"Set of male hub for use in a casting operation with pressure of bottom and methods of assembling a set of male of cube and merge one object".It is provided a method of merging an object, usually a wheel for railroad.A graphite mold which has a section of the bottom box and a section of the upper box has an opening in the section of the bottom box that allows metal is fed upward by pressure.In the cavity of the cast object. A set of buffer rod extends through openings located centrally in the section of the upper box and lower box section.The male hub in the opening section of the saddle in the bottom box by interruption of the casting so as to maintain the molten metal in the cavity in the mold.The number of male of cube is composed of refractory material to the metal makes contact, thereby enabling the reuse of the set of male of the cube.
