It is established that the defining factor of accuracy of the designing parameters of S-type billet continuous casting machine (CCM) is relative difference of curvature of the adjacent arc-like sections, which form process axis of strand. An analysis of the local radius change of CCM ingot path curvature is carried out. In the process of CCM equipment alignment, it is necessary to ensure alignment of its curvature centers under condition of curvature value equality for minimization of its relative difference. Developed technology of position control and CCM equipment alignment allows meeting this requirement. The developed technology is based on the use of “Vizir 3D” a high-precision measurement system built on the base of electronic total station. Practical experience of alignment showed the efficiency of geodesic and combined method of equipment alignment on both billet and slab CCM.
