In this contribution, a technique of axial centering of cast-iron moulds, e.g. the so-called “rail system” as suggested by KonCAD CZ s.r.o. for the application of horizontal centrifugal metal casting process, is described, evaluated, and finally not recommended for practical use. The proposed principle of the axial centering technique is based on the fact that on the cast-iron mould external perimeter there are welded, perpendicularly to the cast-iron longitudi-nal centreline, two rings the external shape of which is similar to the shape of the Vignole (flat-bottomed) rail. The cast-iron moulds are supported by two pairs of opposite conic roll-ers. The cast-iron mould is driven by a contact power transmission, i.e. by the friction meth-od employing a pair of conic rollers and acting over the welded rings to the cast-iron mould. The circumferential force transfer is carried out by the friction between the cast-iron mould rings and the two driving rollers. Both driving and driven rollers have similar shapes analo-gous to a tyred wheel profile. The two driving rollers are tightly fit on the common drive shaft, the centreline of which runs in parallel with the cast-iron mould longitudinal centre-line. Both driving and driven rollers have a similar shape as a tyred wheel profile. The neces-sity of creating of a sufficient thrust force of the cast-iron mould against the rollers causes wear conditions at the rounding of external shapes of rings, bearings, as well as roller con-tact conic surfaces.
