Excavator plays an important role in mining equipment. As an important component of the excavator, bucket is extremely easy to suffer from abrasive wear during work, which greatly reduce its service lifetime.

The reasons of bucket wear failure are:
The human factor: workers lack responsibility, the technical level is low
Environmental factors: poor working condition, too much sulfide ore and rock strata
Original bucket design is not reasonable

The original excavator bucket can work as long as 6000 hours, and each excavator bucket needs to be replaced after 1-2 years if it works 3000 hours a year,maintenance work and cost of excavator bucket occupies a relatively large proportion of whole working process. The importance of chromium carbide overlay wear resistant steel plate on bucket has been fully proved by each experience,to prolong the bucket service lifetime, and save production cost.

In view of the short lifetime of bucket ,resulting in high production cost, users turn to use chromium carbide wear plate to prolong the service lifetime of the bucket. Chrome carbide overlay plate cab be cut into different size and then welded to bucket, it was well accepted by users for its excellent wear resistance.
