SGI steel degassing mechanical vacuum pump-set module lines are based on:
For VD process 3, 4 and 5- stage vacuum degassing line system. For VOD/RH process 2 to 3 stages
Prefabricated VD/VOD/RH machine stage / Suction capacity 40 000 to 177 000 m3/h with final vacuum <1 mbar
Three stage VD vacuum module line system
The SGI machine installation in a three stage steel degassing line consisting of a (HV) high vacuum rotary piston blower as first stage to the evacuation side and in the second stage a pre-inlet cooled rotary piston blower from Aerzener Maschinenfabrik. The third stage is a special dry screw vacuum pump.
Four stage VD vacuum module line system
The SGI machine installation in a four stage degassing line system consisting of a (HV) high vacuum rotary piston blower as first and second stage to the evacuation side and in the third stage a pre- inlet cooled rotary piston blower from Aerzener Maschinenfabrik. The fourth stage is a special dry screw vacuum pump.
Five stage VD vacuum module line system for very large systems or very low energy consumptions.
