摘要： Die Erfindung betrifft eine Vorrichtung (1) zur Herstellung eines, insbesondere metallischen, Gussstückes, bevorzugt als Vormaterial, umfassend eine Temperierungsanlage, wobei die Vorrichtung (1) einen Tiegel (2) aufweist oder mit einem Tiegel (2) koppelbar ist, um im Tiegel (2) befindliches fließfähiges, insbesondere metallisches, Material in einem Einsatzzustand der Vorrichtung (1) zur Herstellung des Gussstückes durch Kühlung mit der Temperierungsanlage im Tiegel (2) erstarren zu lassen. Um eine hohe Güte bzw. Qualität des Gussstückes zu erreichen, ist erfindungsgemäß vorgesehen, dass mit der Temperierungsanlage eine Temperaturdifferenz zwischen einer ersten, insbesondere unteren, Region (A) und einer zweiten, insbesondere oberen, Region (B) des Tiegels (2) einstellbar ist, um zur gerichteten Erstarrung des Materials einen Temperaturgradienten im Material zu bewirken.
Weiter betrifft die Erfindung ein Verfahren zur Herstellung eines, insbesondere metallischen, Gussstückes, bevorzugt als Vormaterial.

摘要： A replaceable melting furnace (2) includes a replaceable furnace body (21) having a main body (211) that has an open end (213) and that defines a receiving space (214) therein, and a partition plate (212). The receiving space (214) is divided into an upper space (215) and a lower space (216). The partition plate (212) extends from the open end (213) into the upper space (215) to divide the upper space (215) into first and second subspaces (2151, 2152) that are fluidly communicated with each other through the lower space (216). A method for producing the aforesaid replaceable melting furnace (2) is also disclosed.

摘要： The present invention relates to a method for recovering a metal from a slag containing the metal, in which the metal-containing slag is heated in at least one stirred tank reactor (2), and in which the liquid slag in the stirred tank reactor (2) is stirred by means of an appropriately directed magnetic field, wherein the slag is periodically stirred. The invention further relates to a device for recovering a metal from a slag containing said metal, comprising a stirred tank reactor (2) for heating the metal-containing slag and an electromagnet (13, 14) for generating a magnetic field in such a way that the liquid slag is stirred, wherein a switching device (15) is provided for the periodic operation of the electromagnet (13, 14).

摘要： A device for loading crucible furnaces comprises a container having an over¬ turned frustoconical side wall that abuts against the edge of a conical base sup¬ port with upwardly-directed vertex. The device is equipped with a vertical slide guide of the side wall with respect to the base support and two pairs of brackets engageable by a forklift and respectively connected to the base support and to the side wall. The lifting of the base allows lifting the entire device whereas the lifting of the side wall allows emptying the container. The base support is welded to four legs, by means of which the device can be positioned above the loading mouth of the crucible furnace; the legs are shaped in a manner such that the base support is partially inserted in the crucible.
