Title: Sealing gap between ingot moulds and bases - using simple vibrating device for packing waste matl. in gap to prevent run-outs
Inventor: BREITZMANN KONRAD
IPC: B22D7/06
Filed: 1973-04-18
Abstract: The device consists of a shaft, tha bottom end of which terminates in a cone that extends almost to the mould wall leaving a narrow gap. A funnel is mounted on the top end of the shaft and is filled with feather-shot or granules of a material with a higher specific gravity than molten steel (e.g. waste prods. or a directly-reduced material).
