Roll eddy current automatic flaw detection system
produce
The COBE roll eddy current detector is a high-precision flaw detection instrument that detects the change in coil impedance in real time through corresponding detection methods. During the roll detection, the roll surface and the coil move relative to each other, and the change in the hardness of the roll surface (soft spot) And surface cracks lead to changes in electrical conductivity, which causes changes in eddy current density. Changes in eddy current density cause a rapid change in coil impedance and display this change on the display.
The COBE eddy current detection system is a professional flaw detection system developed by our company. It is the leading product in this type of equipment. Its detection sensitivity is higher, and it is easier to find small cracks on the roll surface and its performance is stable and reliable. The spare parts of the equipment are highly interchangeable, all parts can be directly replaced, and maintenance and maintenance are convenient.
Features
Simultaneous detection of flaws such as cracks, hardness changes and residual magnetism on the roll surface.
It can be tested according to two modes of grinding and grinding and flaw detection after grinding
According to the need to choose automatic demagnetization or manual demagnetization
The equipment can automatically adapt to different roll speeds
With the function of generating circumferential / axial partition coordinates, making the defect location more intuitive
Probe automatic and emergency reset function, under fault conditions, the probe can be immediately reset to a safe state
Inspection and management function of flaw detection history.
