OTTO JUNKER MF induction furnaces are proven and versatile solutions refined over many years.
Designed for melting, holding and pouring any type of metal, these high-performance systems embody state-of-the-art engineering to deliver high power densities up to 1,000 kW/t cast iron or steel, user-friendly operation, and powerful process automation capabilities - backed by specific features that are tailored to the customer's individual needs and supplemented, where requested, by any of a wide range of options.
OTTO JUNKER offer a vacuum version of their medium-frequency coreless induction furnace.
Operating in the high and low vacuum range, this furnace is built in two versions.
A characteristic design feature of the first design type is that the vacuum is restricted to the melting crucible itself.
Induction coils with their supply lines for power and cooling water are placed outside the vacuum; they are freely accessible and clearly arranged in the open atmosphere. This design guarantees maximum reliability in furnace operation. It prevents glow discharges and eliminates the need for complex, vacuum-tight lead-through devices for electric power and cooling water lines. Moreover, this special design ensures that there can never be any hazardous contact between cooling water and liquid metal within a hermetically sealed area.
