ABSTRACT:
The method consists in that molten metal and slag are obtained in a reservoir and then are poured into a mold and kept there till crystallization of the metal takes place and a shaped casting is produced. Prior to the process of pouring, the mold is moved towards the reservoir so that their upper end faces adjoin each other to form a closed integrated unit, which is turned in a vertical plane to transfer the metal and slag into the mold. The joint of the mold with the reservoir in the process of pouring is tightened by providing a time delay for this process from the moment of covering the joint with a slag layer till the moment of solidification of this layer. In the device for producing the castings, the mold and reservoir are provided with individual drives rotating them in a vertical plane, the drives moving the mold to form a closed integrated unit with the reservoir and rotating this unit in the process of pouring the molten metal and slag into the mold.
