Individual adaptationWith individually manufactured diameters between 200 and 500 mm it is possible to precisely replace the deflector rolls in practically all mills. The outer surface of the roll body is absolutely homogeneous and can be reground on all standard roll grinding machines.
The width of the measuring zones can be freely selected above 17 mm. The number of measuring zones that the roll should have is determined individually.
Vollmer supplies the shapemeter rolls with different surface finishes: Steel, chrome, tungsten carbide or plastic.
The principle - The technology in detailThe BFI measuring rolls use piezoelectric pressure gauges which – spread over the width of the strip – are installed in bores under the roll surface. They measure the strip tension distribution as the strip passes over the shapemeter roll.
Permanently reliableThe telemetric data transmission from the roll – without slip rings – ensures reliable and practically maintenance-free operation. The sensors can be replaced on site. The roll requires neither compressed air nor water.
