Description

Technical Field

[0001] The utility model relates to the technical field of amorphous strip production, in particular to a stopper rod control device for amorphous strip production. Background Art

[0002] The tundish, also known as the "ladle", is quite common in the production process of amorphous strips. The bottom of the tundish has a molten steel outlet, and generally, the opening and closing of the molten steel outlet are achieved by the lifting of the stopper rod. The prior art, such as the Chinese utility model patent with the application number 201920492610.6, a rapid pressing device for the stopper rod of amorphous strips, drives the stopper rod to lift through a hydraulic cylinder, and presses the upper end of the stopper rod through a pressing structure, so that the lower end of the stopper rod can tightly abut against the molten steel outlet to prevent liquid overflow.

[0003] However, the tundish is very large in volume and the stopper rod is very long. During the production process, the molten steel in the tundish often impacts the stopper rod. In this way, even if there is a slight deviation in the angle of the stopper rod, a gap will be generated between the stopper rod and the molten steel outlet, resulting in frequent leakage of molten steel at the molten steel outlet. In addition, due to the large weight of the tundish, the foundation may sink over time, which may also cause the angle of the stopper rod to deviate. Therefore, the present application proposes a stopper rod control device for amorphous strip production, which can correct the deviation of the stopper rod in time and effectively prevent the leakage of molten steel at the molten steel outlet.

Detailed Description of the Preferred Embodiments

[0018] The following further elaborates on the specific embodiments of the present utility model in Figures 1-3 combination with the attached drawings.

[0019] From Figures 1-3Provided is a stopper rod control device for amorphous strip production according to the present utility model, which includes a tundish 10, a stopper rod 20 and a stopper rod lifting mechanism 30. The stopper rod lifting mechanism 30 is used to control the lifting of the stopper rod 20 to open and close the molten steel outlet at the bottom of the tundish 10. The above is the prior art and will not be elaborated here. The main improvement of the present utility model lies in that: a vertical adjustment mechanism 40 is connected between the stopper rod lifting mechanism 30 and the stopper rod 20. The function of the vertical adjustment mechanism 40 is to adjust the stopper rod 20 vertically to prevent leakage of the molten steel outlet due to the offset of the stopper rod 20.

[0020] The following is a specific embodiment of the vertical adjustment mechanism 40:

[0021] It includes a fixing plate 41, a horizontal detection plate 42 and an adjustment cylinder 43. The fixing plate 41 and the horizontal detection plate 42 are respectively fixedly connected to the stopper rod lifting mechanism 30 and the upper end of the stopper rod 20. The number of adjustment cylinders 43 is at least 3, and both ends of the adjustment cylinder 43 are respectively rotatably connected to the fixing plate 41 and the horizontal detection plate 42. When the stopper rod 20 has an angular offset, multiple adjustment cylinders 43 can drive the horizontal detection plate 42 to move through expansion and contraction, and the verticality of the stopper rod 20 is adjusted through the movement of the horizontal detection plate 42, so as to ensure good contact between the bottom of the stopper rod 20 and the molten steel outlet.

[0022] The upper end of the stopper rod 20 is detachably fixed to the lower surface of the horizontal detection plate 42, which is convenient for disassembling the stopper rod 20.

[0023] In some embodiments, an internal thread pipe 421 is integrally formed on the lower surface of the horizontal detection plate 42, and a thread corresponding to the internal thread pipe 421 is provided on the outer side of the upper end of the stopper rod 20. The stopper rod 20 and the horizontal detection plate 42 are connected by threads, which is convenient for connection and disassembly. In other embodiments, the stopper rod 20 and the horizontal detection plate 42 can also be connected by bolts.

[0024] A horizontal detection device 50 is provided on the horizontal detection plate 42 to detect the levelness of the horizontal detection plate 42. The stopper rod 20 is perpendicular to the horizontal detection plate 42, so as to detect the verticality of the stopper rod 20. When it is detected that the horizontal detection plate 42 is level, it means that the stopper rod 20 is vertical.

[0025] In this embodiment, the horizontal detection device 50 includes a fixed shaft 51 and a balance rod 52. The lower end of the fixed shaft 51 is fixedly connected to the surface of the horizontal detection plate 42. The balance rod 52 is rotatably connected to the upper end of the fixed shaft 51. When the plug rod 20 is deflected, one end of the balance rod 52 will inevitably point to the lower end of the horizontal detection plate 42 under the action of gravity. By observing the position of the balance rod 52, it is convenient to observe the specific position to which the plug rod 20 is deflected, so as to facilitate the operator to operate the corresponding adjusting cylinder 43 to extend and raise the lower position of the horizontal detection plate 42.

[0026] In order to make the balance rod 52 more sensitive, a cavity is provided inside the balance rod 52 along the length direction, and a detection ball 53 is rotatably provided in the cavity. At the beginning, the detection ball 53 can be set in the middle position. When the plug rod 20 has an angular deflection, one side of the horizontal detection plate 42 is at a lower position, so that the detection ball 53 automatically rolls towards the lower direction, which drives the balance rod 52 to quickly point to the lower position of the horizontal detection plate 42. In addition, when the detection ball 53 rolls to one end of the balance rod 52, it means that the horizontal detection plate 42 is no longer horizontal.

[0027] In order to facilitate observing the specific magnitude of the angular deflection of the plug rod 20, a protractor 54 is fixed on the balance rod 52, and a pointer 55 is rotatably provided on the balance rod 52. A counterweight 56 is fixed below the rotating shaft of the pointer 55. The gravitational force of the counterweight 56 will keep the pointer 55 vertical. The 0-point position of the protractor 54 is in the middle position. In this way, when the horizontal detection plate 42 is tilted, the protractor 54 will also tilt to one side, and the pointer 55 will deviate from the 0 point of the protractor 54. The greater the deviation, the greater the tilt of the horizontal detection plate 42. According to the deviation degree, it is also convenient for the operator to operate the adjusting cylinder 43 to perform corresponding expansion and contraction.

[0028] A plug rod control device for amorphous strip production has the following working principle:

[0029] When the plug rod 20 has an angular deflection, the balance rod 52 will automatically point to the lowest position of the horizontal detection plate 42 under the action of gravity. The operator can operate the corresponding adjusting cylinder 43 to expand and contract according to the direction pointed by the balance rod 52 and the magnitude of the deviation of the pointer 55 from the 0 point on the protractor 54. By adjusting the expansion and contraction of the adjusting cylinder 43, the levelness of the horizontal detection plate 42 is adjusted, which is convenient for controlling the verticality of the plug rod 20, so that the lower end of the plug rod 20 maintains good contact with the molten steel outlet at the bottom of the tundish 10 and prevents liquid leakage.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
