The dredging wearing parts wear problems have not been solved yet, this is not only affects the production and also increase repair work labor intensity, the money they spent on maintenance runs into millions every year. Engineering damages caused by shut-down maintenance beyond imagination, and has become a big problem of equipment management.

In the mechanical equipment , the loss caused by abrasive wear is amazing, more than 60% parts failure is caused by wear and tear according to statistics. The dredger is often encountered in rock or hard substrate and harsh working conditions in dredging operations, all these serious abrasive wear has shorten the service life of total dredging working system.

Successful applications of YAOYU VAUTID wear resistant steel plate has been accepted as the most effective way to solve abrasive wear problems of dredger. YAOYU wear resistant overlay plate is produced by open arc welding process, which belongs to the hardfacing compound material. Application and experimental data prove that the performance beyond to the traditional wear resistant materials due to its excellent wear resistance and high hardness, such as casting parts, high manganese steel and HARDOX steel.

Reasonable selection of wear and abrasion resistant material, reasonable design of dredger, strengthen management in the use, the resulting benefits will be far more than the cost of improving.
