In the feeding of molten metal from a container therefor, e.g., a storage basin, a furnace or a crucible, to a chamber, e.g., an injection cylinder or a dispensing chamber, having an electromagnetic pump partially immersed in the container, the outlet of the pump being connected by a feedline to the chamber, the molten metal is metered by apparatus comprising a detachable ascending control pipeline connected to the feed pipeline, an electromagnetic presence detector arranged to detect molten metal in the control pipeline at the level of the filling height of the chamber, and a progressive voltage generator connected in series with the electrical circuit of the pump and including a starter circuit and a stop circuit to which the presence detector is connected.

Metering apparatus for molten metal

Industrial treating of corrosive molten metals by a gas within molten liquid duct of a treating electromagnetic pump comprising an installation in which the input of said treating pump is connected to an ascending pump immersed in said molten metal and the output of said treating pump is connected to a degassing tank provided with a spout pouring out the treated molten metal.
