Description

Technical Field

[0001] This utility model relates to the field of nozzle model measurement technology, specifically a measuring ruler for the nozzle model of the curved section of an arc continuous casting machine. Background Technology

[0002] Our slab continuous casting machine is an arc-shaped continuous casting machine. The secondary cooling section of the arc-shaped continuous casting machine is divided into three zones: Zone 2, Zone 3, and Zone 4. The secondary cooling nozzles for each zone are 6.0, 5.0, and 4.0 respectively, totaling 204 nozzles. The three nozzle types are identical in appearance, differing only in length by 10-20mm. It is extremely easy to install the wrong type during installation. The correctness of the nozzle types in different zones of the arc section has a significant impact on slab quality and production safety. Therefore, a thorough check of the nozzle types in the arc section must be performed before each replacement. Previously, the method for checking the nozzle types was for operators to scrape off the scale on the nozzle heads with a wire and then directly inspect the nozzle heads. The method of manually checking nozzle model markings is cumbersome and inefficient, and the model markings are difficult to see due to the angle of most nozzles, resulting in poor operability and low accuracy. To address this, a measuring ruler for nozzle model markings in the curved section of an arc-shaped continuous casting machine (see patent number: 201821891597.3) is proposed. It includes a positioning plate for fitting tightly against the nozzle outlet and a measuring tube connected to one side of the positioning plate. The measuring tube is provided with several model markings, and the distance between the model markings and the positioning plate is equal to the length of the corresponding model nozzle. This invention solves the problems of low efficiency and poor accuracy caused by manually checking nozzle model markings, and greatly improves the uniformity of secondary cooling in the curved section.

[0003] However, the measuring rulers for the curved section nozzles of some existing arc continuous casting machines on the market are generally quite long, making it difficult to pick up and store the device and inconvenient to use. At the same time, the device cannot be angled, and it cannot quickly perform measurement work when encountering some extreme usage angles, resulting in poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing measuring rulers for the curved section nozzles of arc continuous casting machines, which are generally too long, making it inconvenient to pick up and store, and also unable to adjust the angle. In some extreme usage angles, they cannot be quickly measured, resulting in poor practicality. Therefore, this utility model provides a measuring ruler for the curved section nozzles of arc continuous casting machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring ruler for the nozzle model of the curved section of an arc-shaped continuous casting machine, comprising:

[0009] As a further improvement of this utility model, both sets of fixing holes are provided with fixing screws inside.

[0010] As a further improvement of this utility model, both the upper and lower measuring rods are provided with model markings on their exteriors.

[0011] As a further improvement of this utility model: both sets of chucks are provided with locking teeth inside, and both sets of chucks are connected to each other by locking teeth and knobs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the device is installed by inserting the upper and lower measuring rods into the corresponding upper and lower connecting frames, respectively, and connecting and fixing them through fixing holes, fixing screws, connecting holes, and fixing grooves. Then, the operating angle is adjusted by connecting the two sets of chucks with a knob, adjusting the operating angle of the measuring rod, and tightening the knob to make the chuck teeth inside engage and fix it, thus completing the adjustment work.
