Problems solved by technology

However, integration of the refractory material of the weir in the refractory lining of the entire furnace prevents easy separation of the weir from the furnace.
Therefore, most inspection and maintenance activities require a partial or complete shutdown of the furnace

Embodiment Construction

[0037] figure 1 A top submerged lance (TSL) furnace 10 comprising a weir module 100 according to the invention is shown. It should be understood that the TSL furnace 10 is shown and described in the following detailed description for purposes of illustration only. A weir module 100 of similar construction may equally be attached to other types of smelting furnaces.

[0038] first reference figure 1 , showing a TSL reactor or furnace 10 suitable for carrying out (pyro)smelting operations, spraying using a top-blown submerged lance (TSL) with a TSL lance, the TSL reactor or furnace having a Weir module 100 . A cut-away section of the furnace 10 is also shown in Figure 4 middle. Furnace 10 also has a function for containing molten bath 14 (see Figure 4 ), the molten bath contains or has a top layer of slag. The base portion 12 and roof 16 of the furnace 10 typically have a steel shell 20 internally lined with a suitable refractory material 22 ( Figure 4 ).

Abstract

A weir module (100) is provided for releasable attachment to a pyrometallurgical furnace (10) that includes at least one weir attachment section (120). The weir module (100) comprises a discrete structure to the furnace (10), and the weir module (100) includes at least one furnace engagement section (130) which is releasably engageable to at least one weir attachment section (120) of the furnace (10).

Description

[0001] priority cross reference [0002] This application claims priority to Australian Provisional Patent Application No. 2014904057 filed on 10 October 2014, the entire contents of which should be understood to be incorporated herein by reference. technical field [0003] The present invention generally relates to an interchangeable weir module for a (pyro)smelting furnace. In particular, the invention is applicable to top-blown submerged lance (TSL) furnaces, and it will be convenient to disclose the invention below in relation to this exemplary application. However, it is to be understood that the invention is not limited to this application, but may be applied to any continuously operating furnace using a weir for collecting and removing molten material. Background technique [0004] The following discussion of the background of the invention is intended to aid in the understanding of the invention. It should be understood, however, that the discussion is not an admis...
