Abstract Scope |
The Aluminum casthouse industry is striving for reduced operating cost, emmissions and use of energy. This does also apply to in-line removal of hydrogen and inclusions. Ten yeas ago Hycast launched the I-60 SIR unit with a unique siphoning consept and bottom mounted rotors, allowing for long residual time of the Argon gas bubbles. This reactor is drain-free and does not require any use of Chlorine or Chlorine containing salts. This unit works very well for all flow rates with only two rotors. However, for low flow rates the unit has over-capacity. The purpose of this work was to develop a one-rotor siphon inert reactor for low and medium flow rates, up to 25 tonnes per hour. Below the basic design and the metallurgical performance of the new I-25 SIR are presented. The removal efficiency of both Hydrogen and inclusions are within the requirements in the industry. |
