Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of continuous casting equipment, and specifically relates to an immersed nozzle centering device. Background Art
[0002] During the continuous casting process, in order to ensure the stability of the molten steel flow field in the crystallizer, the submerged nozzle inserted into the crystallizer needs to be aligned. The alignment accuracy of the submerged nozzle directly affects whether the molten steel flow field in the crystallizer is symmetrical and whether the thickness of the primary billet shell is uniform. When the thickness of the primary billet shell is uneven, stress concentration will occur due to different solidification shrinkage, resulting in crack defects on the surface of the continuous casting billet; when the thickness of the primary billet shell is less than the critical value, the continuous casting billet will bulge or even leak steel after leaving the crystallizer. Therefore, nozzle alignment is one of the important factors affecting the quality of the billet;
[0003] The submerged nozzles in continuous casting flow through high-temperature molten steel, creating a complex environment. Existing measurement and calculation methods make it difficult to accurately determine the nozzle's centering. Currently, the alignment of submerged nozzles in continuous casting production sites is typically determined by visual inspection and judgment based on experience, which is prone to errors. Existing techniques also use centering plates for alignment. However, because the measurement point is far from the operator, some workers with limited arm length cannot reach the plate above the submerged nozzle for measurement. Furthermore, the submerged nozzle temperature is too high, and being too close can easily burn workers. Utility Model Content
