What are the reasons for the corrosion of the crane chain?

After the crane chain has been used for a period of time, it is found that there is a rust phenomenon, which may even affect the normal lifting belt operation when it is severe. How does this rust phenomenon occur? Next, the editor of Yuantai Crane will introduce the factors that cause the rust of the crane chain:

1. The company did not strictly follow the clean and anti-rust regulations and oil seal anti-rust packaging requirements during the production of the lifting chain to prevent rusting of the lifting chain parts during the processing and the lifting chain products after installation. If the lifting chain touches corrosive liquid or gas, etc.
2. The quality of the anti-rust lubricating oil and clean kerosene used by the company in production cannot meet the requirements of the technological rules.
3. As the quotation of crane chain steel fell again and again, the raw materials of the crane chain steel gradually declined. For example, the content of non-metallic impurities in the steel is too high (the increase of the sulfur content in the steel reduces the anti-corrosion function of the material itself), the deviation of the metallographic arrangement, etc. The chain steel used by the current production company is more of a mixed bag than the amount of miscellaneous steel raw materials.
4. Some companies have poor environmental conditions and the air contains high levels of harmful substances, and the turnover space is too small to carry out useful anti-rust treatment. Coupled with the hot weather, there are also scenes of production workers violating anti-rust regulations.
The above is the reason for the problem of rusting of the crane chain organized by the editor of Yuantai Crane. If you have other questions, you can ask us through the official website and contact information.
