The eccentricity of the piston in the continuous casting machine cannot be ignored, which not only increases the internal leakage of the hydraulic cylinder, but also increases the friction on the surface of the friction pair, and even has serious consequences such as deformation failure. In this work, the biomimetic micro‐texture technology is used to construct the microtextures on the surface of the cylinder so that it produces a continuous centring force during operation, and the problem of piston eccentricity is corrected. Moreover, the influence of hydraulic cylinder operating parameters and biomimetic microtexture parameters on the dynamic pressure support force is also analysed. This has a very positive effect on improving the response frequency of the hydraulic cylinder and the working efficiency of the hydraulic system.
