After large steel castings are produced, they need to be inspected. Inspection is to ensure the reliability and long life of steel castings in harsh working environments and meet the industry's requirements for use under high temperature, high pressure and corrosive conditions. Let's take a look at the steps for finished steel casting inspection of Tenfaye.
1. Check the size and weight of steel castings to ensure that they meet the requirements of drawings and technical specifications.
2. After casting, steel castings need to be surface treated, excess risers and flash are removed, and the surface is polished to make it smooth. This step is to reduce surface defects of steel castings, such as cracks, sand holes, etc.
3. Large steel castings undergo heat treatment processes, such as annealing, normalizing or tempering, in order to optimize their metallographic structure, improve mechanical properties and deformation resistance.
4. Perform non-destructive testing such as ultrasonic testing and magnetic particle testing to check whether steel castings have defects such as bubbles, cold shuts, and non-metallic inclusions.
5. In order to enhance the corrosion resistance and service life of steel castings, protective coatings are usually applied to their inner and outer surfaces.
6. Conduct mechanical property tests on steel castings, including hardness tests, impact tests, etc. to verify their strength, toughness and impact resistance.
7. Comprehensive quality inspection of large steel castings is also required, such as X-ray inspection, to confirm requirements and quality standards.
