Abstract
The special-shaped tundish die comprises an inner die, a tundish permanent layer and an impact area protection plate, wherein the inner die is arranged in an area defined by the tundish permanent layer and the impact area protection plate, one end of the tundish permanent layer is connected with the side part of the impact area protection plate, and one end of the impact area protection plate, which is positioned at the inner side of the tundish permanent layer, is defined by the inner die and the tundish permanent layer to form a triangular filling area for filling dry materials. The utility model adopts the dry material to fill the triangular filling area as the supporting part, can ensure that the extending part of the guard plate is completely eroded in the production process, and the condition that the permanent layer of the tundish is eroded can not occur, and has the characteristics of simple structure, low processing and manufacturing cost and long service life of the guard plate.
Description
Technical Field
The utility model belongs to the technical field of continuous casting tundish structure design, and particularly relates to a special-shaped tundish mould.
Background
At present, a tundish adopted by a billet continuous casting machine 8 is a special-shaped tundish for producing ladle types, and the tundish has the functions of preventing secondary oxidation of molten steel, promoting floating of impurities, preserving heat of the molten steel, shunting, improving continuous casting operation rate and the like. Because the counter-ladle type is adopted, the steel receiving port of the tundish is arranged on the edge, the whole steel receiving port has small area, and the ferrostatic pressure born by the steel receiving port is larger than that of other types of tundishes when molten steel flows into the tundish from the ladle, so a tundish current stabilizer and a protective plate are arranged in the area to ensure the stable flow field of the tundish and the lifting of a continuous casting furnace;
when the backplate was installed in the middle package knot, it is exposed outside (220 mm) to have one section to stretch out the position, does not have supporting strength, and the shortcoming of this kind of backplate lies in: in the production process, molten steel is continuously poured on the protective plate in the impact area, and due to the influence of strong molten steel static pressure of a steel port, the extended part frequently collapses and is seriously corroded, so that a tundish is taken off the production line in advance, the continuous casting operation rate is reduced, the safety in the production process is greatly influenced, and the labor intensity of workers is greatly increased. But if the extended part of the protective plate is not used, the protective plate type is directly changed, which can cause great influence on the flow field of the whole tundish, the inclusion in the tundish is not easy to float upwards, the static pressure of molten steel distributed to each flow is different, which can also cause great influence on the center pouring operation,
therefore, in the using process of the tundish protective plate, the situation that the support strength of the extending part is improved and the tundish protective plate does not collapse is a problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a special-shaped tundish die, which is used for solving the problems in the background technology and has the characteristics of simple structure, low processing and manufacturing cost and long service life of a guard plate.
The technical scheme adopted for achieving the purpose is that the special-shaped tundish die comprises an inner die, a tundish permanent layer and an impact area protection plate, wherein the inner die is arranged in an area defined by the tundish permanent layer and the impact area protection plate, one end of the tundish permanent layer is connected with the side part of the impact area protection plate, and one end, located on the inner side of the tundish permanent layer, of the impact area protection plate, and the inner die and the tundish permanent layer are combined to define a triangular filling area for filling dry materials.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
1. The triangular filling area is filled with the dry material to serve as a supporting part, the dry material is used for filling, the supporting strength of the extending part of the guard plate of the impact area is increased, and the collapse phenomenon is not easy to occur;
2. in the production process, if the extending part of the guard plate in the impact area is completely corroded, the situation that the permanent layer of the tundish is corroded can not occur due to the fact that the supporting part is filled with dry materials;
3. the installation of the supporting plate is cancelled, so that the labor intensity is reduced;
4. simple structure, low processing and manufacturing cost and long service life of the guard plate.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic view of the present invention.
Detailed Description
The utility model is further described with reference to the following examples and the accompanying drawings.
As shown in fig. 1, a special-shaped tundish die comprises an inner die 1, a tundish permanent layer 2 and an impact area protection plate 3, wherein the inner die 1 is arranged in an area surrounded by the tundish permanent layer 2 and the impact area protection plate 3, one end of the tundish permanent layer 2 is connected with the side part of the impact area protection plate 3, and one end of the impact area protection plate 3, which is positioned at the inner side of the tundish permanent layer 2, is surrounded by the inner die 1 and the tundish permanent layer 2 to form a triangular filling area 4 for filling dry materials.
The utility model adopts the mode of the prior tundish protection plate to be unchanged, ensures the molten steel flow field in the tundish, only changes the inner mould 1 used for knotting the tundish, cuts off the position area of the inner mould 1 on the impact area protection plate 3, changes the original outer triangle into the inner triangle, cancels the position to install the retaining wall and completely fills the tundish with dry materials.
In the specific implementation of the utility model, the inner die 1 is positioned in the position area of the impact area protection plate 3 (the length of the extending part of the impact area protection plate 3 is measured to be 220 mm), after the on-site tundish measurement is carried out, the inner die 1 is determined to be positioned at 160mm of the extending part of the impact area protection plate 3, and the cutting is carried out at the position 250mm close to the tundish permanent layer, so as to form the triangular filling area 4.
At the 3 positions that stretch out of impact zone backplate, cancel original erection bracing board position, take all schemes of using dry-type material to fill and carry out the knot to increase the support nature at the backplate position of stretching out, can make the backplate stretch out the position and corrode in the production process and accomplish, the condition that can not appear corroding to middle package permanent layer takes place.
