The operation of continuous casting machines (CCM) is associated with shifting of the casting channel geometry due to equipment wear and the imperfections of traditional casting methods. An improved combined technology for monitoring and adjusting the position of CCM equipment is presented. The proposed approach integrates high-precision real-time geodetic measurements with mathematical modeling of the machine’s process axis. A mathematical model of the continuously formed cast ingot’s trajectory has been developed, enabling the calculation of optimal roller motion vectors in the secondary cooling zone to minimize positional deviations. Software implementing algorithms for rational equipment alignment is presented. Particular attention is paid to the metrological certification of process templates, which demonstrated their actual radial deviations of up to ±15 mm. The results of industrial testing of the technology on billet and slab continuous casters from various manufacturers are presented, confirming an increase in equipment positioning accuracy to 0.1–2.0 mm and a reduction in repair time by 2–3 times. A combined approach, including periodic geodetic alignment and real-time adjustments using verified templates, reduces the incidence of continuously cast billets defects by 40–50 %.
