摘要： The invention relates to a method for splitting an electrically conductive liquid, in particular a melt jet, comprising the steps providing the electrically conductive liquid which moves in a first direction (12) in the form of a liquid jet (10); and generating high-frequency travelling electromagnetic fields surrounding the liquid jet (10) which travel in the first direction (12) and accelerate the liquid jet (10) in the first direction (12), thereby atomizing the liquid jet (10).

摘要： In a thermal or thermochemical treatment, metal workpieces together with a metal guide are arranged on a batch carrier. The present invention relates to a device for flow guidance for metallic pieces during such thermal or thermochemical treatment and quenching, as well as methods using the same. The fluid guide particularly ensures a uniform cooling of an inner and/or outer lateral surface of the workpieces during the quenching process.

摘要： The invention relates to a levitation melting process and an apparatus for producing castings comprising a ring-shaped element of a conductive material for introducing the casting of a molten batch into a casting mould. In the process, the ring-shaped element is introduced into the region of the alternating electromagnetic field between the induction coils in order to cast the molten batch, thereby initiating a targeted run-off of the melt into the casting mould by influencing the induced magnetic field.

摘要： The invention relates to a levitation melting method and an apparatus for producing casting bodies with tilted induction units. During this method, induction units are employed in which the opposing ferrite poles with the induction coils are not arranged lying in one plane, but tilted at a determined angle to the levitation plane. In this way, an increase in efficiency of the induced magnetic field for melting the batches can be achieved with the induction units. The tilted arrangement increases the portion of the induced magnetic field that effectively contributes to the holding force of the field for levitation of the melt.

摘要： Melting plant having a melting chamber which by way of a gas protection hood is separated from the environment, wherein the gas protection hood or another part of the melting chamber encasement has a lead through in which an electrode rod for moving an electrode to be melted is guided in a gas-tight manner by way of a sealing means. Hydraulic or pneumatic equalisation means, for exerting on the electrode rod equalisation forces which are in a proportional correlation with the gas pressure prevailing within the melting chamber are provided so as to compensate for the gas-pressure forces acting on the electrode rod.

摘要： A method and a device for closed-loop control of an electrode gap in a vacuum arc furnace subjects an electrode gap of a melting electrode from the surface of a melt material to closed-loop control as a function of a droplet short-circuit rate. For this purpose, a histogram of detected droplet short-circuits is created on the basis of at least one droplet short-circuit criterion. The histogram is subdivided into sub-areas, a characteristic sub-area of the histogram is selected for closed-loop control purposes. The electrode gap is subjected to closed-loop control on the basis of the droplet short-circuits which can be associated with the selected sub-area.

摘要： A mobile melting device for consolidating contaminated scrap and to a corresponding method. The melting device has a crucible chamber and a crucible base. The crucible is arranged on the crucible base during operation, and the crucible base and the crucible chamber together form a gas-tight furnace housing. It is thus possible to carry out the method in a vacuum or under protective gas such that even a reactive material can be consolidated. The melting device can be assembled and disassembled with little effort.
