[0002] In the normal production of continuous casting in steelmaking, checking whether there are small defects in the corner of the billet is an essential part of the continuous casting work. However, since the surface of the corner specimen after flame cutting is often covered with impurities such as scale, it is impossible for inspectors to visually detect the existence of defects with the naked eye. Therefore, after the corner of the continuous casting billet is flame cut, the specimen needs to be pickled with hydrochloric acid of a certain concentration and then inspected.
[0003] However, during the entire pickling test operation process, due to the combined action of high temperature and hydrochloric acid on the billet corner specimen, a certain amount of pungent and harmful gas will be volatilized. Long-term specimen work will cause certain harm to the bodies of test personnel; moreover, when collecting the liquid after the experiment, manual pouring of the pickling liquid may pose a risk of splashing; at the same time, during the entire test process, the pickling operation is not only cumbersome but also poses potential safety hazards. How to effectively improve the pickling specimen operation process and the test environment, not only avoid the volatilization of harmful gases, but also effectively collect and process the liquid after the experiment is particularly important. Content of the Utility Model

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0021] As Figure 1 shown, a novel pickling device for billet corner specimens is disclosed in this embodiment, which includes a pickling device box body 1 and a specimen clamp 12. A box door 8 is provided on the pickling device box body 1. A horizontally arranged partition 10 is provided inside the pickling device box body 1. A pickling vessel 5 is provided above the partition 10. A liquid discharge device 7 is provided at the bottom of the pickling vessel 5. The liquid discharge device 7 includes a downcomer 7-1. The downcomer 7-1 is provided at the bottom of the pickling vessel 5, and a drain valve 7-2 is provided on the downcomer 7-1.
[0022] A bottom track 6 is provided on the partition 10. A sliding rail 11 in sliding fit is provided on the bottom track 6. The pickling vessel 5 is detachably provided on the sliding rail 11. The pickling vessel 5 is connected to the sliding rail 11 and pulled out for placing a billet corner specimen in the pickling vessel 5. After placing, the pickling vessel 5 is pushed above the partition 10, and then the box door 8 is closed.
[0023] In this embodiment, rollers 13 are provided at the bottom of the pickling vessel 5. The rollers 13 are arranged on the sliding rail 11, and a limit block is provided at the end of the sliding rail 11 to prevent the rollers 13 from falling out. After opening the box door 8, the sliding rail 11 is pulled out to the outside of the box body 1, and the pickling vessel 5 can be removed from the sliding rail 11 and carried to the ground, and then moved to the cleaning area for cleaning by means of the rollers 13 of the pickling vessel 5.
[0024] A plurality of waste liquid collection vessels 9 are provided below the partition 10. The waste liquid collection vessels 9 are provided below the outlet of the downcomer 7-1 of the liquid discharge device 7. Align the waste liquid collection vessel 9 below the outlet of the downcomer 7-1, and open the drain valve 7-2 to discharge the liquid after the pickling experiment into the waste liquid collection vessel 9, which is convenient for centralized treatment of the waste liquid.
[0025] An exhaust gas collection device 2 and a water source pipe 3 are provided on the top plate of the pickling device box body 1. The air inlet of the exhaust gas collection device 2 is provided above the pickling vessel 5. The exhaust gas collection device 2 is an exhaust pipe with a flared air inlet end and is connected to an external induced draft fan for centralized collection of toxic and harmful gases. The water outlet of the water source pipe 3 passes through the top plate of the pickling device box body 1 and extends above the pickling vessel 5. A water pipe valve 4 is also provided on the water source pipe 3.
[0026] The use process of the present utility model is as follows:
[0027] During use, open the door 8 of the pickling device box body 1, open the water pipe valve 4 installed on the water source pipe 3, put a certain amount of water in the pickling vessel 5, pull out the pickling vessel 5 along the bottom track 6 to a certain position, pour hydrochloric acid liquid in a certain proportion, use the specimen clamp 12 to put the billet corner specimen into the pickling vessel 5, and push the pickling vessel 5 back to its original position, then close the two side doors 8 and wait for the specimen to undergo pickling reaction. The pickling harmful gases generated during the reaction are centrally collected and processed by the waste gas collection device 2, avoiding the unorganized emission of harmful gases. When the pickling test for a certain period of time is over, pull out the pickling vessel 5 along the bottom track 6, and use the specimen clamp 12 to take out the specimen. After repeating this many times, if pickling is no longer required, open the drain valve 7-2 to centrally collect the pickled waste liquid into the waste liquid collection vessel 9 for centralized treatment.
[0028] On the one hand, the present utility model adds a push-pull track and rollers 13 at the bottom of the pickling vessel 5, which facilitates the operation of personnel. An exhaust gas collection device 2 is added to the top of the pickling device box body 1 to avoid the unorganized emission of harmful gases during pickling tests. More importantly, the centralized collection of pickling waste liquid is realized, eliminating the need for manual pouring of pickling waste liquid by personnel for collection and avoiding safety accidents.
[0029] The embodiments described above are only descriptions of the preferred modes of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
