Abstract Leaking between the three split rollers of caster segment for the non-entire shaft roller has a serious influence on the surface quality of the slab and the costs of segment maintenance. In this study, the characteristics and reasons of leakage points section of the roller were analyzed, and the key point was obtained which is that how to ensure the synchronization of three split rollers and nonrigid connection between rollers. According to the analysis, the slider with a cross shaft coupling was confirmed. Practice proved that the scheme can perfect the solution of the three split rollers leaking problem, and greatly prolong the roller life, and improve the surface quality of slab.
