Loader & excavator buckets made of chromium carbide overlay wear plate, Increased service life of the bucket
Wear loader bucket is made of Chromium Carbide Overlay Plate. And we are one of the few who can produce this hardfaing excavator bucket. The surface hardness can be up to HRC 55-65, then it keeps a very good corrosion protection and severe abrasion resistant, widely be used in mining industry, coal power industry, port etc.For mining and coal industry, no matter what minerals you are mining, there is no escaping the abrasion experienced by mining equipment. Our hardfacing bucket is more wear resistant and its service life can be 3-5 time longer than normal material bucket.
1.General Product Description
Zhengsheng series overlay wheel bucket, is different from the traditional process, the whole wheel bucket is made of surfacing welding wear-resistant steel plate, and it is easy to wear but not easy to replace the parts with additional wear-resistant protection. our products is suitable for coal, ore yard,heave restance, medium impact material and bulk material yard.
2.Key Benefits
●Delivers improved wear life, increase payload and service life, 8 times longer service life
●Optimized to fight sliding wear, guaranteed hardfacing layer properties
●Reduce the downtime caused by damage replacement time, improve edfficiency
●In the factory to do shot blasting and sandblasting treatment, to release the stress, do anti-corrosion wear protection, improve the service life.
3.Typical Applications
| operation environment | ore and coal terminal, short haul feeder system, short haul, palletizing and loding, storage yard clear |
| operation ore categories/sort | coal, coke, iron ore, ect similar mineral products |
4.Standard Dimensions
●We have rich experience in the manufacturing of bucket, according to the specific conditions and needs, to do targeted design and production of the bucket, to maximize the service life of the product.
●We can also make it according to the drawings provided by the purchaser.
5.Customer Case
| Ore terminal short haul | Ore terminal railway loading |
| Application: Excavator bucket | Application: Loader bucket |
| Wear part:cutting edge | Wear part:bucket |
| Purpose: Increase payload and service life | Purpose: Increase payload and service life |
| Type of wear: Sliding wear and some impact | Type of wear: Sliding wear and some impact |
| Benefit: Service life increased by 500% with overlay plate compared to mild steel | Benefit: Changing from hot rolled wear-resistant steel to chromium carbide overlay wear plate increased service life from 10 months to 3 years |
6.Mechanical Properties
●Surface hardness
| Number of overlay passes | Typical surface hardness |
| Double or multiple | 59 to 62 HRC (675 to 750 HV) |
NOTE：Surface hardness is measured on machined flat surface just below overlay surface
●Wear Properties
| Number of overlay passes | ASTM G65 – Procedure A weight loss | |
| Surface | 75% depth | |
| Double or multiple | 0.16g maximum | 0.16g maximum |
NOTE：1.ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.
2.ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top
