For copper alloy casting, Induga also supplies crucible-type coreless forehearth furnaces. They provide the flexibility needed for quick alloy changes and ensure a stable casting process even with alloys that are difficult to cast.

Option: Casting and alloying furnace

This furnace consists of two chambers and a forehearth heated by an inductor integrated into the furnace vessel: The casting alloy is filled into the first chamber, together with the precisely metered phosphorus additions. The second chamber is used for alloy holding and homogenizing.

The forehearth enables slag-free, multi-strand casting. The furnace can be hydraulically tilted and moved away from the casting position. This facilitates and accelerates production, CC mould changing and furnace emptying.

Outstanding features of this furnace option:

• Encapsulated design prevents air ingress and minimizes loss due to oxidation
• Special furnace design reduces energy consumption
• Optimal inductor position ensures intensive mixing of the metal in the filling chamber with material in the forehearth
• High-precision temperature control

Option: Casting furnace for tubes, sections and billets

This furnace consists of a main chamber with a flanged-on channel inductor and a forehearth serving as a tundish with an integrated CC mould. The optimized furnace geometry ensures that the metal temperature at the inflow into the mould is always constant.

Highlights of this furnace type:

• High-precision temperature control
• Mould and format changes in less than 10 minute
• Direct hydraulic coupling to the mould
• Encapsulated design avoids air ingress and minimizes loss due to oxidation
• Special, encapsulated furnace design reduces energy consumption
• Optimized inductor position ensures intensive metal mixing between the forehearth and the main furnace chamber
• Three hydraulically adjustable furnace positions for production, mould changing and emptying
• Low maintenance costs
