For permitting temperature manipulation of a melt even at a conductivity below 10&#x3a9;cmand thus permitting refining of the melt at temperatures about 1700&#xb0; C., the invention provides a method and a device for temperature manipulation of a melt (), in particular in a refiner unit. The melt () is heated at least by ohmic resistance heating with at least two electrodes () that are arranged in the melt (). At least a part of the melt () is cooled. The device () for temperature manipulation, refining, purification and homogenisation of a melt () comprises at least one arrangement for accommodating melt material (), defining an inner chamber, and at least two electrodes () for ohmic resistance heating of the melt (). The electrodes () project into the inner chamber of the arrangement, in particular of a vessel ().

Method for temperature manipulation of a melt

A heating apparatus for the conductive heating of melts, in particular for the rapid melting-down, refining and/or conditioning of melts, is provided. The heating apparatus includes at least one electrode, as well as a first cooling system with a cooling power, which can be set and/or controlled variably.
