Embodiment 1

[0015]Raw miscellaneous copper with a copper content of 60.0wt% and blister copper smelted with copper matte; the configuration of low-cost equipment is 1 shaft furnace, 2 oxidation furnaces, and 2 reduction furnaces; heavy oil is used as fuel, and the gas of the shaft furnace is controlled to be reduction The gas in the reduction furnace is reducing, and the gas in the oxidation furnace is oxidizing. The shaft furnace dust enters the reduction furnace through its insulation pipe and high-temperature blower; the reduction furnace smoke enters the bottom of the shaft furnace through its insulation pipe and high-temperature blower, and partly Enter the matching oxidation furnace; the dust from the oxidation furnace passes through its insulation pipe, enters the main pipe of smoke and dust, and then discharges up to the standard; The high-temperature soot flowing through the soot main pipe heats the air pipe and the nitrogen gas pipe of the air separation respectively, and the pre...

Embodiment 2

[0017] The raw material is scrap copper with a Cu content of 72.8wt% and sub-crude copper smelted from scrap copper; the fuel is natural gas; dry oxygen-enriched gas with 85% oxygen is connected to the top blowing of the uniform injector, the temperature of the circulating high-temperature gas flow is 1360°C, and the temperature of the heat preservation chute is The reducing gas is at 1250°C; the others are the same as in Example 1; the above-mentioned low-cost equipment can normally smelt high-quality anode plates with an average copper content of 99.20wt%. After statistics of natural gas consumption, the average index converted into standard coal is 61.9kg standard coal / t anode plate.

Embodiment 3

[0019] The raw material is scrap copper with a Cu content of 88.3wt% and sub-crude copper smelted from scrap copper; the fuel is natural gas; dry oxygen-enriched gas with 75% oxygen is connected to the top blowing and side blowing of the uniform injector, and the temperature of the circulating high-temperature gas flow is 1340 ° C, The reducing gas in the heat preservation chute is at 1240°C; the others are the same as in Example 1; the above-mentioned low-cost equipment can normally smelt high-quality anode plates, with an average copper content of 99.26wt%. After statistics of natural gas consumption, the average index converted into standard coal is 56.1kg standard coal / t anode plate.

Abstract

The invention belongs to the technical field of copper processing, and provides a method for energy conservation of low-cost equipment for smelting of a high-quality anode plate from low-grade copper. A piece of existing technical equipment including a shaft furnace cannot perform smelting on the low-grade copper. According to the method, a shaft furnace burner is controlled to form a high-temperature circulating gas flow, the temperature of the high-temperature circulating gas flow is controlled, temperature of heat-preservation chutes is increased, and gas properties, smoke flowing manners and flowing manners of copper smelting liquid in a shaft furnace, oxidizing furnaces and reduction furnaces are controlled, so that the low-cost equipment adopting low-grade copper material can smelt copper into the high-quality anode plate in a continuous energy-saving manner, and pressure on the technology for electrolysis of the anode plate and cost for electrolysis of the anode plate are reduced.

Description

technical field [0001] The invention relates to the technical field of copper processing, and is an energy-saving method for low-cost equipment for low-grade copper smelting and high-quality anode plates. Background technique [0002] Over the past two decades, copper processing has grown at a double-digit rate in my country every year, and copper processing products have played an increasingly important role in my country's national economy and high-tech fields. However, the development of my country's copper processing industry is limited by the shortage of high-purity copper raw materials. Smelting qualified high-purity anode plates from a large amount of scrap copper has become the key to overcome the development bottleneck. The existing main equipment for smelting anode plates is a reverberatory furnace, but the temperature of the flue dust at the outlet of the reverberatory furnace is about 1200°C, and more than 40% of the energy used for smelting the anode plate in th...
