The mold shaking table is the heart of continuous casting equipment, and its performance evaluation is the key to study the mold shaking table. In order to evaluate the dynamic performance of the crystallizer shaker, firstly, develops a dynamic real-time test system based on laser displacement to measure the overall movement process of the crystallizer shaker; secondly, the original displacement data is measured; afterwards, the displacement data is processed by data processing software to evaluate the vibration dynamic characteristics of the crystallizer shaker; finally, after the test method is implemented in the field and the test data are processed, the performance difference of the mold shaking table in the field under different casting speeds can be well evaluated, which provides guidance for the overhaul and maintenance of the mold in the field.
