Detailed Description of the Embodiment

[0021] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is made with reference to the accompanying drawings. Although some embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be construed as limited to the embodiments described herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present utility model. It should be understood that the drawings and embodiments of the present utility model are only for exemplary purposes and are not used to limit the protection scope of the present utility model.

The positive direction of the Z-axis represents the upper side, and the negative direction of the Z-axis represents the lower side. The X-axis in the accompanying drawings represents the horizontal direction and is specified as the front-and-back position. The positive direction of the X-axis represents the front side, and the negative direction of the X-axis represents the rear side. The Y-axis in the accompanying drawings represents the left-and-right position. The positive direction of the Y-axis represents the left side, and the negative direction of the Y-axis represents the right side. It should be noted that the meanings represented by the foregoing Z-axis, Y-axis, and X-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0023] As used herein, the term "comprising" and its variations are open-ended, that is, "including but not limited to"; the term "based on" is "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". The relevant definitions of other terms will be given in the following description. It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish different devices, modules, or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules, or units.

[0024] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0025] In the related art, the support surface for placing the tundish in the tundish car may be inclined relative to the horizontal plane. When the support surface is inclined, if the tundish is placed on this support surface, the whole tundish will also be inclined relative to the horizontal plane. At this time, it will affect the refining of molten steel in the tundish. For example, when the inclined tundish is baked by a plurality of horizontally arranged burners, it is not easy to ensure the consistency of the distances from the burners, which easily leads to uneven temperature distribution inside the tundish after baking, and will affect the uniform heating of the molten steel in the tundish. Another example is that the inclined tundish will cause the molten steel not to fill the entire inner cavity of the tundish, resulting in a smaller amount of molten steel that can be accommodated. Thus, at the same pouring rate, the residence time of the molten steel in the tundish will be correspondingly reduced, which will affect the floating of inclusions in the molten steel. Therefore, it greatly affects the quality of the molten steel refined in the tundish.

[0026] In view of the problems existing in the above-mentioned related art, the present invention provides a tundish to eliminate the influence of the uneven support surface on the refining of molten steel in the tundish. The following will be described in detail with specific embodiments.

[0027] As Figure 1As shown in the figure, a tundish provided by an embodiment of the present utility model includes a tundish body 1, a first spirit level 2, a second spirit level 3, and a height adjusting device 4; the first spirit level 2 is arranged on the tundish body 1 and extends along the length direction of the tundish body 1 for detecting the inclination degree of the length direction relative to the horizontal plane; the second spirit level 3 is arranged on the tundish body 1 and extends along the width direction of the tundish body 1 for detecting the inclination degree of the width direction relative to the horizontal plane; the four height adjusting devices 4 are respectively arranged at the four corners of the tundish body 1, the upper end of the height adjusting device 4 is connected to the tundish body 1, and the lower end is used for supporting on the support surface.

It can be understood that the first spirit level 2 is arranged on the tundish body 1 and extends along the length direction of the tundish body 1. In this way, when the length direction of the tundish body 1 is inclined relative to the horizontal plane, the first spirit level 2 will display the corresponding reading to detect the inclination degree of the length direction relative to the horizontal plane; the second spirit level 3 is arranged on the tundish body 1 and extends along the width direction of the tundish body 1. In this way, when the width direction of the tundish body 1 is inclined relative to the horizontal plane, the second spirit level 3 will display the corresponding reading to detect the inclination degree of the width direction relative to the horizontal plane.

[0029] In this embodiment, the first spirit level 2 is arranged on the tundish body 1 and extends along the length direction of the tundish body 1, which can detect the inclination degree of the length direction relative to the horizontal plane.

In this way, when the tundish body 1 is inclined in the length direction or the width direction, the corresponding height adjusting device 4 can be adjusted accordingly until the tundish body 1 is horizontal. Therefore, when the support surface is inclined relative to the horizontal plane, the tundish body 1 placed on the support surface will tilt accordingly. At this time, the inclination degree of the tundish body 1 can be detected by the first spirit level 2 and the second spirit level 3, and the corresponding height adjusting device 4 can be adjusted according to the inclination degree to change the inclination degree of the tundish body 1 relative to the horizontal plane until the tundish body 1 is in a horizontal state, thereby eliminating the influence of the uneven support surface and improving the quality of the steel refined by the tundish.

With such a setting, the detachable installation of the first level gauge 2 and the second level gauge 3 is realized by means of magnetic attraction. Using the magnetic attraction method can reduce the dependence on tools, and the operator can disassemble and assemble the level gauge without carrying additional tools, and the disassembly and assembly are more efficient and fast.

[0042] Optionally, as Figure 1 shown, a first heat insulation plate is covered on the groove wall surface of the first groove 1111; a second heat insulation plate is covered on the groove wall surface of the second groove 1121.
