The invention discloses an online centering adjustment method for a slab continuous casting crystallizer, which comprises the steps of construction preparation, crystallizer hoisting in place, crystallizer center line detection, crystallizer elevation detection, crystallizer levelness detection, going to the next step when the requirement is met or returning to analyze and process when the requirement is not met, crystallizer online centering measurement, finishing online centering when the requirement is met, returning to analyze and process when the requirement is not met, and finishing crystallizer online centering. The method is rigorous in process and reasonable in data analysis, online centering can be rapidly adjusted, the online centering adjustment precision of the slab continuous casting crystallizer is guaranteed, a reference is defined for online arc alignment of the fan-shaped section, the safety risk caused by construction is reduced, the construction difficulty is reduced, and the construction period is effectively shortened.
Description
technical field [0001] The invention relates to the technical field of metallurgical construction, in particular to an online centering adjustment method of a slab continuous casting crystallizer. Background technique [0002] Continuous casting technology has significant advantages such as greatly improving metal yield and slab quality, saving energy and reducing consumption, and has been widely adopted by iron and steel enterprises. The crystallizer is the most critical component in the continuous casting equipment and the heart of the continuous casting machine. Mold performance plays a vital role in improving the continuous casting productivity, maintaining the normal production of the continuous casting process, and ensuring the quality of the slab. The poor alignment accuracy of the current crystallizer on-line will cause the position of the wide-side foot roll to shift and cause non-rotation, which not only loses the original function of the roll, but also scratches ...
