Abstract
The utility model provides a long-life package stopper rod in middle of continuous casting, includes the stopper rod body, the one end of stopper rod body is slick and sly ellipsoid structure, it is equipped with the circumference flange to lie in stopper rod slag line position on the outer circumference of stopper rod body, the overlooking shape of circumference flange is circular, and the side view shape of circumference flange is circular, oval or square. The utility model thickens the slag line part of the stopper rod to form a circumferential flange, so that the stopper rod can bear larger erosion amount than the original stopper rod, and the problem of the service life reduction of the stopper rod caused by the large erosion amount of the existing stopper rod is solved; and has the characteristics of simple structure and low manufacturing cost.
Description
Technical Field
The utility model relates to a long-life continuous casting tundish stopper.
Background
The stopper rod of the continuous casting tundish is used in the continuous casting tundish, has the function of controlling the flow of molten steel in the tundish injected into the crystallizer, is a more key refractory material in the continuous casting production process, has long service life, and is beneficial to the stability of continuous casting production and the reduction of production cost; the stopper rod has short service life, is easy to cause production accidents and is not beneficial to reducing the production cost.
The original stopper rod is similar to a cylinder in shape, the upper end of the original stopper rod is slightly larger than the lower end of the original stopper rod, and the lower end of the original stopper rod is generally made into a smooth ellipsoid shape so as to be better matched with a tundish water feeding port to control the flow of molten steel. When the stopper rod is immersed in the molten steel and the steel slag in the tundish for a long time, the steel slag contains a large amount of oxides which are easy to react with the stopper rod material, so that the stopper rod immersed in the steel slag is corroded, the corrosion amount is increased along with the prolonging of the service life of the stopper rod, the service life of the stopper rod is shortened, and the stability of continuous casting production and the reduction of production cost are not facilitated. Therefore, in the continuous casting production process, prolonging the service life of the stopper becomes a problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
The utility model discloses its characterized in that is a long-life package stopper stick in middle of continuous casting to solve the problem among the above-mentioned background art.
The technical scheme that takes for realizing above-mentioned purpose is that a long-life continuous casting pouring basket stopper rod, includes the stopper rod body, the one end of stopper rod body is slick and sly ellipsoid structure, it is equipped with the circumference flange to lie in stopper rod slag line position on the outer circumference of stopper rod body, the overlook shape of circumference flange is circular, and the side view shape of circumference flange is circular, oval or square.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
1. The circumferential flange is arranged at the slag line part, so that the erosion amount which can be borne by the stopper rod is larger than that of the original stopper rod, and the problem of the service life reduction of the stopper rod in the prior art due to the large erosion amount is solved;
2. the tundish stopper has the advantages of simple structure, low manufacturing cost and the like, and can be slightly changed on the structure of the conventional stopper.
Drawings
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the structure of the present invention;
FIG. 3 is a view of the structure of the present invention, wherein the peripheral flange side is seen as an ellipse;
fig. 4 is a view of the circular structure of the present invention viewed from the side of the circumferential flange.
Detailed Description
The present invention will be further described with reference to the following embodiments and the accompanying drawings.
The utility model provides a long-life package stopper stick in middle of continuous casting, includes stopper stick body 1, the one end of stopper stick body 1 is slick and sly ellipsoid structure 2, as shown in fig. 1-4, it is equipped with circumference flange 3 to lie in stopper stick slag line position on the outer circumference of stopper stick body 1, the overlooking shape of circumference flange 3 is circular, and circumference flange 3 looks sideways at the shape and is circular, oval or square.
The utility model is characterized in that on the basis of the original stopper rod structure, the slag line part immersed in the steel slag part is thickened to form a circumferential flange 3, and the specific thickened part and the thickened size are determined according to the relevant parameters of the tundish; after the slag line part is thickened, the erosion amount which can be borne by the circumferential flange 3 part on the stopper rod body 1 is larger than that of the original stopper rod, and the problem that the service life of the conventional stopper rod structure is shortened due to the large erosion amount is solved.
