摘要： Process and equipment for the treatment of loads or residues of non-ferrous metals and their alloys including the steps of loading of scraps or dross to be processed; heating the load (29) and melting the metal; revolving the heated load (29), tapping the molten metal and emptying the cavity (28) of the furnace, being the heating up of the load (29) or residues (23) to a temperature above the melting temperature of the metal or non-ferrous alloy to be recovered carried out by means of a free burning convective arc which is independent from the supply of external gas to the process, and which may dispense with the use of melting salts. The equipment for process application has the following characteristics: it comprises a closed vessel (1) which has a revolution axis around which it may be rotated or simply submitted to oscillating movement; offers the possibility of the revolution axis of the vessel (1) to rest in a horizontal position or to be tilted above and below said plane; to be heated by means of a free burning convectice arc, self-stabilized and generated by a continuous current electric discharge which, as a function of the adjustment of the tilting angle of the rotation axis of the vessel (1) and the amount of material therein fed, may be established between one single electrode (3) introduced into the furnace (1) and the load fed (29) therein or the bottom wall of the vessel (1) built of electrically conductive material (15); said electrode (3) to operate as a cathode and to be introduced through the vessel door (2), preferably according to an eccentric or inclined axis positioned above the rotation axis of the furnace (1), and which may be displaced along its axis for arc length adjustment.

摘要： The invention relates to a method and device for the continuous production of steel using metal charge material (8) that is preheated in an upper part of a melting vessel (2), is then melted in a lower part (9) of the melting vessel l(2) with fossil fuels (23) and the molten material (16) is continuously discharged into a treatment vessel (3) in which the desired steel quality is adjusted while gases (22) are introduced into the melting vessel (2) from the exterior to afterburn the melting exhaust gases (13). The aim of the invention is to improve the aforementioned afterburn step while at the same time reducing oxidation of the iron-containing charge materials. For this purpose, the process gases (13) are step-wise afterburned when ascending in the melting vessel (2) by introducing the afterburn gases (22) into the interior of the charge material column by way of an interior shaft (5) that projects into the material column and in whose walls (20) inlet openings (21) for the gases (22) are disposed and form afterburn planes (E1, E2) arranged one on top of the other. The invention also relates to a device for carrying out the inventive method.

摘要： A method and apparatus is disclosed to improve the metal yield by adjusting the tilt angle of a tilting vessel having a submerged tap hole. The tilt angle is adjusted in response to parameters inherent in the pouring process, i.e. the proximity of the vessel contents to the vessel lip, the age of the tap hole, the liquid head over the tap hole, etc. Additionally, methods are disclosed to enhance the metal yield by advancing or moving back the furnace without knowledge of the tilt angle. Moreover, such methods and apparatus can be implemented through the use of computer based algorithms. The methods can also be used to archive pouring parameter information for future uses such as training and reviewing.

摘要： A pour throat nozzle for a plasma arc centrifugal treatment system includes a substantially cylindrical throat section, with a generally arch-shaped, downwardly-facing surface at larger radii extending above the plane of the bottom of the throat section, and with this connecting to a generally cylindrical section extending below the aforesaid plane at an inside radius much larger than the radius of the throat section. Furthermore, a method of reforming an orifice of a pour throat in a PACT system centrifuge includes adding ceramic material to the melt, heating and mixing the ceramic material with the melt, then slowing rotation of the centrifuge so that the mix pours into the inlet orifice of the nozzle.
