ANALYSIS AND TREATMENT OF CYLINDER ABNORMAL CLAMPING IN SLAB CRYSTALLIZER
The crystallizer of Tangshan Iron and Steel 1 600 mm double strand slab continuous casting machine has dynamic width adjustment function.Running the width adjustment system in calibration mode resulted in abnormal movement of the crystallizer clamping cylinder and corner cracks at the lower mouth of the crystallizer,which could not meet the accuracy requirements and affect production quality,posing a great safety risk.By analyzing the main equipment and functions of the crystallizer,the reasons for the abnormal clamping position of the crystallizer were identified.Through hydraulic system testing and inspection of chain control,the problem of abnormal clamping of the crystallizer was solved,hidden dangers were eliminated,and the long-term stable operation of the crystallizer was ensured.
