The floating rust on the surface of the steel wire rope does pose a safety hazard. The floating rust is mainly caused by the corrosion of the exposed base material due to the damage or falling off of the surface facial mask caused by the external environmental factors (such as rain, hail, dust, harmful gas, etc.) during the use of the wire rope. The following are specific safety hazards caused by floating rust:

Reduced mechanical performance: Floating rust can cause a decrease in the mechanical performance of steel wire ropes, such as thinning of wire diameter, loosening between strands, and even brittle fracture. This type of fracture is often "avalanche like" and more dangerous than ordinary wire breakage or wear.

Impact on service life: Floating rust can accelerate the corrosion process of steel wire ropes, leading to a significant decrease in their strength and durability. According to the degree of corrosion, the strength loss of steel wire rope can reach more than 10% to 25%, seriously affecting its service life.

Difficult to detect internal corrosion: Floating rust is often only a surface phenomenon, while internal corrosion is more concealed and difficult to detect. Internal corrosion will further weaken the structural strength of the steel wire rope and increase the risk of fracture.

Impact on safety: The safety of steel wire ropes is crucial in key equipment such as lifting machinery and elevators. Floating rust and internal corrosion can seriously affect the load-bearing capacity and reliability of steel wire ropes, thereby threatening the safety of equipment and personnel.

Environmental pollution and health risks: Unresolved floating rust may cause pollution to the environment when dissolved in media such as rainwater or tap water. Meanwhile, if steel wire ropes containing floating rust are used for food processing or transportation of drinking water, harmful substances in the floating rust may also be introduced into the body, posing a potential threat to health.

To prevent the generation and expansion of floating rust on steel wire ropes, the following measures can be taken:

Regularly inspect and maintain steel wire ropes, promptly detect and address floating rust and corrosion phenomena.

Apply specialized protective grease or coating on the surface of the steel wire rope to reduce the erosion of the steel wire rope by external environmental factors.

Strengthen the protective measures of equipment, such as installing rain covers, dust covers, etc., to reduce the contact between steel wire ropes and harsh environments.

For steel wire ropes that have already developed floating rust, repair or replacement should be carried out according to the degree of rust to ensure their safety and reliability.
