How can open-type equipment achieve nitrogen sealing? For example, in the case of equipment with a circular opening, is it possible to create a gas curtain by installing nitrogen nozzles at the top of the equipment in order to achieve nitrogen sealing?
Do you mean something like a gas curtain? But nitrogen is less dense
Yeah, an air barrier. But experiments were conducted and the results weren’t satisfactory; it seems that a cover is necessary
If it’s blown by an air curtain, the nitrogen consumption would be too high, right? And the effect isn’t good either. Add a lid made of lightweight material.
Add a layer of balloon-like membrane:D
Accidentally came here; it looks so much like the coated ships from One Piece
Yes, adding a graphite cover has improved things a bit, but refilling is needed from time to time, and the process isn’t very convenient
Are open containers still allowed to be used? Now, solid materials are added using sealed feeders; it’s no longer possible to add them by manually opening the container
Mid-frequency furnace, open-type; desire to use gas sealing for oxygen removal during melting
I haven’t dealt with this before, so I’m not very familiar with it
