Description
Technical Field
The utility model relates to a water feeding port and upper slide plate combined structure, which belongs to the technical field of steel-making refractory materials in metallurgical industry.
Background
The ladle sliding gate consists of an upper gate, an upper sliding plate, a lower sliding plate and a lower gate, and is a channel for molten steel to enter a tundish from a ladle, thereby playing the roles of sealing the molten steel flow and regulating the flow.
The upper nozzle is connected with the upper sliding plate through a fire clay or a cement gum pad, and the function of sealing molten steel is achieved. Because the contact surfaces between the upper nozzle and the upper sliding plate are both in a plane structure, the contact area is smaller, and the sliding plate brick is easy to cause the loose connection between the upper sliding plate and the matched upper nozzle or dislocation due to scouring in the use process, so that the steel running accident is often caused; and the slide plate brick can not be used for many times, thereby causing great influence on the production of a steel mill, not only increasing the labor intensity of workers, but also increasing a large amount of labor cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a go up mouth of a river and top slide integrated configuration can make the top slide connect inseparabler, firm with the top slide, prevents to run the steel phenomenon because of the two is connected inseparable appearing in the production process, has effectively improved the life of slide brick, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
a combined structure of a water feeding port and an upper sliding plate comprises the water feeding port, the upper sliding plate, a wavy surface or a sawtooth surface, a groove, a boss and a central hole, wherein the bottom surface of the water feeding port is provided with the groove, the boss matched with the groove is arranged on the upper surface of the upper sliding plate, the groove on the bottom surface of the water feeding port is clamped on the boss on the upper surface of the upper sliding plate, and the water feeding port and the upper sliding plate are both provided with the central holes which are communicated with each other; the outer surfaces of the grooves and the bosses are both wave surfaces or sawtooth surfaces which are matched with each other, and fire clay is smeared on the wave surfaces or the sawtooth surfaces of the grooves and the bosses.
The wave surface or the sawtooth surface matched with the outer surface of the groove and the outer surface of the boss are meshed together.
The groove on the bottom surface of the upper water gap and the boss on the upper sliding plate are in matched conical shapes.
The utility model has the advantages that: the contact surface of the upper nozzle and the upper sliding plate is a wavy surface or a sawtooth surface, so that the contact area is increased, the resistance of molten steel penetrating through the contact surface is increased, and meanwhile, the positioning function is realized, and the connection dislocation of the upper nozzle and the upper sliding plate is reduced. The upper sliding plate and the upper water gap are connected more tightly and firmly, and the steel running phenomenon caused by the untight connection of the upper sliding plate and the upper water gap in the production process is prevented; and the wave surface can bear stress better, and the service life of the sliding plate brick is effectively prolonged.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: the device comprises a water feeding port 1, an upper sliding plate 2, a wavy surface or a sawtooth surface 3, a groove 4, a boss 5, a central hole 6 and fire clay 7.
Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached figure 1, the combined structure of the water feeding port and the upper sliding plate comprises a water feeding port 1, an upper sliding plate 2, a wavy surface or sawtooth surface 3, a groove 4, a boss 5 and a central hole 6, wherein the groove 4 is formed in the bottom surface of the water feeding port 1, the boss 5 matched with the groove 4 is arranged on the upper surface of the upper sliding plate 2, the groove 4 in the bottom surface of the water feeding port 1 is clamped on the boss 5 on the upper surface of the upper sliding plate 2, through holes are formed in the central parts of the water feeding port 1 and the upper sliding plate 2, and the through holes of the water feeding port 1 and the upper sliding plate 2 are communicated with each other to form the central hole 6; the outer surfaces of the grooves 4 and the bosses 5 are both wave surfaces or sawtooth surfaces 3 which are matched with each other, and fire clay 7 is smeared on the wave surfaces or the sawtooth surfaces 3 of the grooves 4 and the bosses 5.
In this example, with reference to fig. 1, the overall cross-section of the groove 4 in the bottom surface of the nozzle 1 and the overall cross-section of the projection 5 on the upper slide 2 are of matching conical shape. The groove 4 and the boss 5 are clamped together up and down. The bottom surface of the groove 4 and the end surface of the boss 5 are both wave surfaces which can be meshed together, and the wave surfaces are coated with fire clay 7. The bottom surface of the groove 4 is meshed with the wavy surface of the end surface of the boss 5, so that the contact area is increased, the resistance of molten steel penetrating through the contact surface is increased, and meanwhile, the positioning function is realized, and the connection dislocation of the upper water gap and the upper sliding plate is reduced. Thereby leading the connection between the upper sliding plate 2 and the upper water gap 1 to be more compact and firm, and preventing the steel leakage phenomenon caused by the untight connection between the upper sliding plate and the upper water gap in the production process; and the wave surface can bear stress better, and the service life of the sliding plate brick is effectively prolonged.
