Duaplate D60 Type Chromium Carbide Overlay Plate for Mining and Mineral Handling Wear Protection
HALDEN supplies Duaplate D60 type chromium carbide overlay wear plates for severe abrasion applications in mining, mineral processing, quarrying, bulk material handling, cement, steel, and power industries. The plate combines a tough weldable base plate with a hard chromium carbide overlay layer, helping protect chutes, hoppers, feeders, transfer points, bins, and liners from sliding abrasion and mineral flow wear.
Mining and Mineral Handling Equipment Fails Fast When Liners Cannot Resist Continuous Abrasion.
D60 type chromium carbide overlay plates are designed for abrasive ore, rock, coal, clinker, slag, and mineral flow where ordinary steel plate wears too quickly.
What Is Duaplate D60 Type Wear Plate?
Duaplate D60 is a chromium carbide overlay wear plate used in mining and mineral handling sectors. A D60 type plate is generally selected where severe sliding abrasion, particle flow, and liner wear are the main failure mechanisms. The original HALDEN page explains that D60 performance is related to the production process, microstructure, and chemical composition of the overlay layer.
Chromium Carbide Overlay Layer
The hardfacing layer provides the main abrasion resistance through hard chromium carbide phases distributed in the overlay matrix.
Weldable Base Plate
The backing plate provides structural support, weldability, installation strength, and processing flexibility for custom wear liners.
Custom Fabrication
HALDEN can supply full plates, cut-to-size liners, bent liners, plug-weld liners, bolt-on liners, and fabricated wear assemblies according to drawings.
Key Information Needed Before Selecting a D60 Type Wear Plate
The correct chromium carbide overlay plate should be selected by wear mechanism, liner thickness, base plate thickness, overlay thickness, material handled, impact level, installation method, and required processing.
Wear Material
Ore, rock, coal, clinker, slag, limestone, sand, ash, and mineral particles create different abrasion severity.
Plate Format
The original page notes that the format is base material + hardfacing layer. Common examples include 6+4, 6+6, 8+6, 10+8, and custom combinations.
Processing Requirement
Cutting, bending, rolling, drilling, countersinking, plug-weld holes, bolt holes, and welded assemblies should be confirmed before production.
Installation Method
Bolt-on, plug-weld, studded, direct-weld, and replaceable liner systems need different hole and edge preparation.
D60 Type Chromium Carbide Overlay Plate Features
A D60 type wear plate is built around the balance between hard overlay abrasion resistance and a tough weldable base plate. This makes it suitable for processing into mining and mineral handling liners.
| Feature | Technical Meaning | Buyer Value |
|---|---|---|
| Chromium Carbide Overlay | Hardfacing layer designed with chromium carbide phases for abrasion resistance. | Improves liner life in sliding abrasion and mineral flow applications. |
| Microstructure-Controlled Performance | Performance is influenced by production process, microstructure, and chemical composition. | Helps ensure consistent wear resistance and predictable field performance. |
| Base + Hardfacing Layer Format | Plate specification is commonly expressed as base plate thickness + overlay thickness. | Makes thickness selection easier for drawings, quotation, and wear life planning. |
| Custom Size and Processing | Plate can be supplied in standard or custom dimensions and processed according to customer needs. | Reduces site cutting, installation time, and liner fit-up problems. |
Typical Applications of Duaplate D60 Type Wear Plate
D60 type chromium carbide overlay plate is especially suitable for mining and mineral handling equipment where abrasive materials continuously slide, impact, or flow across steel surfaces.
Processing and Fabrication Options
HALDEN can supply D60 type wear plates as full plates or processed liners. For heavy equipment buyers, processed liners reduce installation work and help ensure correct fit-up on site.
Cut-to-Size Liners
Plates can be cut into rectangular, trapezoid, curved, segmented, or irregular liner shapes according to drawings.
Bent and Formed Liners
Wear plates can be formed for chute walls, hopper cones, curved liner panels, bin liners, and mineral transfer surfaces.
Hole and Fixing Preparation
Bolt holes, countersunk holes, plug-weld holes, lifting holes, slots, and custom fixing patterns can be prepared before shipment.
Welded Wear Assemblies
HALDEN can fabricate D60 type wear plates into hoppers, chutes, pipe sections, elbows, boxes, and custom wear-resistant assemblies.
D60 Type Wear Plate Selection Guide
The right plate should be selected by wear severity, liner thickness, impact level, equipment geometry, and replacement strategy.
| Requirement | Recommended Direction | Buyer Note |
|---|---|---|
| Severe sliding abrasion | D60 type chromium carbide overlay plate | Suitable for ore, mineral, coal, clinker, slag, and other abrasive material flow. |
| Moderate impact plus abrasion | Use thicker base plate with suitable overlay thickness | Base plate thickness should support impact load and fixing strength. |
| Need replaceable liner system | Bolt-on or countersunk wear liner | Useful when liners are changed during maintenance shutdowns. |
| Need no exposed bolts | Plug-weld wear liner | Recommended where bolt heads would be directly attacked by material flow. |
| Need curved surface protection | Bent or rolled D60 type wear liner | Bending radius, overlay direction, and liner geometry should be confirmed before production. |
Quality Control Points
For D60 type chromium carbide overlay plates, buyers should check overlay thickness, base plate thickness, hardness, surface condition, bonding, cutting accuracy, hole position, and drawing compliance.
