Abstract
The utility model discloses an inlaying type pouring nozzle used for connecting steel casting ladle. Step holes are arranged at the lower part of a main. Each hole wall is provided with thread grooves. A taper face is provided with tapered embedded bodies of the thread grooves or bar-shaped grooves, and the tapered embedded bodies are inlaid in the step holes. Material filling bodies are plug between the tapered embedded bodies and the step holes. The utility model has the advantages of low cost, uneasy disconnection of the embedded bodies and convenient fabrication, and can replace various metering pouring nozzle bricks and the pouring nozzle bricks with stoppers.
Description
Use apparatus for pouring on a kind of continuous casting steel machine tundish.
Continuous casting steel machine basket pouring system uses full homogeneous metering nozzle, inserted metering nozzle, direct compound metering nozzle always.The characteristics of full homogeneous metering nozzle are the chemical composition unanimities, good integrity, big, the anti-erosion of intensity, safe and reliable, but price is too high.The characteristics at the inserted mouth of a river are that the low-grade material of this body and function of the mouth of a river is made, and mosaics is made of high-grade material, and two parts are made respectively, become with the adhesive bond face then.Advantage is that price is low, and when shortcoming was imperfect bonding, mosaics floated easily or glides, and the danger that comes off is promptly arranged.Directly the characteristics of composite nozzle are the low-grade materials of this body and function, the high-grade material of complex, two part one-shot formings, once-firing.Advantage is that good integrity, price are low, and shortcoming is that manufacture difficulty is big, requires to solve the inconsistent problem of thermal coefficient of expansion of two kinds of raw materials.
Also have water nozzle brick on a kind of continuous casting steel machine tundish, require to be used with stopper.Though the charge is small for nozzle brick itself, supporting with it stopper costs an arm and a leg, and stopper combines by stopper brick and more piece sleeve brick, fractures easily in the use.
The purpose of this utility model provides a kind of inserted mouth of a river, accomplishes that price is low, the mosaics difficult drop-off, makes simply, can replace various metering nozzle bricks and be with the stopper nozzle brick.
The utility model purpose is achieved in that shoulder hole is arranged at body bottom, the mouth of a river, has thread groove on the hole wall.Mosaics is taper, and file has strip groove or thread groove on the conical surface.Mosaics embeds in the shoulder hole, fills in all around by bulk material to add the filler body that necessary additive is formed in addition.
Compared with the prior art, the utility model has following characteristics:
1, because mouth of a river body can adopt low-grade material to make, so price is low.What be worth proposition is that it does not need to use stopper, can greatly reduce production costs.
2, on the body of the mouth of a river step is arranged, mosaics can not floated.Mosaics is taper, can not glide from the filler body.Because concavo-convex each other groove structure between filler body and the body, between filler body and the mosaics, mutually interlocking together, so filler body and mosaics can not deviate from from body.In a word, the advantage that has the mosaics difficult drop-off.
3, make simply easily, do not require the bonding agent and the technique for sticking that are of high quality.
Fig. 1 is the inserted gate structure schematic diagram that proposes according to the utility model.
Fig. 2 is threaded groove mosaics front view.
Fig. 3 is a tape shape groove mosaics front view.
Below in conjunction with drawings and Examples concrete structure of the present utility model is described.
As shown in Figure 1, shoulder hole 4 is arranged at mouth of a river body 1 bottom, and thread groove is arranged on the hole wall, and taper mosaics 2 is embedded in the shoulder hole 4, and thread groove is as shown in Figure 2 also arranged on the conical surface of taper mosaics 2, is plugged with filler body 3 between taper mosaics 2 and shoulder hole 4.
Another embodiment and last example are basic identical, and the groove of just inlaying on the conical surface of shape mosaics 2 is illustrated in figure 3 as strip groove.
In actual production, also thread groove on the taper mosaics 2 or strip groove can be made screw boss or bar shaped boss, the effect that reaches will be the same.
Claims (2)
1, uses the inserted mouth of a river on a kind of continuous casting steel machine tundish, it is characterized in that shoulder hole (4) is arranged at mouth of a river body (1) bottom, thread groove is arranged on the hole wall, there is the taper mosaics (2) of thread groove or strip groove to be embedded in the shoulder hole (4) on the conical surface, between taper mosaics (2) and shoulder hole (4), is plugged with filler body (3).
2, the inserted mouth of a river according to claim 1 is characterized in that on the conical surface of taper mosaics (2) screw boss or strip boss being arranged.
