Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective slag measurement, in particular to a device for measuring the total thickness of protective slag of a continuous casting crystallizer. Background Art
[0002] The crystallizer is the core equipment of the continuous casting machine. Its main function is that when the molten steel is in the crystallizer, the copper wall of the crystallizer is cooled by soft water, and then the molten steel in the crystallizer is cooled by the copper wall, so that the molten steel gradually cools down and crystallizes to form a cast billet. The crystallizer protective slag is a very important key material in the continuous casting production process. The protective slag structure is composed of a powder slag layer, a sintered layer and a liquid slag layer from top to bottom. It mainly has the functions of heat insulation, lubrication, preventing secondary oxidation of molten steel, and absorbing inclusions.
[0003] The thickness of the protective slag layer is an important criterion for measuring whether the performance and dosage of the protective slag match the steel grade and related continuous casting process parameters. If the slag layer is too thin, it is easy to cause adhesion between the solidified billet shell and the crystallizer wall, and even steel leakage in severe cases; if the slag layer is too thick, the channel between the meniscus liquid slag flowing into the billet shell and the copper wall will be blocked, so that the liquid slag cannot flow smoothly and achieve lubrication and other effects. Therefore, controlling the appropriate thickness of the slag layer in the continuous casting production process is an important means to ensure the quality of the casting, so it is necessary to frequently measure the thickness of the protective slag layer in the crystallizer.
[0004] However, the existing measuring device cannot be fixedly connected to the crystallizer when in use, and the crystallizer may vibrate during operation, causing the measuring device to shake, resulting in instability in the measurement of the protective slag thickness and affecting the measurement results.

[0025] According to an embodiment of the utility model, a device for measuring the total thickness of continuous casting mold protection slag is provided.
[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 5 As shown, a device for measuring the total thickness of continuous casting crystallizer protective slag according to an embodiment of the utility model includes a crystallizer connecting frame 1, two groups of clamping components 2 are arranged at the bottom end of the crystallizer connecting frame 1, a timer 3 is arranged on one side of the crystallizer connecting frame 1, a scale 5 is arranged at the top of the crystallizer connecting frame 1 through a control and adjustment component 4, an asbestos circular plate 6 is arranged at the bottom end of the scale 5, and a measuring wire 7 is arranged through the middle of the scale 5 and the asbestos circular plate 6.
[0027] In one embodiment, for the above-mentioned clamping assembly 2, the clamping assembly 2 includes an installation cavity 201 installed at the bottom end of the crystallizer connecting frame 1, a motor 202 is arranged inside the installation cavity 201, a worm 203 is arranged on the output shaft of the motor 202, a limiting disc 204 is arranged on the outer side of the worm 203, and a rotating disc 205 is arranged inside the limiting disc 204; a plurality of clamping rods 206 penetrating the side wall of the limiting disc 204 are arranged on one side of the rotating disc 205, and a worm wheel 208 matching the worm 203 is arranged on the top of the rotating disc 205 through a connecting shaft 207; a through hole 209 matching the clamping rod 206 is opened at the bottom end of the limiting disc 204, and the plurality of through holes 209 are arranged in a cross shape; the rotating disc 2 A slide groove 210 that cooperates with the clamping rod 206 is provided on one side of 05 and on the outside of the connecting shaft 207, and the cross-section of the slide groove 210 is set to a square structure, a limiting ring 211 is set at one end of the circumferential side wall of the clamping rod 206, and a snap-on hook 212 is set at the bottom end of the clamping rod 206. Specifically, when in use, a magnet may be provided inside the snap-on hook 212, and a snap-on groove and a magnet that cooperate with the snap-on hook 212 are provided inside the crystallizer 8, so that the overall device can be fixedly connected to the water inlet section of the crystallizer 8 through the snap-on hook 212, ensuring that the crystallizer 8 will not shake during vibration, reducing wear and damage caused by equipment movement or frequent adjustments, extending the service life of the equipment, and reducing maintenance costs.
[0028] The working principle of the clamping assembly 2 is as follows: the motor 202 is started through an external controller to drive the worm 203 to rotate, and the worm wheel 208 is driven to rotate under the meshing action of the worm 203 and the worm wheel 208, thereby driving the connecting shaft 207 to rotate, and then driving the rotating disk 205 to rotate. Under the action of the perforation 209 and the limit ring 211, the clamping rod 206 is driven to slide in the slide groove 210 under the rotation of the rotating disk 205, and the end of the clamping rod 206 is moved from the middle of one side of the slide groove 210 to the corner of the slide groove 210, so that the distance between the clamping rods 206 is increased. After the distance is increased, the clamping hook 212 at the bottom of the clamping rod 206 is inserted into the clamping groove of the crystallizer 8 that cooperates with it, thereby realizing the fixed connection between the overall device and the crystallizer 8.
[0029] In one embodiment, for the above-mentioned control and adjustment component 4, the control and adjustment component 4 includes a fixed frame 401 installed on the top of the crystallizer connecting frame 1, and a limit frame 402 is arranged on the top of the fixed frame 401, and the limit frame 402 is a U-shaped structure, and abutment block 403 is arranged on one side of the limit frame 402; a threaded rod 404 is arranged on the other side of the limit frame 402 through a through hole, and a knob 405 and a limit plate 406 are respectively arranged on both sides of the threaded rod 404, so that the scale 5 can be fixed under the action of the threaded rod 404 and the limit plate 406, thereby eliminating the problem of displacement of the scale 5 caused by vibration of the crystallizer 8, human collision or improper operation, avoiding the situation where the measurement is interrupted due to displacement of the scale 5 and the need for adjustment or recalibration, thereby ensuring the accuracy of the protective slag thickness measurement.
[0030] The working principle of the control and adjustment component 4 is as follows: the staff passes the scale 5 through the crystallizer connecting frame 1, connects one side of the scale 5 to the abutment block 403, and then manually turns the knob 405. Under the rotation of the knob 405, the threaded rod 404 is driven to rotate, thereby connecting the limit plate 406 to the other side of the scale 5 until the two are in contact and stop turning.
[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0032] In practical applications, such as Figure 6As shown, the staff places the whole device at the crystallizer 8 and uses the clamping assembly 2 to connect the crystallizer connecting frame 1 and the crystallizer 8 to be adsorbed on the water inlet section of the crystallizer 8. It should be noted that the crystallizer 8 is provided with a clamping groove and a magnet that cooperates with the clamping assembly 2. The crystallizer connecting frame 1 vibrates with the crystallizer 8 without shaking. After the installation is completed, the scale 5 is placed at the crystallizer connecting frame 1 and moved downward until the asbestos circular plate 6 at the bottom of the scale 5 contacts the top of the protective slag 10. The top position of the protective slag 10 is recorded by the reading of the scale 5, and then the measuring wire 7 is passed through the scale 5 and moved downward. The measuring wire 7 moves downward to contact the position of the molten steel 9 and the protective slag 10. After staying for a preset time, the measuring wire 7 is taken out. The measuring wire 7 is in the position of the protective slag 10 and remains intact because the melting point temperature is not enough, and the measuring wire 7 in contact with the molten steel 9 will be melted, so the bottom position of the protective slag 10 can be obtained according to the measuring wire 7, so that the total thickness of the protective slag 10 can be obtained using the top position and bottom position of the protective slag 10.
[0033] In summary, with the help of the above technical scheme of the utility model, the utility model has a simple structure, is easy to use, has no safety risks, is simple and adjustable without changing the original continuous casting operation habits, and can be used for measuring and marking the thickness of protective slag 10 under different steel grades and different liquid levels, which is convenient for real-time operation by operators on the production site. The utility model sets a snap-on assembly 2 so that the overall device can be fixedly connected to the water inlet section of the crystallizer 8 through a snap-on hook 212, ensuring that the crystallizer 8 will not shake during vibration, reducing wear and damage caused by equipment movement or frequent adjustments, extending the service life of the equipment, and reducing maintenance costs. The utility model sets a control and adjustment assembly 4 so that the scale 5 can be fixed under the action of the threaded rod 404 and the limit plate 406, thereby eliminating the problem of displacement of the scale 5 caused by vibration of the crystallizer 8, human collision or improper operation, avoiding the situation where the displacement of the scale 5 causes measurement interruption and requires adjustment or recalibration, and ensuring the accuracy of the protective slag thickness measurement.
