Abstract：In order to extend the service life of the segment online and to improve the function of continuous casting machine precision and product quality， the analysis of influence of segment 400 mm thick slab continuous casting machine service life was achieved， such as the segment drive roller opening large， segment drive roller limit bolt cut， segment roll gap problem is high， and a lot of optimization methods to solve the above problems. It shows that： there are many factors influencing the service life of the continuous casting machine， and once finding out the main problems and solving them， the service life of the continuous casting machine can improved and the quality of billet also can be improved .
