Abstract
In this addn., the feeding of an addn. or alloy in the form of a wire travelling at a prescribed initial speed into molten metal flowing via a downgate into a mould is described. The novelty is that the momentary casting speed of the molten metal is continuously determined, and the feeding rate of the wire is automatically adjusted in accordance with the alteration in casting speed. In the pref. casting process, the mould is located on an electronic weigher fitted with load cells connected to an amplier feeding a computer; and the computer feeds signals to a controller adjusting a variable speed motor driving rollers which feed the wire into the molten metal. Process ensures that the addn. or alloying element(s) are uniformly distributed in the molten metal and in the casting.
