Abstract
An arrangement for the delivery of predetermined amounts from a sealed and heated storage vessel. The storage vessel has an overflow pipe and a closeable opening for insertion of a molten charge. An intermediate vessel, which is sealed, communicates with the overflow pipe of the storage vessel. The intermediate vessel has a delivery pipe for delivering measured quantities of the molten metal. The intermediate vessel also includes means for measuring the molten charge within the vessel. The flow of the molten metal is controlled by pressurized gas lines which are selectively turned on and off. The arrangement includes a throttle control and storage element for controlling the quantity of molten charge delivered as a function of time. Means for supplying an inoculant or seeding agent are disclosed.
