Abstract
The utility model relates to a triangular hearth structure of an ore furnace, characterized in that the cross section of the hearth is triangular. The triangular hearth structure of an ore furnace has reduced hearth area, shortened furnace-pounding radius and few blind areas and blind points.
Description
Technical field
The utility model relates to the chamber structure of the hot stove in a kind of ore deposit.
Background technology
The hot stove in ore deposit is the ore reduction stove of ferroalloy smelting.The ferroalloy kind of smelting with this device mainly contains ferrosilicon, calcium-silicon, silicomangan, silicomangan, silicochromium etc.Use the basic procedure of smelting iron alloy in ore roaster to be: in packing the furnace charge that mixes into stove from fire door, electrode is embedded in the furnace charge, the resistance heat that relies on electric arc and electric current to produce by furnace charge heats and melts.Molten metal and slag are collected at 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 that the hot stove user in vast ore deposit faces.
The hot stove in ore deposit now adopts spherical hearth mostly.Continuous progress along with The ferroalloy industry entry criteria and development of productivity and metallurgical technology, high grade ore is fewer and feweri, the carbon system of doing reducing agent in the silicon smelting process and the raw-material charcoal of ventilating agent, oneself is through all being replaced by coal, oil coke and cavings, impel the big capacity of equipment choosing, the large electrode of existing burner hearth, brought up big spherical hearth and made that furnace charge increases, area increases; Smash and be jealous of radius to extend, smash furnace apparatus and charging (feeding) equipment increase, reinforced not meticulous not in place, it is not thorough to smash stove, blind area and blind spot have occurred, the crucible district is dwindled, production cost increases, and the furnace charge reduction is not thorough, and electrode can not go deep in the stove, bottom temperature reduces, three-phase is not smooth in the stove, and metal flows out difficulty in the stove, and working of a furnace operation worsens.Though generally adopted rotary burner hearth afterwards, it is strict to raw material, can't satisfy fine fodder and go into stove, and furnace charge large tracts of land caking, the loosening property variation of furnace charge, 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 the stove, and bottom temperature reduces, and three-phase is not smooth in the stove, and working of a furnace operation worsens.
The utility model content
The utility model aims to provide a kind of burner hearth area and dwindles, smashes the ore deposit hot stove triangle burner hearth that the stove radius shortened, was not prone to blind area and blind spot.
The technical scheme that the utility model adopted is: the triangle chamber structure of the hot stove in ore deposit is characterized in that: the burner hearth cross section is a triangle.
Described burner hearth cross section is an equilateral triangle.
The beneficial effects of the utility model are: big charge level district is smaller in the body of heater, not dead material district.Smash stove, reinforced radius weak point, it is thorough to smash stove, the blind area can not occur.
Description of drawings
Accompanying drawing is that the triangle chamber structure of the hot stove in the utility model ore deposit is overlooked the cross-sectional structure schematic diagram.
The specific embodiment
As shown in drawings, the triangle chamber structure of the hot stove in a kind of ore deposit of the utility model is provided with electrode 2 and crucible layer 3 in body of heater 1, and electrode 2 symmetries are installed in the body of heater 1, and crucible layer 3 is located at body of heater 1 inboard; Burner hearth 4 cross sections in the body of heater 1 are equilateral triangle, and electrode 2 symmetries are installed in the equilateral triangle burner hearth 4.
Simple in structure, compact, the advantages such as investment is little, easy care that the utility model chamber structure possesses, littler than equal big or small typical circular burner hearth because of burner hearth 4 cross-sectional areas, smash the stove radius and shorten, smash furnace apparatus and charging (feeding) equipment dwindles, feeding in raw material can be meticulousr, it is more thorough to smash stove, blind area and blind spot, the increase of crucible district can not occur, furnace charge is reduced better.
Claims (2)
1. the triangle chamber structure of the hot stove in ore deposit, it is characterized in that: the burner hearth cross section is a triangle.
2. according to the triangle chamber structure of the hot stove in the described ore deposit of claim 1; It is characterized in that: described burner hearth cross section is an equilateral triangle.
