Abstract
The utility model provides a multi-electrode submerged arc furnace which comprises a furnace body and electrodes. The multi-electrode submerged arc furnace is characterized in that the number of the electrodes is smaller than 6, the electrodes are symmetrically installed in a hearth of the furnace body. By the multi-electrode arrangement, the electrode diameter can be decreased, a crucible region is increased, the furnace capacity is effectively increased, large-specification electrodes with high cost are omitted, and power consumption is reduced. By multi-electrode symmetric installation, heat in the hearth is intensive, three phases are unblocked, and the multi-electrode submerged arc furnace is compact in structure.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, is specifically related to a kind of multi-electrode mineral hot furnace.
Background technology
Mineral hot furnace is the ore reduction stove of ferroalloy smelting.By the ferroalloy kind that this device is smelted, mainly contain ferrosilicon, calcium-silicon, silicomangan, silicochromium etc.The basic procedure of smelting iron alloy in ore roaster is: the furnace charge mixing is packed in stove from fire door, electrode is embedded in furnace charge, the resistance heat that relies on electric arc and electric current to produce by furnace charge heats and melts.The can slag melting is gathered in furnace bottom by the tapping hole deslagging that regularly taps a blast furnace, and all production processes are continuous strong endothermic processes.Therefore, the smelting of ferroalloy is the especially big user of power consumption.How shortening the heat, reducing power consumption is the common difficulty facing during vast mineral hot furnace is used.
The mineral hot furnace of cash adopts spherical hearth mostly.Along with the development of the ferroalloy industry entry criteria and productivity and the continuous progress of metallurgical technology, high grade ore is fewer and feweri, in silicon smelting process, make carbonaceous reducing agent and the raw-material charcoal of ventilating agent, all by coal, tar and cavings, replaced, impel the large capacity of equipment choosing, the large electrode of existing burner hearth, caused large spherical hearth to use that furnace charge increases, area increases; Smash stove radius and lengthen, smash furnace apparatus and charging (feeding) equipment increase, reinforced not meticulous not in place, smash stove not thorough, there is blind area and blind spot, crucible district is dwindled, production cost increases, and furnace charge reduction is not thorough, and electrode can not go deep in stove, bottom temperature reduces, in stove, three-phase is not smooth, and in stove, metal flows out difficulty, and working of a furnace operation worsens.Although generally adopted afterwards rotary burner hearth, it requires strict to raw material, cannot meet yellow phosphate, and furnace charge large area caking, the loosening property variation of furnace charge, and gas permeability is poor, and the rotary speed of body of heater reduces, and the accident rate of electrode improves.Electrode can not go deep in stove, and bottom temperature reduces, and in stove, three-phase is not smooth, and working of a furnace operation worsens.
Utility model content
The purpose of this utility model is to propose a kind of multi-electrode mineral hot furnace of avoiding the too high large specification electrode of use cost and reducing power consumption.
The technical solution of the utility model is achieved in that a kind of multi-electrode mineral hot furnace, comprises body of heater and electrode, and the quantity of described electrode is no less than 6 and symmetrical being arranged in the burner hearth of described body of heater.
Adopt Multi-Electrode Arrangement, can dwindle electrode diameter, increase crucible district, effectively expand heat size, avoid the too high large specification electrode of use cost and reduce power consumption.Multi-electrode is symmetrical to be installed and makes that in burner hearth, heat is concentrated, three-phase is unimpeded and compact conformation.
Further, the side inwall of described body of heater and the distance apart between its nearest electrode equate and are positioned at the arc light district of this electrode.Because the side inwall of body of heater equates at a distance of nearest interelectrode distance with it, eliminate blind area, carbide has been controlled in the arc light district of each electrode, stoped carbide to be piled up, eliminate the short circuit current of working end under undesired smelting state, make the stability of working end stronger.
