Description
Technical field
The utility model belongs to a kind of alloy firing equipment, is to be used for steelmaking process ferroalloy to be heated and dry oven.
Background technology
In steel smelting procedure, because the needs of smelting process and smelting steel grades need add ferroalloy in molten steel, the ferroalloy that adds requires at 400-600 ℃ usually.The heating ferroalloy adopts shaft furnace formula heating furnace more at present, and ferroalloy is filled in burner hearth, and the install combustion device heats the ferroalloy in the stove on the furnace wall.Because the granularity of ferroalloy material piece is less, cause the oven stove internal porosity of filling behind the ferroalloy very low, flue gas can't be effectively mobile, and temperature distributing disproportionation is even, and the efficiency of heating surface is low, and cured effect is poor, and the ferroalloy temperature does not reach the requirement of smelting process.Burner on the furnace wall directly heats ferroalloy in the stove with flame simultaneously, the ferroalloy at burner nozzle place very easily be subjected to the localized hyperthermia that flame gathers and melt, adhesion, and the ferroalloy after the fusing, adhesion can aggravate the localized hyperthermia at spout place, causes body of heater, furnace wall often to be burnt out.
Summary of the invention
The purpose of this utility model provides the bakeout oven for ferro-alloy of a kind of dependable performance, homogeneous heating, the saving energy.
Order of the present utility model can adopt following technical scheme to realize: bakeout oven for ferro-alloy is made up of body of heater, midfeather, burner, bell, discharge valve.Body of heater is square, its top is provided with the body of heater flue of symmetric arrangement, the baking vessel of two symmetries about midfeather being set in the middle of the body of heater body of heater internal furnace being divided into, baking vessel top is communicated with burner hearth, charging aperture is arranged on the top of burner hearth, it is provided with the bell that can open, and the bottom of two baking vessel is provided with discharging opening respectively, and discharging opening is arranged with discharge valve.Two walls of midfeather are symmetrical arranged downward-sloping heating chute, the inside of midfeather is provided with horizontal heating road (a plurality of) and vertical heating road (many groups), each laterally vertically heats and is communicated with one group respectively in heating road, each end that laterally heats the road is provided with the combustion chamber, the place, combustion chamber is provided with burner, one end of heating chute is communicated with vertical heating road, and the other end is communicated with baking vessel.Midfeather over against the furnace wall on downward-sloping smoke evacuation chute and furnace wall flue are set, the furnace wall flue is communicated with the body of heater flue, smoke evacuation chute one end is communicated with the furnace wall flue, the other end is communicated with baking vessel.
During work ferroalloy is joined two baking vessel in the stove by charging aperture, and sealing bell, the ignition combustion device, the flame of burner ejection is in the combustion chamber internal combustion, the high-temperature flue gas that burning produces disperses to enter vertical heating road again after entering horizontal heating road, finally enter two baking vessel respectively by the heating chute that is distributed in the midfeather both sides, the flue gas lateral penetration ferroalloy that enters baking vessel enters the smoke evacuation chute and is discharged out of the furnace by the body of heater flue through the furnace wall flue, finishes heating process.The ferroalloy that heats is discharged through the bottom discharge valve.The heating chute is distributed on the whole midfeather, midfeather over against furnace wall on also be a mass of the smoke evacuation chute, midfeather and midfeather over against furnace wall between distance relative less, flue gas evenly passes ferroalloy with lower resistance like this, guarantee the uniformity of heating, also reduced the consumption of fuel simultaneously.The flame of burner combustion does not enter baking vessel in the combustion chamber internal combustion, prevents that ferroalloy is subjected to localized hyperthermia and melts, and prevents that body of heater, furnace wall from being burnt out.
