APPARATUS AND METHOD FOR SEQUENTIAL MELTING AND REFINING IN A CONTINUOUS PROCESS

摘要

An apparatus and a method performable with the apparatus for sequential melting and refining of materials are proposed. The materials treated in the process are converted to a liquid state of matter by heat sources. The process is particularly suitable for treating metals, semimetals and ceramics, for example in order to produce alloys and/or to refine the materials. During the method, the material goes through various treatment chambers which enable treatment at different pressure levels.

主权项

1. A method for sequential treatment of a material, wherein
a liquid material is melted and refined at different pressures in different treatment chambers, wherein the separation of the pressure levels is effected by the liquid material itself so that a continuous process is possible, the liquid material is transferred from a first treatment chamber into another second treatment chamber, wherein the transfer of the material is achieved by pressure differences in combination with electromagnetic manipulation of the flow rate between the treatment chambers, and the heat sources used in the treatment chambers work independently from each other, wherein the electromagnetic manipulation is effected by the use of means which create a moving electromagnetic field and that the manipulation comprises a deceleration and/or a stop of the flow of the liquid material, and that the pressure in the second treatment chamber is lower than that in the first treatment chamber.
