Daily Steel Wire Rope use, there will always be a variety of problems, today, Terex Xiaobian to tell you about what the corrosion of steel Steel Wire Rope, I hope you have some understanding.
External and internal corrosion
Corrosion is particularly likely to occur in the atmosphere of marine or industrial pollution. It not only reduces the metal area of the Steel Wire Rope to reduce the breaking strength, but also will cause the surface rough and start from the development of cracks and accelerated fatigue. Serious corrosion will also cause the rope to reduce the elasticity.
1, external corrosion
Corrosion of external steel wire can be observed with the naked eye. When the surface appears deep pit, the wire should be slackened when it should be scrapped.
2, internal corrosion
The internal corrosion is more difficult to find than the external corrosion that accompanies it. But the following phenomena are available for identification:
A. Steel Wire Rope diameter changes. The diameter of the Steel Wire Rope in the curved part of the pulley is usually smaller. But for the static section of the rope is often due to the outer rope rope rust caused by the increase in the Steel Wire Rope diameter.
B. Steel Wire Rope outer strands of the gap between the reduction, but also often accompanied by the emergence of outer strands broken wire.
If there are any signs of internal corrosion, the supervisor of the Nantong Steel Wire Rope for internal inspection. If there is a serious internal corrosion, the Steel Wire Rope should be immediately scrapped.
