Modular measurement gauges for hot rolling mills

Depending on the maximum product dimensions the three new models cover measuring fields up to 200, 400 or 800mm. The Profilemaster ® delivers accurate and stable readings, and a high reliability is guaranteed thanks to a sophisticated, multi-stage protection and purging/cooling system. Key advantages include: up to eight cameras; modular camera setting – any shape can be captured; up to 16,000 points/ contour (2,048/camera) = 5,734,400 points/second (with eight cameras); high sampling rate of 350-500/second (full profiles/second); four different colours of laser in an eight camera system means no interference; shape fault detection (SFD); compilation of a 3D model thanks to high sampling rates; and trouble-free maintenance Haeusler, which frequently relies on Austria-based Linsinger’s expertise. In addition to the Linsinger KSS sawing machines for steel billets and the Linsinger KSA saws for seamless tubes, the Linsinger BFMK strip edge millers and the Linsinger MC multi- cut parting saws have been used successfully in longitudinally welded pipe mills for decades. The specialised portfolio for large diameter pipe mills is complemented by the Linsinger PFM plate edge milling machine and the Linsinger RFM pipe end bevelling machine. The Linsinger PFM plate edge milling machine is used for preparation of welding edge profiles. The machine works with height copy milling units and is capable of maximum cutting efficiency combined with minimum consumable tooling costs. Simultaneous milling of both longitu- dinal sides saves time and money. The profile milling tools made by Linsinger

ZUMBACH Electronic has introduced three new additions to its line of profile gauges for steel and metal profiles. The gauges are based on the laser light section technique and by camera vision, often also called the “light cut” principle. Up to eight line lasers “mark” the contour of the product, and the respective cameras each capture a large number of pixels on the product contour. Sophisticated software then adds four pictures to the true, orthogonal section of the profile. All critical dimensions, angles and radii can be programmed together with their tolerances. Operators and supervisors can not only monitor the true profile as a 1:1 section online, but also see irregular faults such as seams, concave or convex shapes. All standard profiles such as H, I, U and L beams, hexagons, squares, flats and any special shape are measurable. LINSINGER’S technology leadership, expert knowledge and customer service aim to provide large pipe manufacturers with production security. “Linsinger has continuously optimised and improved machine performance and this has been backed up by high levels of R&D investment and a balanced in-house sourcing policy,” said Linsinger CEO Hans Knoll. For more than 70 years Linsinger’s in- house expertise, strict quality standards and deadline reliability have been valued by the large-tube industry. Producers of large diameter pipe require customised solutions – whether for pipe cutting, for longitudinal seam preparation or for pipe-end chamfering – not only with high precision, but also with ambitious production capacities and low running costs. Currently, the manufacturing of a plate milling machine PFM 90/600LL and a pipe end bevelling machine RFM 56/12000 is being completed for

enable virtually any geometry to be milled with high precision and speed. The Linsinger RFM pipe end bevelling machine enables simultaneous cham- fering of both pipe ends by a single operator. The chamfered pipe surpasses API specifications and the long tool life ensures lowest possible running cost. The movable milling units chamfer a range of pipe lengths and the internal copy tools guarantee consistent chamfer geometries. The Linsinger RFM pipe end bevelling machine chamfers diameters between 16" and 90" with practically no burr. The backlash-free Linsinger patented DPD double power drive transmission system uses twin motors, small flanges and high torque for absolute precision.
