Oxygen-rich side-blowing double-region weld pool smelting furnace

Abstract

The invention discloses an oxygen-rich side-blowing double-region weld pool smelting furnace. The oxygen-rich side-blowing double-region weld pool smelting furnace comprises a furnace body, a furnacedoor, a fuel gas system and dust removal covers, wherein the fuel gas system is mounted at the left side of the furnace body; the dust removal covers are mounted on upper positions of the front side and the rear side of the furnace body; sub air inducing tubes are mounted above the dust removal covers and communicate with the dust removal covers; the two sub air inducing tubes are gathered together and communicate with a primary air inducing tube; the primary air inducing tube is connected with a dust removal pool; a molten aluminum outlet is formed on a position close to the lower side of themiddle part of one side of the furnace body; and a slag removal device is mounted on the upper position, which is at the same side with the molten aluminum outlet, on the furnace body. The oxygen-rich side-blowing double-region weld pool smelting furnace is characterized in that a plurality of symmetrical reinforcing ribs are arranged on an outer door plate of the furnace door, so that strength of the furnace door is guaranteed. The oxygen-rich side-blowing double-region weld pool smelting furnace has the advantages of being sufficient in combustion, high in recovery rate, easy to operate, economical and applicable, in-organized, less in emission, capable of comprehensively recycling resources, energy-saving and consumption-reducing, and the like, can reduce coke consumption by 10%, improves hearth efficiency by 15%, improves product quality, and reduces power consumption and water consumption by 12%.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a melting furnace for melting molten aluminum from aluminum ingots. Background technique [0002] In the pyro-smelting process of non-ferrous metal copper, it is generally necessary to add copper concentrate, solvent and coke into the smelting furnace in a certain proportion and order, and carry out semi-self-heating or self-heating under high temperature and strong oxidizing atmosphere. Smelting, melting the copper sulfide concentrate to form a co-melt of metal sulfide - matte. Copper sulfide is enriched in copper matte in a stable low-valent sulfide state. The properties of matte and slag are very different, and they can be clarified and separated, so that matte can be put into the blowing process, and then blister copper can be produced. At present, the newly developed melting pool melting furnace type in China also realizes the complete separation of matte and slag by...

AI Technical Summary

Problems solved by technology

At present, the newly developed melting pool melting furnace type in China also realizes the complete separation of matte and slag by adding a partition wall in the furnace to distinguish the smelting zone and the settlement zone, but it requires a large hearth area, and the partition wall is long-term It is washed by the melt in a high temperature environment, and it is difficult to maintain and maintain
