기술사양

Multiple Charging Systems:
• Large capacity overmelt chargers for primary bucket charging of high density charge materials.  Charge weights to 5t are possible depending on the furnace refractory dimensions. Large capacity chargers incorporate dual hoists to allow controlled opening of charge buckets.
• Secondary overmelt devices for temperature probe insertion, sample taking, and late alloy additions
• Overmelt chargers utilize a custom-designed water-cooled overmelt isolation valve to over 1.3 m in diameter incorporating vacuum seal protection when open for increased reliability
• Vibratory side feeders for primary charging of low density charge materials
• Other charging systems for low headroom installations are available

Vacuum System:
• Three stage vacuum pumping system incorporating oil sealed rotary pumps or dry type screw pumps, roots type mechanical blowers, and oil vapor booster pumps for finalizing vacuum levels in the 10-3 Torr range
• Oil wetted vacuum filters for control of pyrophoric additions such as NiMg
• Large electrode VIM systems may incorporate steam ejector or steam hybrid vacuum pumping systems
• State-of-the-art safety systems incorporating overpressure relief valves and argon purging

Mold Pouring:
• Hot tundish insertion chargers configured to insert an externally preheated refractory tundish into the pour position within a few minutes
• Deep tundishes on large furnaces can contain stopper rod assemblies
• Programmable control of mold car / turntable movement

Controls:
• Computerized control and SCADA systems
• TV cameras on remotely actuated site ports for remote operation

Accessories

Two furnace layouts are typically utilized: Rollaway Head and Door Mounted Furnace.

Rollaway Head furnaces have the following features:
• Good access to the furnace top and spout
• Simple power supply bus arrangement
• Good ability to inspect the lining and furnace coil
• Able to frit lining or perform wash heat in open air

Door Mounted Furnaces have the following features:
• Very easy access to melt chamber for cleaning
• More complicated power supply bus required
• Easy access to all of coil
• Less platforming required since there is no head movement
