Description
Technical Field
The utility model belongs to the technical field of ferrous metallurgy, concretely relates to novel ladle shroud.
Background
In the continuous casting production process, because the ladle is filled with high-temperature molten steel with the temperature of more than 1500 ℃, different molten steel has own liquidus temperature (at which the molten steel begins to solidify). In the casting process, if the temperature is lower, the tundish can be frozen, so that the heat preservation work of the molten steel in the ladle needs to be performed. The ladle upper mouth is usually open and covered with a ladle lid to reduce process temperature drop.
In the continuous casting production at present, a ladle cover of a steel ladle is mainly filled with refractory castable, and the ladle cover is heavy and has poor heat insulation effect; the process can be regarded as solid heat transfer because the full casting material is filled, so that the thermal deformation is serious in the using process, and the service life of the ladle cover is greatly shortened; and the binding property between the refractory castable and the ladle shell is not high, and the refractory castable is easy to fall off.
Disclosure of Invention
An object of the utility model is to overcome the not enough of technique, provide a novel ladle be built by contract, it is lighter to have a weight, and it is effectual to keep warm, and life is longer, pouring material and the advantage that the associativity is high between the cladding, is difficult for droing.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a novel ladle be built by contract, includes the built by contract shell, and the built by contract shell still includes fluke, rock wool layer and castable layer for former ladle be built by contract shell, the fluke is evenly fixed at the bottom surface in the built by contract shell, the rock wool layer is packed in the built by contract shell inboard, the castable layer is at rock wool layer upper surface packing.
Preferably, the anchor flukes are uniformly distributed on the inner bottom surface of the covering shell, so that the coverage area of the anchor flukes is increased, and the holding power of the anchor flukes is improved.
Preferably, the fluke opening faces upwards, so that the fluke opening end can contact the castable layer, and adhesion between the fluke opening end and the castable layer is increased.
Preferably, the length of the fluke is larger than the height of the rock wool layer, and the fluke can penetrate through the rock wool layer sufficiently, so that the opening of the fluke is in contact with the castable layer.
Preferably, the height of the rock wool layer is lower than that of the outer wall of the ladle cover shell, and a filling space is reserved for the castable layer.
Specifically, the rock wool layer density is lower than the material density of the castable layer, so that the weight of the whole ladle cover is reduced, and the use is convenient.
Specifically, the inner space of the covering shell is completely filled, and the overall height is consistent with the height of the outer wall of the covering shell. The heat preservation effect is best, and the protection of the ladle cover and the prevention of the falling of the rock wool layer are further realized.
Specifically, the utility model discloses a rock wool layer is filled between the be built by contract shell and the pouring bed of material, insulates against heat and keeps warm, changes the solid and gaseous heat transfer into with full solid heat transfer, reduces heat transfer efficiency in order to overcome former be built by contract shell defect that the effect is not good that keeps warm. Rock wool layer density is little than pouring bed of material density, adopts rock wool layer to fill the middle part and can reduce the whole weight of be built by contract, facilitates the use. The fluke evenly is covered all over ladle and covers the shell internal surface, and fluke opening part contacts with the pouring material layer, can guarantee the effective combination of pouring material layer and ladle and cover shell for the pouring material layer is difficult for droing with the rock wool layer, thereby prolongs the life of ladle and cover.
Through the technical scheme, the utility model discloses can reduce the heat transfer efficiency of be built by contract shell, improve the heat preservation effect, reduce the whole weight of be built by contract, facilitate the use can guarantee the effective combination of the pouring bed of material and be built by contract shell moreover for the pouring bed of material and rock wool layer are difficult for droing, thereby increase of service life.

Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As described in connection with fig. 1-2.
As shown in the figure, a novel ladle cover comprises a cover shell 1, wherein the cover shell 1 is an original ladle cover shell and further comprises flukes 2, rock wool layers 3 and a pouring material layer 4, the flukes 2 are fixed on the inner bottom surface of the cover shell 1, the rock wool layers 3 are filled on the inner surface of the cover shell 1, and the pouring material layer 4 is poured on the upper surface of the rock wool layers 3.
