Product Description
Wrought-Aluminum Crystallizer for Aluminum Billet Direct-Chill Casting System
Product Overview

This wrought-aluminum crystallizer is engineered for aluminum billet direct-chill casting systems, featuring forged aluminum alloy construction with superior thermal shock resistance and dimensional stability under prolonged high-temperature water-cooling service.

Key Specifications & Features
Core Substrate Material: Forged wrought-aluminum alloy with compact metallographic structure and zero porosity. Material certification required - reject substrates with sand holes, voids, or micro-cracks.
Inner-bore Machining Precision: Strict tolerances for circularity and coaxiality. Proper inner-cavity taper offsets thermal expansion and prevents rod jamming. Precision-machined seating slots for graphite rings eliminate surface defects.
Water-jacket Structure: Uniform cooling passages with orderly jet orifices for consistent cooling output. Full penetration welds with hydrostatic pressure testing ensure leak-free operation. Heat-resistant silicone gaskets maintain sealing integrity.
Matched Graphite Rings: High-density fine-grain graphite with superior self-lubrication and thermal stability. Prevents dross generation, chipped edges, and surface abrasions on aluminum bars.
Operating Compatibility: Compatible with various ingot diameters, casting velocities, and alloy grades (including 6-series and 7-series alloys with distinct cooling parameters).
Performance Benefits
  • Superior thermal shock resistance and dimensional stability
  • Eliminates surface scuffing and permanent scratches on aluminum rods
  • Prevents ingot defects including fractures, bamboo-ring marks, and segregated nodules
  • Yields aluminum rods with smooth surfaces and reduced cold shuts
  • Minimal housing deformation under thermal load for extended service life
Quality Assurance

Factory test documentation includes base-material certificates, hard-anodized coating thickness inspection reports, and hydrostatic test records. Practical field performance serves as the ultimate evaluation standard.
