| 201 | Method of positioning components of a centrifugal casting machine for a mold stripping operation | US2416 | 1979-01-10 | US4203483A | 1980-05-20 | Frederick W. Baumann; Bernard C. Kaczkowski |
| A positioning apparatus for a centrifugal casting machine having an articulated mold that is mounted for rotation in a cantilevered manner on a drive shaft. The positioning apparatus includes a pair of pillow block bearings having arcuate bearing races that operate to allow the drive shaft to be tilted within a predetermined angular range relative to its longitudinal axis. In addition, the positioning apparatus includes a plurality of locking pins each of which are mounted to cooperate respectively with one of a plurality of positioning members mounted on a rotatable mold-supporting face plate of the casting machine. Operation of the lock pins into engagement with the positioning members moves the face plate into a predetermined position relative to its axis of rotation, following a casting cycle of the machine, so that segments of the centrifugal mold can be radially stripped from an article cast therein without unduly distorting the cast article. Pursuant to the preferred method of the invention the drive shaft of a centrifugal casting machine is rotated about its longitudinal axis while the shaft is tilted within a predetermined angular range relative to a horizontal plane to perform a casting operation. Following the casting cycle, the drive shaft and rotatable casting mold of the machine are raised to a predetermined position of alignment above the tilted position of the shaft during the casting cycle, in order to position the mold for easy removal of mold segments from an article cast therein. | ||||||

| A method for promoting the flow of a solidifiable liquid or molten material upon the surfaces of a body and particularly such a method applied to a process of rotational casting or molding requiring charging a mold cavity with the solidifiable liquid or molten material and rotating the mold about each of two mutually inclined axes with a speed that is progressively decreased substantially in accord with the progressive increase in viscosity of the solidifiable material. | ||||||

| A method for rotary casting of austenitic stainless steels. When rotarily cast, steel ingots are likely to crack on the surface. In order to prevent cracking, it is desirable to adjust the Nickel balance to within a certain value. In stopping the rotation, ghost rings can be prevented by a gradual deceleration of the speed of rotation.

| 206 | Casting process for rolls | US3670800D | 1969-06-02 | US3670800A | 1972-06-20 | VOS JACQUES DE |
| The invention consists of a method for making solid rolls, for example, metal working rolls, wherein a cylindrical shell comprising the roll working surface is first centrifugally cast in a horizontal cylindrical mold having removable end plates, and as soon as the shell has solidified, the end plates are removed, the mold containing the hot solidified cylindrical shell is mounted between two journal molds to form a complete roll mold, and metal of suitable composition is cast in the mold whereby there is formed a solid roll core which is metallurgically bonded to the said hollow shell and has integrally formed journal portions extending beyond the cylindrical shell.
