How ZZ OLD CRAFTSMAN supply for mining tungsten carbide chute Liner plates solution

Supplying a tungsten carbide (WC) wear chute liner solution for mining involves several key steps, from material selection to installation and maintenance. Below is a structured approach to providing an effective solution:

1. Assess Application Requirements

Material Being Handled: Abrasiveness, particle size, moisture content (e.g., iron ore, coal, slag).
Operating Conditions: Impact force, temperature, flow rate, and angle of chute.
Existing Wear Issues: Identify failure modes (e.g., abrasion, impact, corrosion).

2. Design the Tungsten Carbide Liner Solution

Material Selection:
- WC Grades: Choose between cast tungsten carbide (CTC), sintered WC, or WC-Ni/Co binders based on wear vs. impact resistance needs.
- Hardness vs. Toughness: Higher cobalt content (6-12%) improves toughness for impact; lower cobalt (3-6%) maximizes abrasion resistance.
Liner Configuration:
- Tiles/Blocks: Prefabricated WC tiles (e.g., 10mm–50mm thick) bolted/welded to steel backing.
- Composite Liners: WC embedded in steel matrix for hybrid strength.
- Custom Shapes: Conformed to chute geometry (e.g., curved, flat, or stepped designs).

3. Manufacturing & Fabrication

Production Methods:
- Sintering: Pressing and sintering WC powder for high-density liners.
- Brazing/Welding: Attaching WC tiles to steel substrates via high temperature brazing or overlay welding.
- 3D Printing (Emerging): For complex geometries using binder-jet WC.
Quality Checks: Density testing, hardness (HRA 85–93), and microstructure analysis.

4. Supply Chain & Logistics

Supplier Partnerships: Work with reputable tungsten carbide manufacturers (e.g., Kennametal, Sandvik, Ceratizit) or specialized wear solution providers.
Lead Time: Sintered WC liners may require 4–8 weeks; stock items are faster.
Packaging: Shock-resistant packaging to prevent brittle fracture during transit.

5. Installation & Maintenance

Mounting Methods:
- Mechanical Fastening: Bolts with countersunk WC tiles for easy replacement.
- Adhesive Bonding: Epoxy or ceramic adhesives for secondary retention.
Inspection Schedule: Monitor wear every 3–6 months; replace tiles at 50% wear depth.

6. Cost Optimization

Zoning: Use thicker/higher grade WC in high wear zones (e.g., impact points) and lower cost materials elsewhere.
Lifecycle Cost Analysis: Compare WC’s longevity (often 5–10× longer than steel) vs. upfront cost.

7. Complementary Solutions

Hybrid Liners: Combine WC with UHMWPE, alumina ceramics, or AR steel for cost efficiency.
Flow Aids: Coatings or chute redesign to reduce wear (e.g., steep angles, rock-box designs).
