Embodiment Construction

[0014] In order to achieve this object, the present invention starts from the following cognitions:

[0015] figure 2 shows the passage of the Peirce-Smith-converter in the nozzle region (according to figure 1 ), wherein the nozzle 10 can be seen here, which extends from the outside through the metal casing 12 and the refractory lining 14 into the region of the converter, in which the molten metal 50 is located.

[0016] figure 1 and 2 The converter is shown in a position called the "working position". The nozzle 10 therefore extends approximately horizontally in this position and in a plane perpendicular to the likewise approximately horizontally oriented longitudinal axis L-L of the converter. The mouth region 10m slightly rises above the refractory lining 14 (in the exemplary new installation shown here).

[0017] A number of such nozzles 10 are arranged at a distance from each other along an imaginary straight line at the longitudinal side of the converter, as schema...

Abstract

The unit has a set of injectors (10) extending through an outer metal casing (12) and an inner fire resistant lining (14) for injecting treatment gas i.e. air, on molten metal (50) over respective nozzle openings (10m). Gas flushing devices are arranged beneath the corresponding injectors for injecting the gas on the molten metal, such that the molten metal is raised over the lining and flows through the nozzle openings. The flushing devices have aligned or unaligned porosity, such that cavities with a diameter less than 10 mm are formed in the molten metal over the flushing devices.

Description

technical field [0001] The invention relates to a metallurgical smelting and processing assembly, in particular to an approximately cylindrical vessel for receiving and processing non-ferrous metal melts. Background technique [0002] In particular the following assemblies / vessels belonging to these metallurgy: [0003] Peirce-Smith-converter, Teniente-converter, Noranda-reactor, copper-refining furnace. [0004] The basic configuration of this assembly for the melting of metal and for the containment and handling of the molten metal is as follows: [0005] - The vessel / furnace has an approximately cylindrical shape, wherein the longitudinal axis of the cylinder extends approximately horizontally in the functional position of the vessel. For the Peirce-Smith-transformer case, it is in figure 1 shown in . [0006] - The vessel has an outer metal casing and an inner refractory liner. [0007] - the vessel is produced with a plurality of nozzles, which are guided from the ...
