Description
Technical Field
[0001] The present application relates to the technical field of tundish temperature measuring devices, and in particular to a base device capable of fixing temperature measuring tubes of various models. Background Art
[0002] The continuous casting tundish is a molten steel transition device between the ladle and the crystallizer, and has important applications in the steelmaking field. In the actual production process, the continuous casting tundish uses a continuous temperature measuring device to monitor the temperature change trend of the internal molten steel in real time, so as to control the progress of the production process.
[0003] In the related art, the continuous temperature measuring device is mainly composed of a continuous temperature measuring tube, a base body, a connecting tube and other supporting photoelectric conversion devices; when in use, the base body is placed on the sand filling hole of the tundish cover, the continuous temperature measuring tube passes through the through hole in the middle of the base body and is inserted into the tundish, and then the connecting tube and other accessories are assembled, and the temperature inside the tundish can be continuously measured.
[0004] With respect to the above-mentioned related technologies, there are the following problems: the existing continuous temperature measuring devices have poor applicability, and the base bodies and continuous temperature measuring tubes produced by different manufacturers have different sizes and cannot be used together. In addition, since the continuous temperature measuring tube is hollow inside, a part of it is inserted into the molten steel during normal casting, and the buoyancy often causes the continuous temperature measuring tube itself or the base body to tilt to one side. Affected by the above-mentioned factors, the existing continuous temperature measuring devices have poor use effect and poor temperature measurement accuracy, so there is room for improvement.

[0034] Reference Figure 1 and Figure 3The combined gasket 3 includes a plurality of arc-shaped combined parts 31 spliced with each other. In the present embodiment, three combined parts 31 are provided. The combined parts 31 include a first ring 311, a second ring 312 and a third ring 313 from the outside to the inside. The first ring 311, the second ring 312 and the third ring 313 are integrally formed. A clamping groove 314 for the clamping ring 23 to abut is formed between the first ring 311 and the third ring 313. The bottom wall of the second ring 312 becomes the top wall of the clamping groove 314. The third ring 313 passes through the through hole 21. The outer wall of the third ring 313 abuts against the inner wall of the through hole 21. The continuous temperature measuring tube 5 passes through the third ring 313. A supporting protrusion 51 is integrally formed on the peripheral wall of the continuous temperature measuring tube 5. The bottom wall of the supporting protrusion 51 is in the shape of an arc and can abut against the top of the third ring 313, thereby limiting the continuous temperature measuring tube 5.
[0035] Reference Figure 1 and Figure 4 A plurality of limit blocks 24 are integrally formed on the inner wall of the base body 2, and the limit blocks 24 are distributed along the circumferential direction of the inner wall of the base body 2. The limit blocks 24 are located above the supporting protrusions 51, and a rotating cover plate 6 is arranged between the limit blocks 24 and the supporting protrusions 51. A plurality of notches 61 for the limit blocks 24 to pass through are provided on the peripheral wall of the rotating cover plate 6 to facilitate installation of the rotating cover plate 6. A connecting port 62 for the top end of the continuous temperature measuring tube 5 to pass through is provided on the rotating cover plate 6 along the thickness direction. The inner diameter of the connecting port 62 is smaller than the diameter of the supporting protrusions 51. The top wall of the supporting protrusions 51 is a plane and can be abutted against the bottom wall of the rotating cover plate 6, so that the supporting protrusions 51 can abut between the combined gasket 3 and the rotating cover plate 6, thereby maintaining the stability of the continuous temperature measuring tube 5 and thereby improving the measurement accuracy.

The combined gaskets 3 of different thicknesses can adapt to the installation of continuous temperature measuring tubes 5 of different sizes; the continuous temperature measuring tube 5 is inserted into the continuous casting tundish 1 through the combined gasket 3, and the notch 61 of the rotating cover plate 6 is aligned with the limit block 24, so that the rotating cover plate 6 comes under the limit block 24, and the rotating cover plate 6 is rotated so that the bottom wall of the limit block 24 abuts against the surface of the rotating cover plate 6. At this time, the continuous temperature measuring tube 5 abuts between the rotating cover plate 6 and the combined gasket 3 through the supporting protrusion 51, thereby preventing the continuous temperature measuring tube 5 from tilting and affecting the measurement accuracy.
