Description
Technical Field
The utility model belongs to the technical field of the continuous casting production, concretely relates to tundish for continuous casting production.
Background
In the continuous casting production process, drainage is usually carried out by using tundish drainage sand, namely the drainage sand is added into a tundish upper nozzle, when molten steel falls to a tundish after the ladle is cast, and the tundish molten steel reaches a certain liquid level, casting operation is carried out on the tundish, and hole burning operation is carried out on the drainage sand in the nozzle, so that the molten steel normally flows into a crystallizer through the nozzle for casting.
In the existing production, a water feeding port is added with tundish drainage sand before baking a tundish, and after the tundish is baked, the drainage sand in the water feeding port has a caking phenomenon, so that the pouring of the tundish water feeding port is difficult, and the phenomena of scattered flow, no opening during burning and the like are easy to occur; the method solves the problem of difficult drainage by adopting a mode of adding the drainage sand after baking the tundish, and is easy to cause safety accidents because a person stands on the hot tundish to add the drainage sand at the same time.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tundish for continuous casting production to the drainage sand caking that proposes in solving above-mentioned background art leads to the tundish mouth of a river to open and waters the difficult problem.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a tundish for continuous casting production is composed of a main body of tundish, which is a prismatic container with trapezoidal cross section and has three-layer structure, and the water inlets of tundish for discharging molten iron.
Furthermore, a channel is arranged inside the tundish nozzle and used for flowing out molten iron, a groove is formed inside the channel, a paper tube is clamped in the groove, and drainage sand is placed in the paper tube.
Furthermore, the bottom of the tundish nozzle is provided with a hole plugging cone which is in a circular truncated cone shape and used for plugging the drainage sand and the molten iron.
Furthermore, the outermost layer of the tundish body is a heat-insulating layer and is poured by an asbestos plate, heat-insulating bricks or light castable.
Furthermore, the middle layer of the tundish body is a permanent layer and is made of clay bricks.
Furthermore, the innermost layer of the tundish body is a working layer, and the working layer is made of a heat insulation plate spraying paint.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a set up the recess in the middle package mouth of a river, can place fiber container and drainage sand in the recess after the middle package toasts, avoided drainage sand together toasting and the drainage sand caking that causes with the middle package, the middle package mouth of a river is opened and is watered the problem of difficulty.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic cross-sectional view of the present invention;
fig. 3 is a schematic structural view of the tundish nozzle of the present invention;
in the figure: 1. a tundish body; 2. a tundish nozzle; 201. a groove; 202. a paper tube; 203. draining sand; 204. and (5) plugging the cone.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a following technical implementation scheme:
referring to fig. 1 to 3, a tundish for continuous casting production includes a tundish body 1 and tundish nozzles 2, the tundish body 1 is a prismatic container with a trapezoidal section and has a three-layer structure, a plurality of tundish nozzles 2 are distributed on the bottom of the container for discharging molten iron, and the tundish nozzles 2 are distributed on the same straight line and fixedly connected with the tundish body 1.
Furthermore, a channel is arranged inside the tundish nozzle 2 and used for flowing out molten iron, a groove 201 is formed inside the channel, a paper tube 202 is clamped in the groove 201, and drainage sand 203 is placed in the paper tube 202.
Further, the bottom of the tundish nozzle 2 is provided with an eye blocking cone 204, and the eye blocking cone 204 is in a circular truncated cone shape and is used for blocking the drain sand 203 and the molten iron.
Further, the outermost layer of the tundish body 1 is a heat-insulating layer and is poured by an asbestos board, heat-insulating bricks or light castable.
Further, the middle layer of the tundish body 1 is a permanent layer and is made of clay bricks.
Further, the innermost layer of the tundish body 1 is a working layer, and the working layer is made of heat insulation plate spraying paint.
The utility model discloses a theory of operation and use flow:
when the utility model is used, the tundish is baked at first, the tundish is moved to the position above the crystallizer after baking is finished, then the drainage sand is wrapped and rolled by the paper tube, the tundish is filled from the lower part of the water gap, the steel ladle is poured again after plugging is carried out by the plugging cone, and the molten steel is injected into the tundish; when the nozzle is opened for casting, the hole blocking cone is removed for hole burning operation, the casting sand in the nozzle is easier to be boiled and even reaches the self-opening effect, the molten steel in the tundish is easier to flow into the crystallizer through the device, the flow scattering phenomenon can not occur, and the normal casting of the tundish is ensured.
The utility model discloses a set up the recess in the middle package mouth of a river, can place fiber container and drainage sand in the recess after the middle package toasts, avoided drainage sand together toasting and the drainage sand caking that causes with the middle package, the middle package mouth of a river is opened and is watered the problem of difficulty.
