Graphite Rotor for Molten Aluminum Degassing
Product Overview
Jincheng graphite rotors for molten aluminum degassing are precision-machined graphite components designed for rotary degassing of molten aluminum and aluminum alloys. These rotors provide efficient hydrogen removal and inclusion separation for high-quality aluminum casting production.
Our degassing rotors are manufactured from high-density, fine-grain isostatic graphite that withstands the harsh environment of molten aluminum at temperatures up to 750°C. Custom shaft and impeller designs are available to match different degassing units and furnace configurations.
Key Features
- Excellent corrosion resistance against molten aluminum and aluminum alloys
- High density graphite for longer rotor life in molten aluminum
- Precision machined impeller design for efficient gas distribution and mixing
- Good thermal shock resistance for repeated immersion and removal cycles
- Custom shaft lengths for various furnace depths and degassing unit configurations
- Various impeller designs for different degassing process requirements
- Easy to install and replace during routine degassing unit maintenance
- Cost-effective compared to imported degassing rotors

Frequently Asked Questions
Q1: How long do degassing rotors last?
A: Rotor life depends on aluminum temperature, alloy type, and degassing frequency. Under typical aluminum die casting conditions, graphite rotors last 1-3 months before needing replacement.
Q2: Can you manufacture rotors based on my degassing unit model?
A: Yes, we manufacture custom rotors based on your degassing unit model or existing rotor dimensions. Please provide your degassing unit model or rotor drawings for quotation.
Q3: What is the difference between solid and hollow shaft rotors?
A: Hollow shaft rotors allow degassing gas (nitrogen or argon) to flow through the shaft to the impeller, which is the standard design for most rotary degassing systems. Solid shafts are used for simpler injection degassing systems.
Q4: Do you offer different impeller designs?
A: Yes, we offer various impeller designs including flat disk, paddle, and spiral types, each optimized for different degassing process requirements and furnace sizes.
