Purpose of the development: The vacuum stream inoculation of cast iron.

Recommended application field: Foundry cast iron.

Advantages over analogues: Combination treatment of liquid iron magnesium-containing ligatures process vacuum cast in optimal time frame to reduce consumption by 25-30% ligatures, reduce the amount of slag generated by 2-3 times, and to exclude the bright glow of gas and smoke emission in the interaction ligation with the melt.

The development stage readiness: The working documentation is developed

Description of the development:
()
The technological process is carried out as follows: Position the bucket installed in the camera and charged with a ligature. The mechanism for moving the lid equipped with a partition, over a bucket and pressed against the seal flange. The metering hole for flowing metal in the hopper is closed plate is melted and evacuated from the chamber air (residual pressure in the range 1-5 mm Hg). Bucket similar installed in a chamber filled with the furnace. From it the metal is poured into a hopper while continuing evacuation. As the metal fills the funnel, it is melted and penetrates the plate in the form of jet into evacuation volume, filling the ladle with a ligature. In this vacuum chamber is maintained. The process of vacuum cast in a jet, combined with its treatment in the ladle ligature lasts about 30 seconds., While the dispensing opening is closed layer of melt in the funnel. Freed bucket mounted to the free chamber and the cycle repeated. Installation allows you to process up to 10 tons of cast iron per hour.
