In numerous industries such as mining, cement production, port operations, and infrastructure construction, buckets serve as core components directly exposed to materials, constantly facing immense wear challenges. The high-speed impact and intense friction from materials like sand, gravel, ore, and slag cause buckets made from ordinary steel plates to wear out, deform, or even crack rapidly. This not only leads to frequent repairs and high costs but also severely impacts equipment availability and operational efficiency.

Shandong Qishuai Wear-Resistant Equipment Co., Ltd., with deep expertise in wear-resistant technology, has developed overlay-welded wear plates specifically for bucket equipment. These plates offer exceptional wear resistance and extended service life, making them the ideal solution for protecting buckets while reducing costs and boosting efficiency.

The Severe Wear Challenges Facing Buckets

During operation, the most intense wear occurs on the bucket lip, bottom, side plates, and tooth seats:

• Bucket Lip and Cutting Edge: Directly cuts into materials, enduring intense abrasive wear and impact.

• Bucket Bottom and Side Plates: Undergoes continuous sliding friction with materials during loading and transport, causing severe scraping wear.

• Tooth holders: The areas securing the teeth endure high-stress impacts and wear transmitted from the teeth.

Conventional buckets made of ordinary steel plates or even some lower-grade wear-resistant steels often require re-welding after just hundreds of hours in harsh conditions. Their service life is typically only a few months before replacement is needed, resulting in extremely high overall operating costs.

Qishuai Overlay Welded Wear-Resistant Plates: Custom-Engineered High-Performance Armor for Buckets

Qishuai plates employ advanced self-shielded open-arc overlay welding to deposit one or multiple layers of high-hardness, high-wear-resistant alloy onto premium low-carbon steel substrates. This composite structure seamlessly combines the substrate's toughness with the overlay's hardness, achieving optimal balance between impact resistance and wear endurance.

Core Product Advantages:

1. Exceptional Wear Resistance: The overlay layer achieves hardness up to HRC 58-62+, delivering wear resistance several times greater than standard wear-resistant steels (NM360/NM400). It effectively withstands cutting and abrasion from sharp materials.

2. Superior Impact Resistance: The tough steel substrate effectively absorbs operational impact loads, preventing brittle spalling of the overlay or plate cracking. This makes it particularly suitable for high-impact applications like excavation and loading.

3. Customizable Design: Tailored wear-resistant overlay plates can be engineered with varying thicknesses, hardness levels, and alloy compositions based on specific operational conditions (e.g., material particle size, hardness, impact angle), optimizing cost-effectiveness.

4. Easy Processing and Installation: The overlay wear-resistant plates exhibit excellent bending and welding properties. They can be cut, bent, and welded directly on-site according to the wear patterns of the bucket, much like “applying armor” to the bucket. This ensures convenient construction and short repair cycles.

Application Benefits: Delivering Tangible Value to Customers

Welding or replacing critical wear-prone areas like bucket lips, bottoms, and sidewalls with Qishuai overlay wear plates yields immediate benefits:

• Extended Lifespan: Overall bucket service life increases by 3-5 times, drastically reducing replacement frequency.

• Reduced Downtime: Maintenance intervals are substantially extended, minimizing equipment downtime for bucket repairs and boosting operational availability and output.

• Lowered Overall Costs: While the initial investment is slightly higher, the extended lifespan and minimal maintenance requirements significantly reduce hourly equipment wear costs, delivering notable economic benefits.

• Enhanced Operational Efficiency: Buckets maintain optimal shape, ensuring high fill factors and sustaining efficient loading/unloading capabilities.
