Measurement gauges for hot rolling mills ZUMBACH Electronics 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 “light cut” principle.

can not only monitor the true profile as a 1:1 section online, but also see irregular faults such as seams, and concave or convex shapes. All standard profiles such as H, I, U and L beams, hexagons, squares, flats and any special shape are measurable. 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 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 the lasers 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 with quick and easy access to the maintenance points.

In other words they pay a small initial sum and then they open a leasing on the longest possible period. In this way, however, we producers are obliged to operate with very scarce liquid assets and it is very difficult to obtain funding. Investing in innovation then becomes more complicated. Nevertheless, it is the only solution since a machine with a design dating back to five years ago is not demanded by the market,” he added. Mr Ribolzi added that: “Technology in coil machining is already very advanced and inventing something new will be difficult. To grow, paradoxically, it will be necessary to “resize” the offer. In other words the market is saturated and there will be a natural selection that will leave room only for the best enterprises. In the meantime, we must resist and look for new commercial outlet areas. “Today it is difficult to acquire orders at interesting prices even in rising countries like China. We have to search elsewhere, where industry is developing and entrepreneurs are going to invest.”

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.

Improving quality while decreasing price EUROSLITTER Srl designs and manu- factures slitting lines, coil packaging lines, cut-to-length lines, flatteners and rotary shears intended for processing strips and coils of alumin- ium, steel, stainless steel and other metals. Recently the requests for machines for big-thickness coils have been increasing, but the market is getting saturated for this plant typology, too. On the other hand, all manufacturers are trying to go where the demand is more pressing.”

In general, however, today the market asks for machines featuring better quality and precision at increasingly lower prices, which is impossible. “To reduce prices we have tried to simplify the structure of our machines, eliminating unnecessary frills, but it is only a dream, we have just reduced margins. On one hand, this represents a compelling and exciting challenge;

The owner of the company, Ezio Rinaldo Ribolzi, said: “We offer slitting lines for thicknesses ranging from 0.1 to 6mm that work at high speed and are sturdy and able to aid users in reducing idle times. Currently, the demand for standard products is virtually zero: today the market requires customised machines, often designed from scratch.

on the other hand, such decreases com- promise our efforts and the innovative content of our products. Sometimes, we are compelled to conform to that trend to avoid losing customers,” added Mr Ribolzi. “Quality, efficiency and productivity are taken for granted. Today customers’
