Description

Technical Field

[0001] The utility model relates to an improvement of a crystallizer inner cavity measuring device, belonging to the technical field of measuring tools in the metallurgical industry, in particular to a manual measuring device for the inner cavity bottom length of a crystallizer. Background Art

[0002] In the metallurgical industry, the crystallizer is a common equipment used for continuous casting of slabs, large-section square billets and special-shaped billets. It includes an outer frame, two wide plates in the length direction, and two narrow plates between the two wide plates. Each narrow plate is provided with an adjustment device. By adjusting the spacing and inclination between the two narrow plates, the size of the inner cavity of the crystallizer can be adjusted online; such as a crystallizer with a specification of 200*1550, the crystallizer height is 900㎜.

[0003] With the increasing demand for steel products in the market, product specifications are becoming more and more refined, and customers are increasingly demanding the utilization rate of steel strips. This requires steel manufacturers to adjust the inner cavity size of the crystallizer in a timely manner to adapt to the production of ingots. Since the crystallizer is used online for a long time, the sensitivity of the adjustment device will also change, and the spacing and inclination between the two adjusted narrow plates will also have errors, which cannot meet the adjustment requirements of the inner cavity size of the crystallizer. Therefore, it is necessary to measure and verify the spacing length between the two adjusted narrow plates. The current measurement method is for the staff to measure manually with a ruler. It is easy to measure between the upper ends of the two narrow plates, but the lower ends of the two narrow plates are located at the bottom of the inner cavity of the crystallizer, which is deep and has a small space. It is difficult to measure and is more prone to measurement errors. Summary of the invention

DETAILED DESCRIPTION

[0013] Reference Figure 1 Make this utility model.

[0014] The manual measuring device for the inner cavity bottom length of a crystallizer comprises a sleeve 1, a left vertical pipe 3, a right vertical pipe 16 and a push-type air pump 17. The left vertical pipe 3 and the right vertical pipe 16 are fixedly provided at both ends of the sleeve 1, respectively. The upper end of the left vertical pipe 3 is provided with an upper cover 8, and the upper end of the right vertical pipe 16 is fixedly provided with a push-type air pump 17. The air outlet of the push-type air pump 17 is connected to the inner cavity of the right vertical pipe 16, and a deflation valve 18 is fixedly provided on the side wall of the right vertical pipe 16. It is characterized in that: a slide ruler 2 is provided in the cavity of the sleeve 1, the front end of the slide ruler 2 passes through the matching central hole at the front end of the sleeve 1, and the rear end of the slide ruler 2 is fixedly provided with a slider 10 that is sealed and matched with the inner wall of the sleeve 1. The rear port is connected and fixed with a threaded plug 12; the inner cavity of the right vertical pipe 16 is connected with the inner cavity of the sleeve 1 through the through hole 19 on the side wall of the sleeve 1; a sliding column 4 is slidably provided in the cavity of the left vertical pipe 3, and a rubber pad 9 is fixed at the lower end of the sliding column 4. The lower end of the inner cavity of the left vertical pipe 3 is connected with the front end of the inner cavity of the sleeve 1, and the rubber pad 9 is in contact with the slide 2. A spring 6 is provided between the upper end of the sliding column 4 and the upper cover 8. A connecting rod 5 is fixed in the middle of the upper end of the sliding column 4. After the upper end of the connecting rod 5 passes through the central holes of the spring 6 and the upper cover 8, it is connected and fixed with the pull ring 7. Under the elastic action of the spring 6 itself, the sliding column 4 is pressed down, so that the rubber pad 9 is pressed tightly on the slide 2 to prevent the slide 2 from sliding at will.

[0015] A fixed sealing ring 13 is provided around the inner end of the thread plug 12 to seal the thread plug 12 and the inner wall of the sleeve 1 .

[0016] A sliding sealing ring 11 is fixedly provided around the slider 10 to seal the slider 10 against the inner wall of the sleeve 1 .

[0017] The length of the sleeve 1 is 1000 mm.

[0018] The side wall of the slide rule 2 is provided with scales, and the length of the slide rule 2 is 700-800 mm.

[0019] The upper ends of the left vertical pipe 3 and the right vertical pipe 16 are connected and fixed by a fixing rod 14, and a handle 15 is fixedly provided on the fixing rod 14. The length of the left vertical pipe 3 and the right vertical pipe 16 is 800-900 mm.

[0020] The center line of the sleeve 1, the center line of the left standpipe 3 and the center line of the right standpipe 16 are located in the same plane.

[0021] When the utility model is used to measure and check the inner cavity of the crystallizer, the spacing length between the two narrow plates at the upper opening of the inner cavity of the crystallizer can be measured with a ruler; the spacing length between the two narrow plates at the bottom of the inner cavity of the crystallizer needs to be measured using the utility model. During measurement, the operator holds the handle 15 and places the sleeve 1 at the bottom of the inner cavity of the crystallizer, so that the rear end of the sleeve 1 is close to a narrow plate, lifts the pull ring 7, and repeatedly presses the push-type air pump 17. The gas enters the inner cavity of the right vertical pipe 16, and then enters the cavity of the sleeve 1 through the through hole 19, pushing the slider 10 and the slide ruler 2 to move forward until the front end of the slide ruler 2 is against another narrow plate; at this time, the pull ring 7 is released, and the slide column 6 and the rubber pad 9 slide downward under the action of the spring 6, so that the rubber pad 9 is pressed against the slide ruler 2 to prevent the slide ruler 2 from hitting the side wall of the narrow plate and shrinking during the process of lifting the sleeve 1 upward; before lifting the sleeve 1, the air release valve 18 is opened first to release the pressurized gas in the cavity of the sleeve 1 to prevent the pressurized gas from continuing to push the slide ruler 2 during the process of lifting the sleeve 1 upward. After taking out sleeve 1, read the scale value on slide ruler 2, and add the fixed length of sleeve 1, which is the actual measured length of the distance between the two narrow plates at the bottom of the inner cavity of the crystallizer. Compare this actual measured value with the set value of the crystallizer. If they are the same, it means that the crystallizer can be used normally. If they are different, it is necessary to use the zeroing mode of the crystallizer for adjustment.
