Description

TECHNICAL FIELD

[0001] The utility model belongs to the casting billet spray corrosion test technical field, more specifically, it relates to a kind of casting billet spray corrosion testing device. BACKGROUND

[0002] The quality of casting billet directly affects whether qualified molten steel can be converted into qualified products, and the casting billet macroetching experiment is an important means to detect the internal quality of casting billet, which plays a key role in guiding the production and maintenance of casting machine. The current casting billet corrosion adopts manual mode, and the corrosion tank is of concrete structure. The corrosion process is as follows: evenly sprinkle the cold etching liquid on the sample detection surface in the pickling tank, retain for 3-5 minutes, then brush with a brush, the corner part of casting billet can be wiped with a dry towel, so that the cold etching liquid fully corrodes the detection surface, then wash the detection surface with clean water, repeat 2-4 times, then blow dry the detection surface of casting billet with compressed air until the macrostructure of casting billet is clearly displayed. During the whole corrosion process, the operator covers the corrosion liquid on the surface of casting billet by spraying, and the tester cannot leave. This corrosion process is open type, which not only wastes time in waiting, but also easily inhales acid gas, and there is a safety risk of acid liquid splashing. The disadvantages of manual operation mode have not been effectively solved.

[0003] Therefore, the disadvantages of the prior art are: 1) manual application of corrosion liquid, which has the disadvantages of uneven application of corrosion liquid, uneven corrosion time, poor corrosion effect, corrosion liquid cost, etc. The sample is easy to turn yellow and dark after washing, which affects the accuracy of test results, especially for samples with high quality requirements, the current corrosion device cannot meet the requirements. 2) long time "guard" beside the corrosion tank to inhale acid gas, which affects health. During the original macrotest process, personnel must be beside, and the corrosion is open type and extensive operation, so the operator will inhale acid gas and affect health. In addition, with the extension of time, the equipment in the room will also be corroded to different degrees, affecting the use of equipment. 3) the corrosion tank is of concrete structure, and its anti-leakage performance becomes worse and worse with time, and the anti-collision performance is not strong. 4) the corrosion liquid can only be used once and cannot be reused, which causes waste.

[0004] Existing technology includes a method for optimizing the arrangement of flat nozzles for continuous casting, published under publication number CN112517867B. This method comprises the following steps: a. determining the working pressure setting value of the nozzle; b. conducting water distribution tests on a single nozzle; c. determining the water metering width; d. calculating the water volume ratio between the overlapping area of ​​adjacent nozzles and the central area of ​​a single nozzle; e. calculating the water volume ratio between the edge area and the central area for different nozzle heights and spacings; f. determining the optimal nozzle arrangement. This invention, based on cold-state performance testing of nozzles and combined with actual continuous casting process data, determines the optimal nozzle configuration method under different operating conditions. This method is simple and easy to implement, and the obtained nozzle configuration scheme has a high degree of conformity with the actual continuous casting process. It can improve the lateral cooling uniformity of the continuously cast billet, reduce the probability of quality defects such as cracks and bulging, and improve the quality of the continuously cast billet. This technology does not address the technical problems and solutions of this application. Utility Model Content
