STRIP SHAPE MEASUREMENT WITH MEASUREMENT ROLL

Shape statistics for the finished coil: 2-D Perspective graph Shape statistics for the finished coil: 3-D graph Vollmer shapemeter rolls follow a BFI patent. The massive roll body is equipped with piezoelectric pressure gauges. The telemetric data transmission and power supply results in an almost maintenance free operation (no slip rings). The diameter, body length and bearing of the shapemeter rolls correspond exactly to those of the deflector rolls. Roll diameters down to 200 mm enable a precise replacement of the deflector rolls in almost all mills. The advantages are obvious: No additional space required for the shapemeters No effects on the strip passline Stack schedule While the strip is pulled over the shapemeter rolls, a variety of discreet measurement zones measures the strip tension distribution. At the same time, the monitor indicates the desired shape for the current strip. If the mill has the suitable control components, the shape is controlled in accordance with the requirements of the end customer (refer to Strip shape control). An important factor for the design of the shapemeter rolls is the selection of the number of measurement zones for the rolls. The more measurement zones, the more precise the detection of the shape profile, but also the more expensive the measurement rolls. Our experts will be glad to give their advice at any time, based on decades of shape measurements on running strip material in mills of all types and on strips of all materials. Roll surfaces: Steel, chrome, plastics or tungsten carbide Shapemeter Roll (BFI) - Leaflet for download (German/English) Planheit_BFI.pdf (544 KB)
