Embodiment Construction

[0037] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0038] Refer below figure 1 with 2 The furnace body 1 of an electrothermal depletion furnace for copper smelting slag according to an embodiment of the present invention is described.

[0039] exist figure 1 with 2 In the example shown, the furnace body 1 of the electrothermal depletion furnace for copper smelting slag is a horizontal cylindrical vessel, but the present invention is not limited thereto. The furnace body 1 includes a furnace shell 1a defining a furnace, and a refractory material layer 1b provided on the inner wall of the furnace shell 1a. The body of furnace 1 is formed with a charging port 11, a siphon port 12, a slag discharge port 13, an electrode socket 17, a smoke exhaust port 14, and an oxygen lance socket 16 formed at the bottom of the furnace shell 1a.

Abstract

The invention discloses an electrothermal copper-smelting slag depleted furnace body. The furnace body comprises a furnace shell defining a furnace chamber and a refractory material layer arranged on the inner wall of the furnace shell. The furnace body is characterized in that: the furnace body is provided with a feed inlet for feeding copper-smelting slag and vulcanizing agent into the furnace chamber, a siphon inlet for discharging copper matte, a waste slag-discharging outlet, electrode plugholes, a smoke outlet and an oxygen lance plughole, wherein the oxygen lance plughole is formed at the bottom of the furnace shell. When the electrothermal copper-smelting slag depleted furnace body is used for bottom-blowing electrothermal copper-smelting slag depletion, the copper content in waste slag can be reduced, and electricity consumption can be decreased.

Description

technical field [0001] The invention relates to a furnace body of an electrothermal depletion furnace for copper smelting slag, in particular to a furnace body of an electrothermal bottom blowing depletion furnace for copper smelting slag. Background technique [0002] At present, in order to reduce the blowing load, large-scale copper smelters using advanced smelting technology all adopt higher copper matte grades, that is, the output copper matte grades are higher, and the copper content in the higher-grade copper matte is 50%. In the range of ~70%, the copper content of copper smelting slag fluctuates in the range of 2% ~ 8%. [0003] In order to recover the copper in the copper smelting slag, the copper smelting slag is traditionally depleted by an electric furnace. The copper smelting slag is added to the electric furnace, and the copper smelting slag is heated by electrode heating so that the copper in the copper smelting slag settles in the form of copper matte.
