Channel-type induction holding furnaces
The OTTO JUNKER channel-type induction furnace is used where liquid metal must be held, stored, superheated or poured in large quantities.
Moreover, a large holding furnace can be used to equalize the carbon concentrations of different melts from a cupola.
It is the perfect answer to any of the following requirements:
- meet varying molten metal demands of the mould line
- provide permanent supply of molten metal with maximum utilization of the melting plant
- ensure utilization of low night-time power tariff for electric melting
Essential benefits of the channel-type induction furnace
- Separate filling and pouring siphons
- Furnace filling and pouring operations may proceed at the same time
- No ingress of atmospheric oxygen, i.e., slag formation is reliably prevented
- Quickly replaceable, water-cooled inductors with directed flow are available with:
- single loop up to 1,200 kW
- double loop up to 2,800 kW
- Space-saving design of switchgear and control equipment relying on mains-frequency or advanced IGBT frequency converter technology
- Additional backward tilting feature facilitates slag removal from the bath surface
