The adjustment of the eddy current flaw detector before on-line eddy current flaw detection is necessary. To prepare for the start-up of the eddy current flaw detector, select the appropriate probe diameter and the corresponding size guide sleeve for the diameter of the wire to be tested.
Online flaw detection is not only more technically demanding than offline flaw detection, but also more difficult. It must not only ensure the normal operation of the eddy current flaw detector itself, but also match the dynamic and static conditions of the production line.
For example: the straightener fixed in front of the probe of the eddy current testing equipment is used for straightening the steel wire and for positioning. If the straightening is too tight, although the effect is better, the resistance is increased, which brings the normal operation of the steel wire in the heat treatment line. To have a certain impact.
Loose straightening will increase the vibration of the steel wire and affect its concentricity.
The I/O electrical control part of the eddy current flaw detector is also closely connected with the production line. If the heater of the heat treatment line is not turned on, the eddy current flaw detector cannot work normally.
