Steel plate inspection is a multi-link, multi-faceted process designed to ensure the quality, performance and safety of steel plates. The following are the main steps and aspects of steel plate inspection:

Preparation work:

Confirm the specifications of the steel plate.

Ensure that the surface of the steel plate is clean and free of impurities such as oil, gravel and dust.

Maintain a suitable ambient temperature to avoid too high or too low temperature affecting the test results.

Appearance inspection:

Check whether the surface of the steel plate is smooth, without concave, convex, pocked and other defects.

Check the surface of the steel plate for scratches, cracks, cutting edges, etc.

Check the surface of the steel plate for bubbles, inclusions, blisters, spots and other defects.

Check whether the surface of the steel plate is coated, painted, anti-rust layer and other surface materials.

Size detection:

By measuring the length, width, thickness and other dimensions of the steel plate, determine whether the size of the steel plate meets the requirements. Use a ruler, protractor and other tools for measurement to ensure the accuracy of the steel plate size.

Chemical composition test:

The content of elements contained in the steel plate is determined by sampling experiments. Use chemical analysis methods, such as spectral analysis, wet analysis, etc., to detect the content of various chemical elements in the steel plate to ensure that the steel plate meets the chemical composition requirements of a specific grade.

Mechanical properties test:

Including strength, extensibility, impact toughness and other parameters of the test. The tensile test and impact test are used to evaluate whether the mechanical properties of steel plate meet the standard requirements. These tests can determine the steel plate's maximum load bearing capacity, impact resistance and other important characteristics.

Defect detection:

Non-destructive testing methods such as X-ray testing, ultrasonic testing, magnetic particle testing, etc. are used to find cracks, pores, slag inclusion and other defects in steel plates. These methods help identify problems early and fix them.

Records and reports:

Record all test results in detail and write test report. This helps to track the quality of the steel plate and provide supporting documentation when required.

The inspection of steel plates is a rigorous process that requires professional equipment and personnel to perform. Through this series of tests, we can ensure the safe and stable use of steel plates in engineering projects. At the same time, the strict implementation of steel plate testing standards is crucial to ensure engineering quality, and is of great significance for improving the quality of steel plate products and promoting industrial development.
