IMPOC
IMPOC Online strength measurement
The IMPOC measuring system is a testing device for automatic, non-destructive online determination of mechanical parameters (tensile strength, yield point) of ferromagnetic steel strip.
The functioning of the non-contact measuring system is based on periodically magnetising the strip, followed by measurement of the gradient of the magnetic residual field intensity on the upper and lower side of the strip.
The mechanical parameters of the steel strip are determined using regression relations, portrayed online in the form of a graph on a plotting computer in the control station and recorded. If a limiting value of the mechanical parameters is exceeded, a warning signal including information on the strip areas concerned is automatically triggered.
Using the IMPOC measuring system, the mechanical parameters of each steel coil produced are continuously documented on the basis of strip length and strip width.
