In a collaboration with the Moldavian Metallurgical Plant, VNIIMETMASh has used the results of studies of the design elements of continuous-caster molds to develop and succesfully produce a new liner for such molds - the VM-sinus. The main feature of this liner is the presence of convexity on the central sections of its walls. The convexity makes it possible to center the solidifying skin of the casting inside the liner when the skin is just beginning to form. Gradual straightening of the sinusoidal sections of the skin minimizes the size of the gas-filled gap between the skin and the walls of the liner. Gap size is minimized not only along the surfaces of the liner, but also at the corners. The new liners are being made at the pilot plant operated by VNIIMETMASh.
