8mm to 6mm. The horizontal or vertical capstans have plasma or ceramic hardened surfaces. Wire rod, from the coil positioned on the tilting fingers, will pass through the vertical static payoff, the mechanical de-scaler and the lubrication unit, then

LLM from Teurema is a rolling line for smooth or ribbed wires in high, medium and low carbon steel. In the case of construction wire, either three or four passes are carried out using Eurolls’ cassettes type A or B. For small diameter wires, or special products, the line uses more passes and Eurolls’ microcassettes. The sturdy modular structure is said to make it simple to adapt the number of passes to the needs of the process. EDM wires – topas ® plus D The topas ® plus D EDM wire from bedra has been developed for all machines which require straightened wire for automatic threading. The high tensile strength of 800 N/mm² allows automatic thread- ing and resists wire breakage; both important factors for unmanned overnight operation. Its resistance to breakage and its high thermal and electrical capacity ensure process stability, thus making this electrode suitable for speed cutting as well as for contour precision cutting. As with the other electrodes of the topas ® plus family, topas ® plus D allows a better exploitation of the performance potential of modern generators. A significant increase in performance can be achieved, even under unfavourable flushing conditions, and processing times can be considerably reduced.

Ecocontrol, display and report

Ecocontrol 600 from Sikora is the smallest of the company’s processor systems, especially adapted to individual line conditions for highest productivity within wire and cable production. Ecocontrol 600 offers one serial interface for the connection of a Sikora measuring device such as Laser 2000, Centerview 8000, CV-Intube 6000 or LED 8025 XY. Digital contacts also allow readings from the lump and neckdown detection system, Lump 2000 and spark tester, Spark 2000. There are graphical length-related trend diagrams for all values combined with a graph of the distribution of the single values (statistical distribution curve) and a statistic with the minimum, maximum value, the mean, standard deviation, Cp and Cpk values. The operation is menu-driven via a touch screen. Sikora combines the Ecocontrol 600 with a Laser 2000 for the measurement of the hot or cold diameter in two or three measuring planes, or the Centerview 8000 for an 8-point-eccentricity, 4-axis diameter, and 8-point ovality measurement. Where stringent quality control is required, Ecocontrol 600 can be used with the CV-Intube 6000, for diameter measurement within CV-lines, or the LED 8025 XY, a diameter-measuring device capable of accurately measuring the eccentricity of transparent products.

Data can be transferred to a line PC via an Ethernet-interface or an USB flash drive, while a printer provides a hard copy of the production quality.

Sikora offers Ecocontrol 600 configured in several languages.
