炭化クロム摩耗プレート (CCO Plates) are bimetallic steel plates designed for extreme abrasion and impact resistance.
They consist of a high-hardness chromium carbide overlay layer に溶接された 頑丈なスチールベース, combining:

  • Exceptional surface hardness (58–65HRC)

  • 衝撃靱性 from the base steel

  • Long service life in mining, セメント, 力, and material handling industries

The key to producing a reliable CCO plate lies in precision overlay welding and quality control.

Manufacturing Process of Chromium Carbide Wear Plates

1. Base Plate Selection

  • Common base steels: Q235, S355, NM400, AR400/450

  • The base provides 構造強度, 靭性, 溶接性.

  • Thickness is chosen according to application requirements (typically 6–50 mm).

2. Overlay Material Preparation

  • Overlay is typically a chromium carbide alloy wire or strip containing:

    • 10–30% chromium (Cr)

    • 2–5% carbon (C)

    • Optional additions: で, モー, fe

  • The overlay provides hardness and abrasion resistance, forming a continuous carbide layer on the surface.

3. Overlay Welding Process

There are several methods to deposit the chromium carbide layer:

方法 説明 利点
Single/Multiple Pass Submerged Arc Welding (見た) Large plates welded with chromium carbide wire in several passes 高い成膜速度, uniform overlay
Plasma Transferred Arc (PTA) High-energy plasma welds chromium carbide powder onto plate Very high hardness and low dilution
フラックス入りアーク溶接 (FCAW) Manual or semi-automatic overlay with flux-cored wire Flexible, suitable for small or custom plates
Shielded Metal Arc Welding (スマウ) Stick welding with chromium carbide rods Simple, suitable for repair or small batches

Key factors during welding:

  • Maintain オーバーレイの厚さ as designed (3–20 mm typical)

  • Control dilution between overlay and base (<10–15%)

  • Preheat thick base plates to 150–250℃ to prevent cracking

  • Multi-pass welding with controlled cooling ensures uniform hardness and metallurgical bonding

4. Heat Treatment and Stress Relief

  • Some CCO plates undergo post-weld stress relief at 150–200°C

  • Reduces residual stress from multi-pass welding

  • Ensures dimensional stability and prevents cracking during service

5. Surface Finishing and Inspection

  • Grinding or shot blasting removes slag and spatter

  • Non-destructive testing (NDT) such as ultrasonic or dye penetrant inspection ensures overlay integrity

  • Hardness testing is done to confirm target HRC or HBW

  • Plates are カット, drilled, or prepped for shipping and installation

6. Final Quality Control

  • オーバーレイの厚さ measurement (typically 3–20 mm)

  • 硬さ試験 (surface: 58–65HRC, ベース: 200–300 HBW)

  • Visual and metallurgical inspection for cracks or porosity

  • Ensures the plate meets industry standards for mining, セメント, and heavy equipment applications

Key Advantages of the Manufacturing Process

  • 高い耐摩耗性: Hard chromium carbide surface resists sliding and impact abrasion

  • Durable base: Tough steel base absorbs shocks, reduces brittle failure

  • Customizable thickness and size: Overlay and base tailored for application needs

  • Consistent quality: Multi-pass welding and strict inspection ensure reliable performance
