The technological process of production of ladle is：Converter (or electric furnace) connects steel-refine-pour steel-hot repair-and waits steel waiting,
It is very high to the temperature requirement of ladle in this technological process.Ladle baking facility is the equipment heated to ladle, its work
Efficiency directly influences the temperature of ladle, influences the flow and product quality entirely made steel indirectly, while influences that steel mill is energy saving to be subtracted
The demand of row.So finding a kind of method, the efficiency of combustion of fuel is improved, reduces the discharge of polluted gas, meets production need
Ask, so as to achieve the purpose that energy-saving.
Most of existing backpack cover is all the heat-insulated backpack cover of individual layer, is primarily present following deficiency：1st, ladle is not made full use of
The preheating of baking, thermal loss are very big；2nd, backpack cover weight is larger, increases facility load；3rd, preheating can not reuse, to fire resisting
Material causes expensive damage, it is necessary to often repair；4th, it is necessary to wind turbine air feed in the baking of other burners.Some backpacks cover are with porous
Ceramic material does heat storage, and porous ceramics heat storage can put aside certain heat, but this mechanical strength is relatively low, no
Larger external force and repeated stock can be born, in addition, steel mill's bad environments, be easy to cause the blocking of porous regenerator body.
Therefore, a kind of light-weight, waste heat is designed to recycle, blow and can be combined with structure atomizer without wind turbine
Steel ladle cover is very necessary.
The content of the invention
The purpose of the present invention is to propose to a kind of steel ladle cover suitable for structure atomizer, have light-weight, service life is long,
The characteristics of without wind turbine air-supply and efficiently utilizing waste heat, can preferably meet structure atomizer to the air needed for ladle baking
Amount, and improve the temperature of ladle baking.
The technical scheme is that：
A kind of steel ladle cover suitable for structure atomizer, including lid, reinforce girth sheets, resistance to guncotton, lifting lug, air hole,
Insulating layer, inverted-F suspender member, air preheater, burner reserved opening, partition plate；
The partition plate is arranged in the cavity of lid, and the cavity of lid is divided into upper cavity and lower chamber；
The burner reserved opening passes through the center of lid top plate and the center of partition plate；
The girth sheets of reinforcing is arranged on the lower face of lid；
The resistance to guncotton is arranged on the inner wall of the partition plate lower surface and lower chamber, and the resistance to guncotton passes through the inverted-F
Suspender member is fixed, and partition plate lower surface is fixed in the upper end of the inverted-F suspender member；
The quantity of the lifting lug is at least 4, and all lifting lugs are uniformly fixedly arranged on the outer wall of lid in a ring；
The air hole is opened on lid top plate；
The insulating layer is fixedly arranged on the lower surface of lid top plate；
The air preheater is uniformly fixed in the upper cavity in a ring using the center of lid top plate as the center of circle.
Further, the steel ladle cover further includes fixed plate and bolt, and the fixed plate is arranged on the upper surface of lid top plate,
The bolt passes through fixed plate and lid top plate.
Further, the quantity of the fixed plate is 4, and each fixed plate is equipped with 4 bolts；4 fixed plates are in square
Shape is arranged on the upper surface of the lid top plate, and the diagonal intersection point of the rectangle is overlapped with the center of lid top plate.
Further, the quantity of the air hole is at least 8.
Further, the quantity of the inverted-F suspender member is at least 200.
Further, the resistance to guncotton is aluminosilicate refractory fiber felt.
Further, the insulating layer is slapped together by ceramic fiber module.
Beneficial effects of the present invention are：The backpack cover can the burner with structure atomizer or with bluff body fluidic device mutually tie
Close, ladle is toasted.The backpack cover has the advantages that light-weight, rational in infrastructure low etc. with manufacture cost, not only reduces heat
Scatter and disappear, and improve the temperature of combustion air, so as to improve the temperature of ladle baking.
After testing, heat energy recovery rate more than 70%, thus greatly reduces the discharge temperature of burning waste gas in exhaust gas
Degree, drastically reduce the area the pollution to environment.Baking temperature can be brought up to more than 1100 DEG C at the same time, meet industrial production
Demand.
