Anchor Bolt is a casting used on the railway, generally made of cast steel.
For this type of casting, in addition to strict technical index testing, the
material of the equipment should be processed. The castings such as anchor bolts
provided by Railway Fastening System Supplier have been used in the field
environment for a long time, and are eroded by the humid environment. If the
maintenance work of castings such as anchor bolts is not done well, it will lead
to corrosion of castings. See how Anchor Bolt and other castings should prevent
Surface treatment method:
1. Surface cleaning: Cleaning must select the appropriate method according to the nature of the surface of the anti-rust object and the conditions at that time. Commonly used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
2. After the surface is dried and cleaned, it can be blown dry with filtered dry compressed air, or dried with a dryer at 120-170 ℃, or wiped dry with clean gauze.
Method of applying anti-rust oil:
1. Immersion method: Some small items are immersed in anti-rust grease to allow a layer of anti-rust grease to adhere to the surface. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease.
2. The brushing method is used for outdoor construction equipment or products with special shapes that are not suitable for immersion or spraying. When brushing, it is necessary to pay attention not to build up, but also to prevent missing coating.
3. Spraying method Some large rust-proof materials can not be oiled by the immersion method. Generally, filtered compressed air with a pressure of about 0.7Mpa is sprayed in a clean air place. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but must adopt perfect fire prevention and labor protection measures.
The above is the rust prevention work for anchor bolts and other castings that we share, so that even if the equipment is well protected in later use, it can reduce the occurrence of casting rust. The anchor bolts provided by our company are reliable in quality. Whether it is the corrosion or quality of the cable, these methods can alleviate them.
