Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is explained in further detail the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
On the contrary, the utility model cover it is any be defined by the claims do in the spirit and scope of the utility model
Substitution, modification, equivalent method and scheme.Further, right below in order to make the public have a better understanding the utility model
It is detailed to describe some specific detail sections in the datail description of the utility model.Do not have for a person skilled in the art
The utility model can also be understood completely in the description of these detail sections.
For in the prior art, the aggressivity problem of slag lining is able to solve without good technical solution.The application
Inventor has studied stopper slag lining erosion process, finds other than the chemical erosion between molten steel slag and stopper, more
It is main to corrode the inside for entering stopper by the apparent pore on stopper slag line surface from molten steel and slag, it causes inside stopper
Oxidative exfoliation and the physical erosion formed.Carrying out impregnation to stopper can be effectively reduced the apparent porosity of material, reduce plug
The apparent pore on stick surface, reduces molten steel and slag enters the channel inside stopper, alleviates the generation of physical erosion peeling, thus
Improve the corrosion resistance of stopper.But the prior art is big, at high cost to stopper mass-impregnation difficulty, and only soaks to slag lining
Stain is not easy to realize in technique.
The utility model provides a kind of embodiment of plug-in functional block formula stopper；As shown in Fig. 2, including integral type stopper sheet
