Prevent corrosion hazards during pickling of precision castings

The following measures can be taken to prevent corrosion hazards during pickling of precision castings:

1. Use acidic metal cleaning agent instead of pickling solution, which not only ensures the cleaning agent effect, but also does not cause damage to the metal material.

2. Strictly control the concentration and temperature of the pickling solution to avoid excessive corrosion of the metal surface.

3. Pre-treat the metal surface before pickling, such as mechanical cleaning, chemical treatment, etc., to improve the corrosion resistance of the metal surface.

4. During the pickling process, pay attention to controlling the pickling time and mechanical stirring intensity to avoid excessive corrosion and mechanical damage on the metal surface.

5. Clean and dry the metal surface after pickling to avoid corrosion of the metal surface caused by residues.
