How to maintain the screw plug?

How to maintain screw plugs by manufacturers of screw plugs:

1. When rinsing the screw plug, because this process is very critical, it needs to be very careful, and there will be residues left on the surface of the screw plug during this process. The process of rinsing is after cleaning with silicate cleaning agents.

2. The deposition of the screw plug must be combined during the tempering and heating process, otherwise it will cause slight oxidation in the quenching oil.

3. The surface of the high-strength screw plug will appear phosphide milky white residue, indicating that the inspection is not careful and careful during operation.

4. If it is found that the surface of the parts is blackened and causes chemical reaction, it means that the work during the heat treatment is not very good and complete, and the alkaline residue on the surface is not completely removed.

5. The standard parts will be rusted during rinsing, and the commonly used water for rinsing should be replaced frequently.

6. Excessive rust conditions indicate that cooking oil for quenching oil has been used for a long time and needs to be added to new oil or replaced.
