Immersed oxygen lance continuous converting inclined metallurgical furnace

Abstract

The invention discloses an immersed oxygen lance continuous converting inclined metallurgical furnace capable of singly performing converting to prepare crude copper and capable of continuously performing converting and refining to prepare anode copper. A flux port is formed in the top end of a furnace body; a hot material port is formed in an end wall, far from one side of a mounting plane, of the furnace body; a cold material port is formed in the upper side, near one side of the mounting plane, of the furnace body; a slag discharge port is formed in the lower side, near one side of the mounting plane, of the furnace body; a copper discharge port is formed in an end wall, near one side of the mounting panel, of the furnace body; a flue port is formed in the top of the furnace body, and multiple oxygen lance insertion holes are formed in the bottom; 1-25 oxygen lances are provided; and gaps of the oxygen lances are 0.5-1.5 m. The immersed oxygen lance continuous converting inclined metallurgical furnace has the following advantages: the metallurgical furnace can prepare both crude copper and anode copper, and is excellent in smelting effect, high in treatment capacity, high in oxygen utilization rate, excellent in environmental protection, excellent in labor conditions, high in automation degree, safe in operation and long service life of the furnace body.

Description

technical field [0001] The invention belongs to the field of nonferrous metallurgy and relates to a continuous blowing metallurgical furnace. Background technique [0002] At present, more than 90% of copper pyrometallurgy in the world today use PS converters in terms of copper blowing process. As far as the copper refining process is concerned, reverberatory furnaces, rotary furnaces, and tilting furnaces are mostly used. Neither of these two smelting processes can be carried out in the same furnace, which has the disadvantages of long smelting cycle, small scale and low efficiency. [0003] At present, there are two continuous blowing processes for industrial production in foreign countries. One is the Mitsubishi method developed by Japan, which uses a top blowing furnace to continuously blow copper matte to blister copper, realizing continuous copper smelting. The Mitsubishi method is a continuous copper smelting process with less investment and lower cost at present; t...

AI Technical Summary

Problems solved by technology

The Mitsubishi method is a continuous copper smelting process with less investment and lower cost at present; the other is the copper smelting process of the Kennecott smelter in Utah, USA, which uses a flash furnace to blow copper matte into blister copper. The environment is more friendly, but it is not a continuous copper smelting process in the true sense, and the process is more complicated

Although the above two processes have solved the environmental protection problems of blowing operations, they both have deficiencies and need to be further improved.
