METHOD OF CENTRIFUGAL CASTING OF COMPLEXLY PROFILED PIECES WITH DIRECTIONALLY ORIENTED STRUCTURE Russian patent published in 1997 - IPC

FIELD: foundry, in particular, centrifugal casting of complexly profiled pieces of high-temperature alloys. SUBSTANCE: the method consists in casting of melt in a rotatable mould heated to a temperature above the liquids and cooled and cooled on the end face, melt casting is performed by portions at time intervals; the mould areas above the free surfaces of the cast melt shifted to the axis of rotation are additionally heated up to the arrival of a new portion, after which heating is stopped, and the angular velocity of mould rotation is increased after casting of the next portion; each area of the mould is additionally heated to a temperature exceeding the preheating temperature by 5 to 50 C. EFFECT: facilitated procedure. 2 cl
