Abstract
The utility model relates to a funnel-typed alloy heating device, which is especially suitable for block-typed ferroalloys to dry, heat and store in a hot state in metallurgy factories and mines. The utility model can be a collecting bucket below an elevated stockhouse to realize that the ferroalloy of the converter steelmaking is heated online; the utility model can be fallen on earth to form an individual heating device of the ferroalloy, having the advantage of flexible operation. The casing of the utility model is in a funnel shape; a flat and cyclonic burner is installed at the side bottom of the utility model; a porous heat conducting pipe is arranged in the combustion chamber and the lower part of the porous heat conducting pipe is communicated with the combustion chamber. The utility model has the advantages of energy saving, homogeneous heating and simple structure.
Description
The utility model relates to a kind of funneling alloy firing equipment, is specially adapted to the drying of factories and miness such as metallurgy, mine to ferroalloy and other block raw materials, heating and hot storage etc.Have characteristics such as simple structure, applying flexible, the saving energy, homogeneous heating, long service life.
In field of steel-making, because the requirement of smelting process and steel grades needs to add hot ferroalloy in molten steel, the degree of heat of these ferroalloys will directly affect the quality of steel grade and the recovery rate of alloy material thereof.And the quality of the equipment of alloy heating seriously affects the height of steel making working procedure energy consumption.Before the utility model was made, conventional alloy mode of heating had shaft furnace formula, kiln formula etc., though these firing equipment heating efficiencies are bigger, have the heating inequality saturating, waste energy, floor space is big, shortcomings such as equipment manufacturing cost height.In recent years, occurred a kind of hopper formula alloy firing equipment that is applied in the converter again, it is after the ferroalloy in the high hopper is sent into hopper, to heat by the burner that is contained on the bucket cover, this equipment is only applicable in the newly-built pneumatic steelmaking factory, and the scope of application is restricted.Based on above-mentioned situation, the utility model proposes a kind of funneling alloy firing equipment, not only the scope of application is wide for it, heats effectively, and saves the energy, can realize automatic control.
The purpose of this utility model is will seek that a kind of dependable performance, the scope of application are wide, homogeneous heating, the saving energy, can realize the automatic alloy firing equipment of controlling.
Funneling alloy firing equipment of the present utility model carries out pilot production in Anshan iron and steel plant factory, it uses the result to show: with this equipment heating ferroalloy, more than shaft furnace formula that its firing rate is conventional and kiln formula are fast again, save the energy about 45%, on equipment manufacturing cost, can save great amount of investment.
The formation of funneling alloy firing equipment of the present utility model and using method accompanying drawings thereof are as follows, accompanying drawing 1 is the formation situation of funneling alloy firing equipment, this mainly is made up of furnace shell (1), bell (2), burner (3), porous heat transfer tube (4), charge door (5), discharging opening (6), meausring apparatus (7), exhaust apparatus (8) etc., it both can realize the online heating of pneumatic steelmaking with ferroalloy as the bucket that gathers under the high hopper, also can drop on ground and constitute an independent ferroalloy firing equipment, applied range uses flexibly.
Funneling alloy firing equipment of the present utility model, its furnace shell (1) is funnel-form, and shell wall is formed by four layers, and innermost layer is the steel funnel plate, is drilled with uniform heat transfer hole on the plate, and being close to is the combustion chamber layer, is refractory insulating layer then, outermost is the steel plate crust.For preventing the funnel plate compressive deformation that is heated, between funnel plate and refractory insulating layer, support at interval with refractory brick.Burner (3) is contained in the side-lower of furnace shell, and it is up to be convenient to hot gas like this, heats effective.For the flame that makes burner (3) ejection impacts funnel plate within bounds, and spreadability is preferably arranged, burner is selected the flat cyclone-type for use.Consider homogeneous heating degree to alloy material in the stove, not only evenly perforate on funnel plate, and porous heat transfer tube (4) is set in stove, the bottom of pipe communicates with the combustion chamber, by it the combustion of high temperature fire is imported the middle part of stockpile, thereby reach the purpose of even heating.Bell (2) not only can be incubated but also can collect and derive flue gas, improves the thermal efficiency, environment purification.Meausring apparatus (7) is used to control speed and the quantity that adds and give discharging, just because of having adopted flat rotating burner (3) and porous heat transfer tube (4), just can make thermal-flame directly penetrate heated alloy material middle part, and then reach the double effects of saving the energy and homogeneous heating.
Use funneling alloy firing equipment of the present utility model, need earlier alloy material to be placed equipment, refire burner and get final product, but continuous charging and discharging in use, and the big I of flame is controlled by the valve on the gas circuit.
Consider the pollution problem that is heated material, funneling alloy firing equipment of the present utility model adopts gaseous fuel to heat.
Claims (1)
1, a kind of funneling alloy firing equipment, form by furnace shell (1), bell (2), burner (3), porous heat transfer tube (4), charge door (5), discharging opening (6), meausring apparatus (7) etc., it is characterized in that furnace shell (1) is funnel-form, and the furnace shell shell wall constitutes by four layers, be funnel flaggy, combustion chamber layer, insulating refractory layer and steel crust with holes, burner (3) is positioned on the side-lower of furnace shell (1), and is communicated with combustion chamber and porous heat transfer tube (4).
