Embodiment Construction

[0018] With reference to the instructions and accompanying drawings, the high-oxygen-enriched bottom-blown low-energy-consumption molten pool smelting technology of the present invention is described in detail as follows:

[0019] A high-oxygen-enriched bottom-blown low-energy molten pool smelting technology, the oxygen lances 2 are arranged in double rows vertically at a certain angle, and are arranged crosswise at the bottom of the furnace body 1 and one side within three-fifths of the end of the main burner 9, The feed port 5 is set at the upper part of the furnace body 1 corresponding to the oxygen lance 2, and the matte discharge port 6 is set at the bottom of the furnace body 1 at the end of the auxiliary burner 10. The slag outlet 7 is arranged at the middle and lower part of the end face of the furnace body 1, and the flue dust duct 8 is arranged at the upper part of the furnace body 1 at the end of the auxiliary burner 10.

[0020] The high-oxygen-enriched bottom-blow...

Abstract

The invention provides a high oxygen-enriched bottom blowing low power consumption molten pool melting technology, relating to non-ferrous metallurgy. The invention includes oxygen guns, high oxygen-enriched air, copper matte, slag, mineral aggregate and a flue; wherein the high oxygen-enriched air is ejected into copper matte in a melting pool from bottom to top in a crossing and high-speed way by virtue of a plurality of oxygen guns arranged at the bottom of a furnace body, under the condition of fully mixing and contact, instant vigorous oxidation is taken place, high energy heat is released, and the process that mineral aggregate is melted into matte and slag can be completed without adding any fuel. Compared with the prior art, the invention has the advantages that no fuel is required to be added in the melting process, energy is saved, oxygen is saved, no carbon dioxide is discharged, mineral aggregate extensive manner is adopted, production scale is easy to control, and multi-metal capturing ratio is high, and the service life of oxygen gun is obviously prolonged. Thus the invention has good popularization and use values.

Description

1. Technical field: [0001] The invention belongs to non-ferrous metallurgy, in particular to a high-oxygen-enriched bottom-blown low-energy-consumption molten pool smelting technology. 2. Background technology: [0002] Non-ferrous metallurgy under the existing technology mainly includes flash smelting, double flash smelting, top blowing smelting, Noranda side blowing smelting, Vanyukov smelting and so on. The practical applications of these technologies are all based on their unique innovation advantages, but none of these technologies have broken through the industrial limitations and deficiencies of nonferrous metallurgy, mainly manifested in: large production scale, large investment, large energy consumption, heavy pollution, High requirements for mineral materials, poor adaptability, and low metal capture rate lead to the abandonment and waste of resources, rapid loss of equipment parts, and frequent repairs and maintenance. 3. Contents of the invention: [0003] The...
