Abstract
The utility model discloses a double-furnace multi-gun top-blown continuous converting furnace and a continuous crude copper extraction process. According to the double-furnace multi-gun top-blown continuous converting furnace, the converting processes in a slag forming period and a copper making period, which are sequentially performed in a PS converter, are respectively performed into two converting spaces, so that the continuous converting process about continuous copper matte input, continuous blast, continuous slag forming, continuous deslagging, and continuous or incontinuous crude copper discharging is realized, meanwhile, the side blowing mode of the converter is changed into a multi-gun dangling top blowing mode, so that washing to furnace blocks caused by melt spattering is reduced, and the service lives of the furnace blocks are prolonged, and a fusing agent sprayed into melt from a spray gun sleeve is contacted with the melt more uniformly and quickly, and a large amount of magnetic iron produced and separated out during the converting process is effectively restrained.
Description
A kind of blister copper converting furnace of technical field, relate to a kind of twin furnace multiple gun top blast continuous-blowing furnace that extracts continuously blister copper for the matte pyrogenic process.
Background technology blows in the production of blister copper at the matte pyrogenic process, and PS bessemerizes technique and accounts for the overwhelming majority.Along with the development of blister copper pyrogenic process extraction process, traditional PS bessemerizes the requirement that is not suitable for modern environmental protection, causes that idle power consumption is high, the shortcoming such as refractory materials work-ing life is short and rate of recovery sulphur is low, will be eliminated gradually.At present, blister copper continuous converting technique is existing two kinds in the world: the one, and flash continuous converting, the 2nd, Mitsubishi's top blast continuous converting.After the flash blowing is the matte shrend that melting is produced, grinds to form fine powder and dry again, reinstate high-pressure blast together with ground flux one and spray in Flash Smelting Furnace, through peroxidation, carry out slag making, make copper; This technique exists can not digest cold burden, comprehensive energy consumption is high, the shortcoming that the slag cupric is high, direct yield is low, production cost is high blows.The Mitsubishi Continuous converting process is hot matte to be flowed directly into to converting furnace by chute and simultaneously to spraying into solvent in melt and oxygen-rich air is blown; Although energy consumption is lower, existence blowing slag cupric is high, direct yield is low, the blister copper sulphur-containing difficult-to is controlled, the calcium scum shortcoming serious to refractory corrosion.
Summary of the invention purpose of the present invention is exactly the deficiency existed for above-mentioned prior art, and a kind of effective minimizing harmful smoke is provided, and reduces reactive power consumption, extends refractory materials work-ing life, reduces the slag cupric, improves the blister copper continuous-blowing furnace of direct yield.
The objective of the invention is to be achieved through the following technical solutions:
A kind of twin furnace multiple gun top blast continuous-blowing furnace, comprise the slag making stove and make the copper stove, charging opening, for the slag-drip opening that discharges the blowing slag, for the white metal discharge outlet of discharging white metal, for discharging the blister copper discharge outlet of blister copper, for the smoke outlet of discharging flue gas and lance tube insert port and the lance tube that is arranged on the body of heater top, described lance tube is inserted in described lance tube insert port, for to the slag making stove with make in the body of heater of copper stove and be blown into continuously oxygen-rich air and solvent.
Described solvent is siliceous solvent and limestone flux.
Described lance tube is two-layer, and the liftable rotation.
Described slag making stove and make the copper stove, middlely connect with the white metal chute.
The described copper stove of making is provided with cold burden and adds entrance.
Also comprise the slag making stove safety mouthful being located at respectively the slag making stove, making copper furnace side wall bottom, make copper stove safety mouthful.
The slag making stove and make the body of heater headwall of copper stove and the body of heater side wall by refractory brick and refractory material laying, and with watercooling jacket.
Described watercooling jacket is 3 layers, the two-layer refractory brick in interval in every layer of watercooling jacket.
The invention has the advantages that: 1, adopt twin furnace multiple gun top blast continuous-blowing furnace, the slag forming period that to successively carry out in the PS converter and copper making period converting process, split two blowing and carry out in spaces, thereby realize advancing continuously matte, continuous blast, slag making continuously, slag tap continuously, continuously or be interrupted the continuous converting process of emitting blister copper.Like this, after slag forming period completes, i.e. realization blowing slag separates with white matte, and this slag peroxidation phenomenon is lighter, Fe wherein
3o
4content is inevitable lower, and the Red copper oxide wherein dissolved also seldom, adds suitably precipitate and separate, so wherein the copper content of slag can not surpass and bessemerize slag cupric 4%; Enter the white matte of making the copper stove, its Grade Control is between 75-76%, and iron-holder wherein is 3.0% left and right, like this, while making copper, only with the slag of total quantity of slag 13.0%, makes copper, although must there be peroxidation in this part slag when making copper, and Fe wherein
3o
4content also can be higher, but also can dissolve a large amount of cupric oxide, and cupric wherein is inevitable very high, is about 14%-20%; But, because its quantity of slag is less, directly returning to slag forming period thermal equilibrium can meet; So can not affect direct yield.Obviously, this technique both can realize the continuous converting operation, can as converter, realize again lower blowing slag cupric, can also obtain low, the impure few high-quality blister copper of sulfur-bearing; 2, this programme proposes to change the side-blown of converter into many spray guns unsettled top blast, so both can realize alleviating the melt splash from furnace binding the stove brick washed away, extends stove brick work-ing life, can realize again flux is sprayed into to melt from the spray gun sleeve pipe, so that flux and melt are more evenly, promptly contact, thereby more effectively suppress in converting process ferromagnetic a large amount of generations and separate out.
