Technical field:
The present invention relates to a kind of uniformly heated baking system, particularly to the alloy baking system in a kind of smelting iron and steel technical process.
Background technology:
Alloy is important raw and processed materials required in process for making, moisture in alloy directly affects quality and the tapping temperature of molten steel, re-use after alloy material baking, on the one hand the effect of baking is to remove moisture content, reduce [H] in molten steel, on the other hand can reduce and add the temperature drop of molten steel during molten steel, avoid increasing energy consumption, the most in recent years, alloy baking technique has obtained the most universal application in the smelting process of steel, and raising steel product quality, reduction smelting cost are played an important role by this measure.This just requires that the alloy feed bin adding alloy possesses the function of alloy baking.Existing frequently-used alloy baking device is the most relatively backward, the general employing telescopic burner of combustion gas, the bottom perforate of alloy feed bin be placed in alloy feed bin, utilize thermal-flame direct baking alloy.Such apparatus for baking causes the defects such as the alloy temperature difference is big, it is uneven to toast, and gas-fired is insufficient, and environmental pollution is serious in alloy feed bin, and easily occurs flame-out, introduces the potential safety hazard of gas leakage.If the use severe toxicity gas such as coal gas of converter, blast furnace gas is combustion medium, safety problem just seems to be still prominent, the more important thing is, due to flame direct baking alloy, alloy material is heated uneven, and the temperature difference is big, flame periphery alloy material easily melts caking, cause blanking not smooth, and can not effectively heat away from flame alloy material farther out, therefore can not effectively remove moisture content therein.
Summary of the invention:
The technical problem to be solved is to provide a kind of alloy baking system, including alloy baking feed bin, characterized by further comprising the air stove of band burner assembly, the air distribution device being connected with air stove, the air-supply arrangement being connected with air distribution device, and the annular radiator being placed in alloy baking feed bin being connected with air-supply arrangement.
The present invention further technology is characterized in that
Described burner assembly includes lighter, the burner body of band stable flame pan, the fuel gas inlet being positioned on burner body and combustion air inlet, and flame monitoring equipment.
Described air distribution device agent structure is mixed wind tank, and mixed wind tank is provided with high-temperature gas entrance and normal temperature air entrance, is provided with and makes cold and hot gas mixed uniformly spiral type gas passage in mixed wind tank.
Described air-supply arrangement is high-temperature blower and air supply duct.
Annular fin that described annular radiator includes band pore and the fin of band pore being positioned in annular fin.
Described annular fin is that helical form is arranged.
nullThe invention has the beneficial effects as follows: owing to heretofore described burner assembly includes lighter、Burner body with stable flame pan、The fuel gas inlet being positioned on burner body and combustion air inlet，And flame monitoring equipment，Therefore the oxygen-excess combustion of fuel gas can be realized，Produce 800 ~ 1000 DEG C of high-temperature flue gas，Additionally，Wind tank is i.e. mixed owing to the present invention is additionally provided with air distribution device，High-temperature flue gas can be made to mix with normal temperature air，Reach the temperature 550 ~ 650 DEG C of default baking high-temperature flue gas，The present invention uses air-supply arrangement i.e. high-temperature blower and air supply duct，550 ~ 650 DEG C of high-temperature flue gas are introduced the annular radiator in alloy baking feed bin with the pressure of 3000 ~ 5000Pa，The alloy being distributed in around annular radiator is toasted，So high-temperature flue gas flows through the gap between bulk alloy by circulation radiating device，Add thermalloy，Alloy can be made uniformly to reach default baking temperature 300 ~ 350 DEG C，Can effectively remove the free water in alloy and water of crystallization.And use the present invention that the reduction of the lifting of steel quality in smelting iron and steel technique, steel-making energy consumption is all had more significantly effect; the combustion gas that this alloy baking system is used can be the low-heat value gas such as the coal gas of converter of steel mill, blast furnace gas; can also be the high heating value gases such as coke-stove gas or other combustion gas; the present invention is used not only to achieve maximally utilizing of the energy; and effectively inhibit and produce the generation of NOx in flue gas, this also has greater significance to environmental conservation.
