Combined Eddy current testing and Ultrasonic testing system
This is the combined testing system (ET+UT) ,as a new testing method based on the electromagnetic and ultrasonic theory, is the breakthrough of COBE teams after years of industrial and laboratory studies.
This model is designed particularly for on-line testing applications. However,the size and nature of flaws detected depends on the condition of the material and environments.The spare parts of the equipment are highly interchangeable, all the parts can be replaced directly, and the maintenance is convenient. Can be based on the detection results and then guide the operator to more accurate grinding.
Testing material:Cr2,Cr3,Cr5 ,Alloy forged steel, high speed steel, cast steel, etc.
Testing requirement: Ultrasonic testing for inside cracks , composite layer porosity and thickness testing ; Eddy current testing for surface and sub-surface cracks and oft spots testing
Roll diameter : 500-1400mm
Testing model: ET+UT testing
1. Detection coverage : 100% body area of the roll
