Description

Technical Field

[0001] The utility model relates to the field of crystallizer copper tubes, in particular to a non-contact continuous taper detection device for crystallizer copper tubes. Background Art

[0002] Heat transfer in the mold is the key to controlling the output and quality of continuous casting billets. In the copper tube of the mold, the molten steel forms a billet shell of a certain shape due to cooling. As the billet moves downward, the temperature continues to drop and shrink, forming a gap between the mold and the billet shell, which is called an air gap.

[0003] The existence of air gap reduces the cooling effect. At the same time, if the shell is separated from the inner wall of the crystallizer too early, the shell will be deformed under the static pressure of molten steel. Therefore, the inner cavity of the crystallizer copper tube should be tapered, and the upper part should be larger and the lower part should be smaller to reduce the air gap.

[0004] The size of the taper must be appropriate. The principle is that the inner shape of the copper tube of the crystallizer is consistent with the shrinkage law of the solidified billet shell to reduce the air gap thermal resistance. If the taper curve of the copper tube does not match the design curve or changes significantly due to the abrasion of high-temperature molten steel during long-term use, it will not only affect the output and quality of the billet, but may even cause serious production accidents such as steel leakage. Therefore, the detection of taper becomes an indispensable part of the billet production process.

[0005] During the process of detecting the internal dimensions of the crystallizer copper tube, it is necessary to provide a stable clamping function for the crystallizer copper tube to improve the detection accuracy of the internal taper of the crystallizer copper tube. Therefore, a non-contact continuous taper detection device for the crystallizer copper tube is proposed. Utility Model Content

[0027] In this example, see Figure 1 and Figure 4 The utility model provides a technical solution: comprising a support plate 1, a support leg 11 is fixed to the bottom of the support plate 1, and is used to provide support for the bottom of the support plate 1; a taper detection controller 2 is provided at one end of the top of the support plate 1, and a push rod 21 is installed on the inner side of the taper detection controller 2, and a laser displacement sensor 22 is provided at one end of the push rod 21;

[0028] Among them, the taper detection controller 2 is an existing taper detection controller, and the push rod 21 is a push rod used to drive the laser displacement sensor 22 to extend and retract. At the same time, the push rod 21 is slidably connected inside the taper detection controller 2, and the laser displacement sensor 22 is used to detect the inner diameter value of the crystallizer copper tube at the current position, thereby obtaining the displacement change value of the inner wall of the crystallizer copper tube; during the measurement process, the laser displacement sensor 22 follows the push rod 21 to move forward in the inner cavity of the crystallizer copper tube to detect the diameter value change of the inner cavity of the copper tube at each position value. The laser displacement sensor 22 and the taper detection controller 2 are respectively connected by signal lines, so that the data detected by the laser displacement sensor 22 can be displayed in real time on the screen at the front end of the taper detection controller 2. The taper detection controller 2, the push rod 21 and the laser displacement sensor 22 are all existing mature technical equipment, and will not be elaborated on here.

[0029] For further information, see Figure 1 、 Figure 2 and Figure 3 A support frame 3 is fixed to the top of the support plate 1 at one end away from the taper detection controller 2, and a connecting shaft 6 is installed at the output end of the drive motor 7 at one end inside the support frame 3.
