Abstract
The present invention relates to an oven for heating an essentially liquid medium, especially a reactive casting material, flowing through the oven. The oven has an inlet into a channel for the medium to be heated, in which channel there is arranged a separate pipe through which the medium to be heated flows and in which it is heated by electromagnetic radiation. Several heating units are arranged along the channel, each of which comprises an electromagnetic radiator containing a waveguide. The waveguides guide the radiation to the channel through which the medium flows and which couples the radiation into that channel. The heating units are substantially decoupled from one another by means of a decoupling diaphragm that is provided in the channel and is arranged between two adjacent heating units or radiators essentially at right angles to the direction of flow. The pipe through which the medium flows passes through a passage in the decoupling diaphragm, thus also constituting a support for the pipe.
