In modern industrial manufacturing, eddy current testing technology has become an important tool for ensuring the surface quality of forged steel rolls. Eddy current roll surface detection is based on...
The two-piston rollers rotate in the same direction to drive the upper piston rod to rotate, and then the pushrod pushes the piston rod through the probe to complete the detection.
First, the piston rod status and parameters
1. The piston rod specification is φ10-φ28 and the length is 100-500.
2. Piston rod material: ordinary carbon steel, alloy round steel.
3. Piston rod state: roughness Ra0.1, roundness 0.02, round beat 0.07
4. Inspection speed: Take the workpiece diameter 20, length 450, detection distance 300 as an example, detection rhythm 6 seconds.
5. Detection site: the part with the largest outer diameter.
6, detection accuracy: for 0.1mm (depth) x0.1mm (width) x3mm (length) crack
7. The rotation speed of the workpiece: According to the detection speed, the piston rod rotates for one week, and the propulsion distance is 3-5 mm.
