Abstract
The utility model relates to an anti-loosening stopper rod, belonging to the technical filed of metallurgy refractory material. The anti-loosening stopper rod is characterized in that the bottom screw hole of the stopper rod is square, and the square has a certain depth, a screw rod which is connected with a stopper rod mechanism and the stopper rod is screwed into a nut in a stopper rod body, the gap of the corner part between the screw rod and the bottom square screw hole of the stopper rod is filled with fire clay, the fire clay is baked by the tundish, the fire clay is fully contacted with the screw rod after being baked, so that the stopper rod is prevented from loosening when being used. The anti-loosening stopper rod can prevent the stopper rod from loosening on the basis that the service life of the stopper rod is ensured, and prevents the flow control precision of the stopper rod from fluctuating to affect the quality of casting blanks.
Description
One: technical field
The utility model relates to a kind of stopper that is used for metallurgical anti-material.
Two: background technology
The stopper that present each steel mill generally uses is to be connected with mechanism by screw rod, and silk hole, a stopper bottom major part is circular, but has following problem:
Screw rod is connected with nut in the stopper silk hole, underway is wrapped in baking and the tundish use, because the thermal expansion properties of nut and the thermal expansion properties of screw rod are inconsistent, flow through the influence of shaking in the journey in control adding stopper mechanism, the loosening situation of screw rod and nut often appears, influenced the control accuracy of stopper, slab quality has been produced considerable influence.
Three: summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of long service life, is difficult for producing loosening locking stopper.
For achieving the above object, the technical scheme that the utility model adopted is as follows:
A kind of locking stopper comprises the stopper body, the silk hole that is provided with screw rod in the stopper body and cooperates with screw rod, and the silk hole, bottom of described stopper is filled with refractory material greater than screw diameter between silk hole and the screw rod.
Above-mentioned locking stopper, the silk hole, bottom of described stopper is a square opening.
Above-mentioned locking stopper, described square opening are that the length of side is the square opening of 55mm; The height of square opening is 20mm.
The utility model is designed to hole greater than screw diameter with the diameter in stopper bottom silk hole, and the shape in hole can design as required, such as being designed to the edgewise wire hole.
After nut in screw rod and the stopper is connected, a certain amount of refractory material is filled in gap, bight in screw rod and edgewise wire hole, refractory material is selected fire clay for use, during the tundish baking, fire clay is sintered, and fully contacts with screw rod, eliminated because screw rod and nut heat expansion are inconsistent, flow through the stopper that shake causes in the journey in stopper mechanism control and become flexible phenomenon, and the loosening problem that occurs in the use, also guarantee the service life of stopper simultaneously.
Four: description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the A-A schematic diagram of Fig. 1;
Fig. 3 is implementation result figure of the present utility model.
Wherein 1, the edgewise wire hole, 2, nut, 3, the stopper body, 4, fire clay, 5, screw rod.
Five: the specific embodiment:
Specific embodiment with integrated structure schematic diagram and implementation result figure is described in detail the utility model below:
As Fig. 1,2 structural representation, a kind of locking stopper, comprise stopper body 3 and screw rod 5, screw rod 5 is connected with the nut 2 of stopper body 3 inside, the silk hole, bottom of stopper body 3 is edgewise wire hole 1, after screw rod 5 was screwed into edgewise wire hole 1, filled by fire clay 4 in the gap, bight of formation, as shown in Figure 3.
When screw rod 5 is installed, guarantee that screw rod 5 is connected closely with the nut 2 of stopper body 3 inside, fill with fire clay 4 in the gap, bight that forms with edgewise wire hole 1 after screw rod 5 installs, and guarantees fire clay 4 fillings evenly, fully contacts with screw rod 5 to guarantee baking back fire clay 4.
In the use, fire clay 4 is sintered, and fully contacts with screw rod 5, plays the purpose that prevents that stopper is loosening.
Claims (4)
1. a locking stopper comprises the stopper body, and the silk hole that is provided with screw rod in the stopper body and cooperates with screw rod is characterized in that: the silk hole, bottom of described stopper is filled with refractory material greater than screw diameter between silk hole and the screw rod.
2. locking stopper according to claim 1 is characterized in that, the silk hole, bottom of described stopper is a square opening.
