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, flow process and product quality that remote-effects are entirely made steel, while affecting steel mill's energy-conservation to subtract
The demand of row.So, a kind of method is found, the efficiency of combustion of fuel is improved, the discharge of dusty gass is reduced, production need are met
Ask, so as to reach energy-saving purpose.
Existing clad great majority are all the heat-insulated clads of monolayer, are primarily present following deficiency：1st, ladle is not made full use of
The preheating of baking, thermal loss are very big；2nd, clad weight is larger, increases facility load；3rd, preheating cannot be reused, to fire resisting
Material causes expensive damage, needs Jing often to keep in repair；4th, in other burner bakings, need blower fan air feed.Some clad porous
Ceramic material does heat storage, and porous ceramicss 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, easily cause the blocking of porous regenerator body.
Therefore, design a kind of lightweight, waste heat to recycle, blow without the need for blower fan and can combine with structure atomizer
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, with lightweight, long service life,
The characteristics of without the need for blower fan air-supply and efficient utilization waste heat, structure atomizer can be preferably met 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 Pyroxylin, hanger, air hole,
Heat-insulation layer, inverted-F suspender member, air preheater, burner reserved opening, dividing plate；
The dividing plate is in the cavity of lid, and the cavity of lid is divided into upper cavity and lower chamber；
The center at center and dividing plate of the burner reserved opening through lid top plate；
The girth sheets of reinforcing is on the lower surface of lid；
The resistance to Pyroxylin is located on the inwall of the dividing plate lower surface and lower chamber, and the resistance to Pyroxylin is by the inverted-F
Suspender member is fixed, and dividing plate lower surface is fixed in the upper end of the inverted-F suspender member；
The quantity of the hanger is at least 4, and all hangers are uniformly fixedly arranged on the outer wall of lid in a ring；
The air hole is opened on lid top plate；
The heat-insulation layer is fixedly arranged on the lower surface of lid top plate；
The air preheater is uniformly fixed in the epicoele body in a ring by the center of circle of the center of lid top plate.
Further, the steel ladle cover also includes fixed plate and bolt, and the fixed plate is located at 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 provided with 4 bolts；4 fixed plates are in square
Upper surface of the shape located at the lid top plate, the diagonal intersection point of the rectangle and the center superposition 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 Pyroxylin is aluminosilicate refractory fiber felt.
Further, the heat-insulation layer is slapped together by ceramic fiber module.
Beneficial effects of the present invention are：The clad can be mutually tied with structure atomizer or the burner with bluff body mjector
Close, ladle is toasted.The clad has the advantages that lightweight, rational in infrastructure and low cost of manufacture, 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, in waste gas, heat energy recovery rate, more than 70%, thus greatly reduces the discharge temperature of burning waste gas
Degree, drastically reduce the area the pollution to environment.Baking temperature can be brought up to more than 1100 DEG C simultaneously, meet commercial production
Demand.
