The steel for anchor chains needs high-performance green steel plates that can meet the requirements of the new shipbuilding industry standards.
Anchor chain steel takes the high-strength steel used on large bulk carriers, container ships, oil tankers and offshore engineering ships as examples. At present, the proportion of high-strength plates (A32-A36) used on bulk carriers and container ships is more than 60%. The proportion of high-strength boards is about 30%. Do you know how to maintain the anchor chain? Let's discuss it with you today.
Maintenance of anchor chain:
1. The tightness of the anchor chain should be appropriate. Too tight increases power consumption and bearings are easy to wear; too loose chain is easy to jump and fall off.
2. The anchor chain is too long or stretched after use, making it difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number. The chain link should pass through the back of the chain, the lock piece should be inserted outside, and the opening of the lock piece should face the opposite direction of rotation.
3. After the anchor chain is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. It is not possible to just replace a new chain or a new sprocket alone.
4. The old chain of the anchor chain cannot be mixed with part of the new chain, otherwise it is easy to have an impact in the transmission and break the chain.
