Abstract
The utility model discloses a double-furnace double-side blowing slag forming and top blowing copper making continuous converting furnace. The double-furnace double-side blowing slag forming and top blowing copper making continuous converting furnace respectively performs blowing processes in a slag forming period and a copper making period in a PS (Pierce-Smith) converter sequentially, and are performed in two blowing spaces so as to realize continuous blowing processes including continuous copper matte feeding, continuous air blowing, continuous slag forming, continuous slag discharge and continuous or intermittent crude copper discharge; simultaneously, single-side blowing of the converter is changed to double-side blowing and top blowing, so that the scouring of furnace bricks caused by splashing of a melt can be reduced from the structure of a furnace body, and the service life of the furnace bricks can be prolonged; furthermore, a flux can be added into the melt from the furnace top, oxygen-rich air blown from double sides is in direct contact with the melt, the utilization rate of the oxygen-rich air is higher than that of top blowing, so that the flux can be in more uniform contact with the melt more rapidly; therefore, the production and precipitation of a large amount of magnetic iron during the blowing process can be inhibited more effectively.
Description
Technical field the present invention relates to blister copper converting furnace, is specifically related to a kind of twin furnace bilateral that extracts continuously blister copper for matte pyrogenic process and blows slag making top blast and make copper continuous-blowing furnace.
Background technology blows in the production of blister copper at 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 the shortcomings such as idle power consumption is high, the refractory materials rate of recovery short and sulphur in work-ing life 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 top blast continuous converting of Er Shi Mitsubishi.After flash blowing is the matte shrend that melting is produced, grinds to form fine powder and dry again, together with ground flux one, reinstate high-pressure blast 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 slag cupric is high, direct yield is low, production cost is high blows.Mitsubishi Continuous converting process is hot matte to be flowed directly into converting furnace by chute and simultaneously to spraying into solvent in melt and oxygen-rich air blows; Although energy consumption is lower, existence blowing slag cupric is high, direct yield is low, blister copper sulphur-containing difficult-to is controlled, the calcium scum shortcoming serious to refractory corrosion.
Summary of the invention object of the present invention is exactly the deficiency existing 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 slag cupric, improves the blister copper continuous-blowing furnace of direct yield.
The object of the invention is to be achieved through the following technical solutions:
A kind of twin furnace bilateral blows slag making top blast and makes copper continuous-blowing furnace, comprise slag making stove and make copper stove, be arranged on slag making stove and the solvent charging opening of making copper stove furnace roof, slag making stove and making on copper stove for discharging the slag-drip opening of blowing slag, on slag making stove for discharging the white metal discharge outlet of white metal, make on copper stove for discharging the blister copper discharge outlet of blister copper, slag making stove and making on copper stove for discharging the smoke outlet of flue gas, the cold burden of making on copper stove adds entrance, slag making stove porthole, make copper stove porthole, slag making stove safety mouthful, make copper stove safety mouthful, be arranged on the ventilation hole on slag making stove furnace wall body and make lance tube insert port and the lance tube at copper furnace body top, ventilation hole on described furnace wall body for being blown into continuously oxygen-rich air in the body of heater of slag making stove, lance tube is inserted in described lance tube insert port, for being blown into continuously oxygen-rich air to making in the body of heater of copper stove.
Edge tuyere in ventilation hole on described slag making furnace wall body, the threeway of the tuyere external flange eye of wind, control valve, branch wind pipe, blast main form complete slag making stove oxygen system and blast oxygen-rich air in stoves.
Described solvent is siliceous solvent and limestone flux.
The invention has the advantages that: 1, adopt twin furnace bilateral to blow slag making top blast and make copper continuous-blowing furnace, by the slag forming period of successively carrying out in PS converter and copper making period converting process, split two blowing and carry out in spaces, thereby realize entering continuously matte, continuous blast, slag making continuously, slagging 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 is separated with white matte, and this slag peroxidation phenomenon is lighter, Fe wherein
3o
4content is inevitable lower, and the Red copper oxide wherein dissolving 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 copper stove, its Grade Control is between 75-76%, and iron-holder is wherein 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 is 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 is wherein 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 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 converter one-sided to blow and change that bilateral blows and top blast into, so both can from furnace binding realization alleviate melt splash to stove brick wash away, extend stove brick work-ing life, can realize flux is added to melt from furnace roof again; 3, with respect to application number, be the twin furnace multiple gun top blast continuous-blowing furnace of " 2013102430851 ", the mode that slag making stove adopts bilateral to blow oxygen enrichment, tuyere is directly embedded in melt, blow and fuse the mixolimnion of slag and matte, and in twin furnace multiple gun top blast continuous-blowing furnace, slag making stove adopts that top-submerged lance blows, it is slag blanket, bilateral blows oxygen-rich air and directly contacts with melt, oxygen-rich air utilization ratio is higher than top blast, 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; Adopt top-blown spray gun to change frequent, cost is higher.
