Abstract
The utility model provides a submerged arc furnace. The submerged arc furnace comprises a furnace body and electrodes, wherein the electrodes are symmetrically installed inside a combustion chamber of the furnace body. The submerged arc furnace is characterized in that distance from the internal walls on the side edges of the furnace to the electrodes which are closest to the internal walls is identical and the distance is arranged inside an arc light zone of the electrode. According to the submerged arc furnace, distance from the internal walls on the side edges of the furnace to the electrodes which are closest to the internal walls is identical, a dead zone is eliminated, carbide is controlled to be in the arc light zone of every electrode, the carbide is prevented from accumulating, short circuit currents of a working end at an abnormal smelting state are eliminated, and the stability of the working end is strong.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, is specifically related to a kind of mineral hot furnace.
Background technology
Mineral hot furnace is the ore reduction stove of ferroalloy smelting.Mainly contain ferrosilicon, calcium-silicon, silicomangan, silicochromium etc. by the ferroalloy kind that this device is smelted.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 timing deslagging that 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, and spherical hearth, in normal productive process, can produce raw material district, grog district, reducing zone.Reducing zone will inevitably first produce carbide, restores.And carbide electric conductivity between 1500~2500 degree is very strong, exceedes 2500 and will reduce while spending.The arc heat temperature of only having electrode to produce exceedes 2500 degree, just can make carbide reduction.Owing to piling up near the carbide in body of heater Bian Siliao district in smelting process, cause electrode to produce short circuit, make electrode do idle power consumption, impel electrode to be difficult to lower inserting, cause furnace inner environment further to worsen, reduce production efficiency.
Utility model content
The purpose of this utility model is to propose a kind of mineral hot furnace of eliminating burner hearth blind area.
The technical solution of the utility model is achieved in that a kind of mineral hot furnace, comprise body of heater and electrode, this electrode symmetry is arranged in the burner hearth of described body of heater, the side inwall of described body of heater and the arc light district that equates and be positioned at this electrode apart from the distance between its nearest 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.
Further, adopt Multi-Electrode Arrangement, dwindle electrode diameter, increase crucible district, effectively expand heat size, avoid the too high large specification electrode of use cost and reduce power consumption.
Further, described sole outer wall is consistent with the shape of inwall, makes the integral thickness of sole equate, can save the manufacturing cost of body of heater and reduce floor space is installed.
