    Abstract: A tilting centrifugal casting machine for producing a compound solid roll by centrifugally casting the outer shell and inner layer into an integral structure. The angle of inclination of the axis of rotation of the mold and the angle defined by the line connecting the center of the mold and the center of the rollers relative to the horizontal are selected to be within the optimum ranges, thereby to obtain a tilting type of centrifugal casting machine with high anti-vibration effect and safety in use, capable of producing a defect-free superior compound solid roll.

    Abstract: A vibration-preventive centrifugal casting apparatus. The apparatus includes a mold shell adapted to be rotated for centrifugal casting and a cylindrical liner of a novel construction which is fitted into the mold shell. The liner is designed so that its outer surface will be spaced a minute distance from the inner wall of the mold shell when fitted therein. The outer surface of the liner has an uneven configuration which will provide discontinuous contact with the inner wall of the mold shell when the liner is thermally expanded. The discontinuous contact serves to retard the transmission of heat from the liner to the shell by conduction.

    Abstract: A molten castable substance (as metals, glass, plastic, etc.) is continuously centrifugally cast to tube on a centrifuged lining of a heavier liquid mold material (examples of which are lead, tin, and Wood''s metal). The molten substance is continuously introduced into the starting end of the centrifugal casting machine and forms a molten, axially moving, cylinder on the liquid lining. The substantially solidified tube floats out of the bore at the opposite end of the casting machine on a lining of the liquid mold material and without contacting the solid portions of the machine''s exit orifice. The unrestricted floating of the tube out of the exit orifice is accomplished by decreasing the diameter of the tube in its molten state by applying a pressure differential between the liquid mold material and the gas internal to the tube being cast. The pressure differential is brought about by various methods as disclosed in the specification. Prior art methods for the continuous centrifugal casting of tube on a liquid mold lining depend on thermal shrinkage of the tube, as it cools in the mold, to permit egress from the machine. Due to the applied pressure differential, such thermal shrinkage to permit unrestricted exit of the tube does not have to be a requirement of the present invention and, as a result, product variability and casting rates can be greatly increased.

    Abstract: A highly automated method of centrifugally casting large diameter finned dynamoelectric machine frames is described utilizing a sectionalized mold which is automatically dismembered and reassembled subsequent to casting. The sectionalized mold is provided with large circular wheels at opposite ends of the mold and the wheels are placed atop substantially horizontal rollers which transmit rotary torque to the mold during centrifugal casting. Subsequent to casting, the mold is lifted vertically from the rollers and placed in a vertical disposition atop the arbor of a mold stripping machine whereafter sections of the mold are sequentially stripped from the cast (with the cast and stripped sections being rotated subsequent to the stripping of each section). The cast frame then is lifted from the arbor and the mold is reassembled by advancement of the stripping machine jaw to sequentially push the mold sections toward the arbor.
