In metallurgical steelmaking technical field, continuous casting machine revolving platform is used for delivering ladle, and ladle is supported to carry out cast work
Industry needs the ladle for being in blank state on continuous casting machine revolving platform being positioned over first-class when conticaster maintenance down
Wait for operation, these are positioned over waits for the ladle of operation to be referred to as offline ladle on the ground.The size of offline ladle temperature drop gives birth to continuous casting
Control, Tapping Temperature of Bof, the Converter condition quality etc. of production process temperature have considerable influence, therefore reduce offline steel
The temperature losses of the process of packet is to ensure production direct motion and the premise that product quality is stablized.By to the vacant temperature drop of the offline ladle of steel mill
Situation statistics is found：Offline ladle average temperature drop per minute under blank state is 1.75 DEG C at present.Currently, to offline in industry
The control of ladle temperature drop, there are mainly two types of modes, and one is raising Tapping Temperature of Bof, but this mode can be to the stove of converter
Condition, steel quality, iron and steel stock cost etc. bring adverse effect；Another kind be by offline ladle be put into refining furnace heating, but this
Kind mode can not only increase refining power consumption and electrode cost, increase enterprise and produce and use cost, and can reduce making for ladle
Use the service life.Thus there is an urgent need for finding, a kind of not only simple in structure, easy for operation, production and application is at low cost while but also can effectively drop
The device of low offline ladle temperature drop.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple in structure, easy for operation, produce and use it is at low cost while again
The steel ladle cover of offline ladle temperature drop can effectively be reduced.
To achieve the above object, the utility model uses following technical solution：Described one kind is for reducing offline steel
The steel ladle cover of packet temperature drop includes inner hollow and size and offline ladle made of being enclosed by upper plate, lower plate and side plate
The compatible backpack cover ontology of ladle mouth is filled with thermal insulation medium, on the outer circle wall of backpack cover ontology in the inside of backpack cover ontology
It is circumferentially arranged have it is several to make this physical efficiency of backpack cover accurately cover the support positioning plates on the ladle mouth of offline ladle, in backpack cover
It is provided with the lifting lug for lifting at the top of ontology, the bottom of backpack cover ontology is provided with one layer of flame retardant coating.
Further, a kind of steel ladle cover for reducing offline ladle temperature drop above-mentioned, wherein：Support positioning plates are distributed in
On the outer circle wall of backpack cover ontology.
Further, a kind of steel ladle cover for reducing offline ladle temperature drop above-mentioned, wherein：The two of support positioning plates
Side is respectively arranged with that support positioning plates and backpack cover ontology is connected firmly first is made to reinforce gusset.
Further, a kind of steel ladle cover for reducing offline ladle temperature drop above-mentioned, wherein：Distinguish in the both sides of lifting lug
It is provided with that lifting lug and backpack cover ontology is connected firmly second is made to reinforce gusset.
Further, a kind of steel ladle cover for reducing offline ladle temperature drop above-mentioned, wherein：In the inside of backpack cover ontology
It is evenly equipped with several making thermal insulation medium adhere better to the anchoring piece on backpack cover body interior side wall.
Further, a kind of steel ladle cover for reducing offline ladle temperature drop above-mentioned, wherein：It is set in the bottom of flame retardant coating
It is equipped with circle sealing bound edge, when backpack cover body cap is on the ladle mouth of offline ladle, just sealing compresses sealing bound edge downwards
On the ladle mouth upper surface of offline ladle.
Through the implementation of the above technical solution, the utility model has the beneficial effects that：Simple in structure, easy for operation,
Produce and use temperature drop that is at low cost while can effectively reducing offline ladle again, the temperature drop of offline ladle by original 1.75 DEG C/
Min is reduced to 0.31 DEG C/min.

Fig. 2 is the structural schematic diagram of the overlook direction of Fig. 1.
Fig. 3 is the structural schematic diagram of A-A sections shown in Fig. 2.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of steel ladle cover for reducing offline ladle temperature drop, including by upper plate
1, inner hollow and size backpack cover ontology compatible with the ladle mouth of offline ladle made of lower plate 2 and side plate 3 enclose,
The inside of backpack cover ontology is filled with thermal insulation medium 4, is circumferentially provided in the outer circle wall upper edge of backpack cover ontology several making packet
It covers this physical efficiency and accurately covers the support positioning plates 5 on the ladle mouth of offline ladle, be provided with and be used at the top of backpack cover ontology
The lifting lug 6 hung is provided with one layer of flame retardant coating 7 in the bottom of backpack cover ontology；In the present embodiment, support positioning plates 5 are distributed in packet
On the outer circle wall of lid ontology；In the present embodiment, it is respectively arranged with to make support positioning plates in the both sides of support positioning plates 5
