Working principle and application of air bearing shape meter

Shape meter is the important unit in the flatness control system.Its accuracy can affect flatness of rolling products at the working line.The working principle of air bearing shape meter and signal processing method of the 1550 four-high irreversible single cold foil rolling mill have been investigated.The flatness measuring value has been obtained by interpolation value,electrical signal smooth processing and the calculated flatness value received from the relationship of radial direction load on measuring roll and shape meter.The air bearing shape meter is being used with excellent result at the worksite now.
