Graphite and Carbon Shaft Tube in the Aluminium Industry

Graphite and Carbon Shaft Tube in the Aluminium Industry   Graphite Tubes and Shaft  which is made of high purity graphite, quality of graphite can affect the usage life of rotor, our product has the anti-oxidation protective coating, so the usage life will be extended to 50-60 days. Graphite shafts and graphite impellers are used in rotary purification systems for aluminium degassing. Graphite is used due to it's heat and chemical resistant properties.
  Proprietary technology
Working description of graphite rotors: Graphite rotor is make up the shaft and blow head.The rotary rotor breaks the insufflated nitrogen (or argon) in the Aluminum fusant into numbers of dispersing bubbles, which are spreading in the metal liquid. As a result of gas partial pressure difference and surface absorption, the bubble absorbs the hydrogen and oxide and removes the gases out of the fusant as it rises, so as to purify the fusant. The bubble is small and dispersing, mixed well and twistly and slowly rises with the rotary fusant, keeps a long touch with the fusant, so the airflow will not arise and the purifying performance can be notably improved.    Usage technique of graphite rotor operation:  Preheating first before usage: reheating 5min-10min on above of liquid level 100mmbefore immerging graphite rotor into aluminum fusant, avoid of effect to material from emergency cooling. And before immerging the rotor into liquid , gas must be put in, stop inputting gas after putting forward the rotor, in order to avoiding jam from air hole of rotor spray nozzle.   Graphite rotors, impellers and shafts for aluminum gas injections systems, Advantages: 1. Excellent oxidation resistance 
2. Rotor designed for good gas dispersal 
3. Vane rotor to reduce bubble size for better hydrogen removal 
4. Efficient removal of hydrogen and unwanted particles 
5. One piece construction  6. Long time durable, cost effective
Applications  For aluminum liquid agitating inside furnace; matching graphic rotor in aluminum industry. In the aluminum and zinc casting industries, nitrogen, argon or carbon tetrachloride are injected and sprayed into molten metal through graphite rotors for dehydrogenation. It can eliminate the bubbles inside the castings and improve their inner quality. Injects inert gases into the Metallic solution 

Typical sizes 
- Graphite rotor rod: Diameter: 50 - 150mm Length: 500 - 1200mm 
- Graphite rotor head: Diameter: 100 - 300mm
