?The screw is widely used in all large machinery and equipment, and it is closely related to the performance of the mechanical equipment. If the screw is suddenly damaged during the use of the screw, it may seriously damage the equipment and cause the equipment to be unable to operate normally. Therefore, in the process of using the screws, we should make the best maintenance and maintenance so as to be more safe. Use.
There are six major problems to be noted when using screws.
1. The process of rinsing with screws is very important. It needs to be very careful and careful. There will be residues left on the surface of screws. Rinse this step after cleaning the silicate cleaner.
2. During the heating process of the screw, the stacking should be combined, otherwise it will cause slight oxidation in quenching oil.
3, there will be phosphide white residues on the surface of high-strength screws, indicating (first points) that the operation is not careful enough.
4, the surface of parts will have black phenomenon to produce chemical reverse use, indicating that the work of heat treatment do not do well thoroughly, the surface of the alkaline residue is not completely removed.
5. Parts of standard parts will rust in rinsing, and rinse water should be replaced frequently.
6, excessive rust phenomenon shows that the use of quenching oil is too long, and new oil or replacement is needed.
