Abstract
The utility model discloses a kind of ESP production lines continuous casting tundish stopper screw mandrel protecting device, belongs to steel-smelting device, it is characterised in that：In cylindrical tube structure, cylinder upper end is provided with outward flange to main part, and tube structure lower end is provided with inward flange, and wherein tube structure segment outer radius are equal to the diameter in pouring basket lid stopper hole, and the lower port diameter that lower end inward flange is surrounded is equal to stopper diameter；This device mid portion is steel construction, is wrapped up using ceramic fiber blanket inside and outside steel construction；The ceramic fibre for being located at bottom smears High temperature Refractory Mortar；The position that this device is contacted with stopper is provided with ceramic fibre sealing ring.There is the characteristics of avoiding stopper by high temperature failure compared with prior art.
Description
Technical field
This utility model is related to a kind of steel-smelting device, particularly a kind of preventer suitable for protecting stopper.
Background technology
Continuous casting is that ESP produces one of important ingredient during that, stopper be critical component in casting process it
One.During continuous casting production long-time connects and pours, stopper screw rod is with stopper connecting portion under the high-temperature baking of Metal in Tundish
Yielding thawing causes stopper out of control, and so as to cause, continuous casting is unplanned to stop cast.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, there is provided in a kind of ESP production lines continuous casting
Between bag stopper screw rod preventer.
The technical scheme in the invention for solving the technical problem is：A kind of ESP production lines continuous casting tundish stopper screw mandrel
Preventer, it is characterised in that：Main part is in cylindrical tube structure, and cylinder upper end is provided with outward flange, tube structure lower end
Inward flange is provided with, wherein tube structure segment outer radius are equal to the diameter in pouring basket lid stopper hole, the lower mouth that lower end inward flange is surrounded
Diameter is equal to stopper diameter；This device mid portion is steel construction, is wrapped up using ceramic fiber blanket inside and outside steel construction；It is located at
The ceramic fibre of bottom smears High temperature Refractory Mortar；The position that this device is contacted with stopper is provided with ceramic fibre sealing ring.
There is beneficial effect following prominent：
1st, high temperature damage to stopper can be reduced；
2nd, it is capable of the thermal loss of molten steel；
3rd, the non-programmed halt that because stopper out of control cause can be reduced, so as to reduce the loss that non-programmed halt brings.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is further illustrated with reference to specification drawings and specific embodiments.
As shown in figure 1, this utility model main part is in cylindrical tube structure 2,2 upper end of cylinder is provided with outward flange 1, cylinder
2 lower end of body structure is provided with inward flange 3, and wherein 2 segment outer radius of tube structure are equal to the diameter in pouring basket lid stopper hole, lower end convex
4 diameter of lower mouth that edge 3 is surrounded is equal to stopper diameter.
This device mid portion is the thick steel constructions of 1.5mm, plays a supportive role, inside and outside steel construction using thickness is
The ceramic fiber blanket parcel of 10mm.The ceramic fibre for being located at bottom smears High temperature Refractory Mortar, prevents ceramic fibre from coming off.This dress
Put the position contacted with stopper and be provided with ceramic fibre sealing ring, such that it is able to entirely prevent Metal in Tundish to be baked to stopper silk
Bar.
Main part is put in tundish cap bore during use, ridden in tundish cap bore surrounding by outward flange 1, will plug
Rod is injected in the interstitial hole of this device, plays function of heat insulation by this device, can either avoid stopper by high temperature failure, and
The heat that molten steel can be reduced scatters and disappears, while decreasing the non-programmed halt caused because stopper is out of control, reduces unplanned stopping
The loss that machine brings.
It should be noted that particular of the present utility model has been described in detail to this utility model,
For a person skilled in the art, in the case of without departing substantially from spirit and scope of the present utility model to it carry out various
Obviously change all within protection domain of the present utility model.
