Advantages and disadvantages of ultrasonic flaw detection for slag pots

With the development of the times, industrial production is also developing in a larger scale. The scale of cast steel parts is larger, the shape is more complex, and the quality requirements are higher. The internal defects of the anode steel claws of large cast steel parts are invisible to the eyes. At this time, it is necessary to use some testing equipment. Non-destructive testing is often used for internal quality. Non-destructive testing has the advantages of no damage to the quality of castings, large-scale testing and accurate positioning of defects, and is widely used in the identification of steel casting quality. Ultrasonic flaw detection is a test to check the inspected parts and internal quality without damaging the steel castings or original materials.

Advantages of ultrasonic flaw detection:

1, Strong penetration ability, high sensitivity;

2, Can be found with a diameter of about a few millimeters of air gap reflection can be appropriate reflector; The size of the detectable defect can generally be considered as 1/2 of the wavelength.

3, It is more accurate in determining the orientation, size, shape and other aspects of the internal reflector;

4. Only approach the inspected object from one side;

5, Can immediately supply defects inspection results;

6, Safe operation, simple equipment.

Ultrasonic flaw detection anode steel claw shortcomings

1. It should be operated carefully by experienced personnel;

2. It is difficult to view rough, irregular, small, thin or heterogeneous data;

3. It is still difficult to make a very precise qualitative and quantitative characterization of the found shortcomings;

4, Not suitable for the cavity structure;

5, Unless photography, generally leave little retrospective data.

Knowing the advantages and disadvantages of ultrasonic flaw detection, you can determine whether it is appropriate to use ultrasonic flaw detection according to the structure of the casting. Proper flaw detection method can ensure the quality of the product.
