[0002] The ladle is the most important tool in the pouring process. The erosion of the refractory bricks in the ladle is closely related to the quality and safety of the pouring process.

[0003] Although the size of the refractory bricks used in the ladle are consistent during the laying process, the erosion depths at different positions in the ladle are different after refining, and the refractory bricks have a certain slope during the laying process. Simply using measuring tools in the ladle cannot accurately understand the actual erosion conditions at different positions in the ladle. Therefore, a tool that can accurately measure the erosion depth of the ladle refractory material at multiple positions is needed.

[0004] In the prior art, the refractory lining thickness measuring device for electric furnaces and molten iron ladles disclosed in Chinese patent CN210220907U has a relatively complex structure and a relatively high manufacturing cost; it can only test the refractory thickness of a fixed depth and cannot measure the actual thickness of the ladle at different depths at multiple positions. In this regard, the following improved technical solution is proposed. Utility Model Content

[0018] The following will be combined with the attached embodiment of the utility model Figure 1-2 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] A ladle refractory corrosion measuring tool comprises a scale 1.

[0020] In the above embodiment, as a preferred embodiment of the utility model, the scale 1 is a scale with a round tube structure. The scale with a round tube structure is lighter in weight and more convenient to slide the position of the vernier scale 3 than a square scale, and the sliding fit accuracy is higher.

[0021] The middle of the scale 1 is vertically connected to the measuring base 2; the measuring base 2 is used for supporting, positioning and clamping the tool on the top plane of the ladle 6.

[0022] In the above embodiment, as a preferred embodiment of the utility model: the measuring base 2 is composed of a slider I2-1 and a base pad 2-2. The slider I2-1 is slidably mounted in the middle of the scale 1; it is used to adjust the specific position of the entire measuring base 2. In addition, the base pad 2-2 can be composed of a vertical portion and a horizontal portion and has a horizontal bottom surface; the horizontal bottom surface fits closely with the top plane of the ladle 6 (such as Figure 1 As shown), it is used for supporting, positioning and clamping the tool of the utility model on the top plane of the ladle 6.

[0023] The two ends of the scale 1 are respectively slidably adapted to install the vernier ruler 3, and the left and right oil dipsticks 3 are used to measure the actual thickness of the ladle 6. To ensure the measurement applicability and versatility: the bottom of the vernier ruler 3 is installed with a measuring claw 4 that can be vertically extended and can mark the length of vertical extension; through the adjustment of the extension displacement of the measuring claw 4, it is used to test the wall thickness of the ladle 6 at different depths. It should be noted that: when in use, the extension length of the two measuring claws 4 must always be kept consistent.

[0024] The bottom end of the measuring claw 4 is vertically fixed with a horizontally arranged tip 5; the tip of the tip 5 faces inward. The position of the measuring claw 4 is positioned by the tip of the tip 5, so that the tip of the tip 5 is pressed against the inner and outer walls of the part to be measured of the ladle, and the use is not affected when the inner and outer walls of the ladle are inclined.

[0025] The tip of the tip 5 is vertically coplanar with the inner vertical end surface 3-4 of the vernier scale 3, so as to ensure that the scale value of the right oil dipstick 3 minus the scale value of the left oil dipstick 3 is exactly the actual wall thickness value at the depth position of the ladle 6. Then, the inner and outer wall width values ​​of the new unused ladle 6 are subtracted from the actual wall thickness value to calculate the erosion depth of the ladle.

[0026] In the above embodiment, as a preferred embodiment of the utility model: the scale 1 is provided with graduation lines starting from 0 from left to right, so as to facilitate obtaining the actual wall thickness value by subtraction, which has been described above and will not be repeated here.

[0027] In the above embodiment, as a preferred embodiment of the utility model: the oil dipstick 3 has a slider II3-1; the slider II3-1 is slidably adapted and installed on the outside of the scale 1; it is convenient to slide and adjust the position of the left and right oil dipsticks 3, and then it is convenient for the tip 5 to press against the inner and outer walls of the ladle 6 to be tested.

[0028] The bottom end of the slider II 3-1 is vertically fixedly connected to the top of the measuring claw 4; the measuring claw 4 is a sleeve structure 3-2; the bottom of the measuring claw 4 of the sleeve structure 3-2 is coaxially pulled and adapted to install the pull rod 3-3; in order to increase the friction resistance and prevent the pull rod 3-3 from changing its position after adjusting the position, a friction resistance sleeve is added between the pull rod 3-3 and the sleeve structure 3-2, and the friction resistance sleeve is a non-metallic structure, and the other parts are all metal structures. The bottom end of the pull rod 3-3 is vertically fixedly installed with a horizontally set top 5.

[0029] In the above embodiment, as a further improved embodiment of the utility model: to ensure that the extended lengths of the left and right pull rods 3-3 are consistent with each other on the left and right, so as to test the wall thickness of the ladle 6 of the same depth: the pull rod 3-3 is provided with a scale, so that the extended length of the pull rod 3-3 can be measured and used consistently.

[0030] The working principle of the utility model is as follows: the utility model supports the measuring base 2 on the top plane of the ladle 6; then slides the displacement vernier 3 left and right, and pulls the pull rod 3-3 of the vernier 3 to a fixed length, so as to measure the wall thickness of the ladle 6 at a fixed depth; the vernier 3 is stopped after the tip of the top 5 touches the inner and outer walls of the part to be measured of the ladle 6, and finally the scale value of the right vernier 3 is subtracted from the scale value of the left vernier 3 to obtain the actual thickness of the refractory material after erosion of the part of the ladle 6. Finally, the inner and outer wall width values ​​of the brand new and unused ladle 6 are subtracted from the actual wall thickness value of the ladle after erosion, and the erosion depth of the ladle can be calculated.

[0031] From the above description, it can be found that the utility model has the advantages of simple structure, low cost and convenient adjustment. In particular, it can measure the actual wall thickness after erosion of any part of a steel ladle of different depths, inclined surfaces and different thicknesses, has a wide measuring range and excellent versatility.

[0032] To sum up, the utility model solves the technical problem that the existing measuring tools have relatively high production costs and cannot achieve adaptive adjustment for thickness measurements at different depths; the tool has a simple overall structure, low production costs, and is easy to adjust and use. In particular, it can achieve actual wall thickness measurements at different depths and slopes, has a wide measurement range, excellent versatility, and is suitable for promotion.

[0033] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
