Problems solved by technology

[0002] The utility model patent of 03246213.1 discloses an oxygen side-blowing direct lead smelting furnace, adopts the oxygen side-blowing molten pool smelting technology, adopts high and low furnace bottoms for the first time, and sets a siphon well connected with the low furnace outside the furnace, adopts siphon discharge The slag and inclined siphon lead release structure effectively solves and eliminates the intermediate layer formed in the furnace and realizes direct aluminum smelting. However, this structure is suitable for smelting lead concentrate, lead-antimony ore, antimony ore and secondary secondary production of lead. Raw materials, etc., not suitable for the smelting of copper concentrate, copper-nickel ore and other non-ferrous metal ores

Embodiment Construction

[0005] The present invention is described in detail in conjunction with the above drawings. The oxygen side-blowing direct lead smelting furnace disclosed in the 032462131 utility model patent adopts a high and a low furnace bottom 1, 2 and the inclined bottom 4 between them. There is a lead discharge port at the siphon well, and there is an oblique channel between the lead liquid discharge port and the bottom of the siphon well. This structure is more suitable because the melting point of lead is low. But for the non-ferrous metals whose melting point is up to thousands of degrees, such as copper and copper alloys, etc., this lead port and the slag port 3 share a siphon well and cannot effectively separate from the slag. In order to solve this problem, the present invention has made the following improvements on the structural basis of the above-mentioned utility model patent. A partition wall 6 is set in the original siphon well 5, forming two siphon wells 5, 7, which are res...

Abstract

The invention discloses a nonferrous metal oxygen side-blown molten pool smelting furnace and relates to extraction of a nonferrous metal. The invention provides a nonferrous metal oxygen side-blown molten pool smelting furnace applicable to smelting of copper, nickel and other nonferrous metal minerals. The technical proposal of the invention is that a nonferrous metal oxygen side-blown molten pool smelting furnace includes a furnace crucible, a water jacket, a feed opening, a smoke vent and an air opening; one furnace bottom is high and the other is low; an inclined surface is arranged between the high and the low furnace bottoms; a partition wall is arranged in a siphon well out of the wall on the front end of the furnace for separating the siphon well into a slag siphon well and a metal siphon well; a channel is arranged between the partition wall and the furnace bottoms for communicating the two siphon wells; the upper end of the slag siphon well is provided with a slag tap; the upper end of the metal siphon well is provided with a metal liquid discharge opening. The invention is used for smelting the nonferrous metal.

Description

Technical field: [0001] The invention relates to a refining of nonferrous metals, in particular to a nonferrous metal oxygen side-blowing molten pool smelting furnace. Background technique: [0002] The utility model patent of 03246213.1 discloses an oxygen side-blowing direct lead smelting furnace, adopts the oxygen side-blowing molten pool smelting technology, adopts high and low furnace bottoms for the first time, and sets a siphon well connected with the low furnace outside the furnace, adopts siphon discharge The slag and inclined siphon lead release structure effectively solves and eliminates the intermediate layer formed in the furnace and realizes direct aluminum smelting. However, this structure is suitable for smelting lead concentrate, lead-antimony ore, antimony ore and secondary secondary production of lead. Raw materials, etc., not suitable for the smelting of copper concentrate, copper-nickel ore and other non-ferrous metal ores. Invention content: [0003]...
