Apparatus and method for charging metal chips into a molten bath of the metal from which the chips are formed, comprising a compacting extruder and a delivery conduit which is resistant to the mass of molten metal and which is pivotable to dip into the molten metal bath when chips are being charged thereinto and out of contact with the bath when charging is to be discontinued, are disclosed. The chips are forced through the delivery conduit in the form of a compacted or densified mass preferably having a density between about 30 and 60 percent of the density of the solid metal and preferably between about 55 and 80 pounds per cubic foot. Feed is continued while the delivery conduit is in the molten metal bath and until it is removed therefrom to prevent entry of molten metal into the delivery conduit. The method is preferably conducted on a continuous basis and various sensors with appropriate wiring may be employed for safety and for making the method substantially automatic in operation.
A method for the industrial utilization of metal chips which involves the introduction of said metal chips into a mass of molten metal of which said chips are formed, comprising the steps of:
An apparatus for the introduction of metal chips into a mass of molten metal of which said chips are formed, the combination comprising:
