Abstract
The refining additive is an alloy in the form of granules of a metal selected from the group of alkaline earth metals and zinc with a small quantity of a metallic element capable of giving the alloy a substantially lower melting point. The alloy can be a eutectic alloy. This alloy, which is in the form of granules, allows the treatment of steels, cast iron and non-ferrous metals at lower temperatures and with a substantial reduction in bubble formation. The alloy may be introduced in the form of a core wire.
