Billet Casting Mould Tube

Product Description

TECHNICAL DESCRIPTION INFINITY COPPER MOULD TUBE

1. Product Overview

Infinity Copper Mould Tubes are high-precision components used in continuous casting machines (CCM) for steel production. These mould tubes are designed to ensure uniform solidification of molten steel, resulting in superior billet, bloom, or slab quality with optimal surface finish and dimensional accuracy.

2. Application

• Continuous Casting of:
  • Billets
  • Blooms
  • Slabs
• Steel Plants & Rolling Mills
• Non-ferrous casting (optional applications)

3. Base Material

• High conductivity Electrolytic Tough Pitch Copper (ETP Copper Cu-ETP, Cu 99.9%)
• Optional:
  • Silver Bearing Copper (CuAg 0.08%0.12%)
  • Chromium Zirconium Copper (CuCrZr) for higher strength and thermal fatigue resistance

4. Manufacturing Process

• Centrifugal casting / Forged copper tubes
• CNC precision machining (ID & OD)
• Honing and polishing of internal surface
• Multi-layer electroplating (if required)
• Strict dimensional and metallurgical inspection

5. Coating / Plating Options

• Nickel Coating (Ni):
  Thickness: 0.5 1.5 mm
  Purpose: Wear resistance, longer life
• Hard Chrome Plating (Cr):
  Thickness: 0.03 0.10 mm
  Hardness: 850 1100 HV
  Purpose: Anti-stick, abrasion resistance
• Composite Coating (Ni + Co / Ni + Cr):
  For enhanced thermal fatigue resistance and extended service life

6. Design & Specifications

  • Square
  • Rectangular
  • Round
• Size Range:
  • Billet: 80 80 mm to 200 200 mm
  • Bloom: Up to 400 400 mm
  • Slab: As per customer drawing
• Length:
  • 600 mm to 1200 mm (customizable)
• Corner Radius:
  • As per casting requirement
• Taper Design:
  • Single taper / Multi-taper / Parabolic taper
  • Designed based on casting speed and steel grade

7. Cooling System

• Optimized water cooling slots / channels
• Uniform heat extraction design
• High heat transfer efficiency for crack-free casting

8. Surface Finish

• Internal surface roughness: Ra 0.8 m
• Mirror-polished inner surface for smooth casting

9. Mechanical & Physical Properties

• Thermal Conductivity: 350 W/mK
• Hardness (after plating): Up to 1100 HV
• High resistance to:
  • Thermal fatigue
  • Erosion
  • Corrosion

10. Quality Control

• Chemical composition analysis
• Ultrasonic testing (UT)
• Dimensional inspection (CMM)
• Coating thickness testing
• Surface roughness measurement
• Hydro pressure / leakage test

11. Advantages
