An addition material in powder or particulate form comprising at least one addition agent selected from the group consisting of calcium, magnesium and aluminum is extruded to provide a compact core wire, which is enveloped by a tape of iron or steel. The tape is circularly shaped such that one widthwise marginal portion is folded tightly over the other widthwise marginal portion in overlapping relation. The tape thus shaped serves as a protective covering for the core wire. Great lengths of continuous wire can be manufactured by the continuous production process. The wire shaped composite addition material produced in this way is added to molten iron and steel by means of continuous wire feeding and hereby provides for effective deoxidation and desulfurization of such melts. Furthermore the linear additive is easy to handle and to store.

Method of production of a wire-shaped composite addition material

A flame spraying material consisting of a wire obtained by compacting zinc powder, zinc-aluminum alloy powder or admixed powders of zinc and aluminum or consisting of a composite wire obtained by enclosing said compacted powders in an aluminum covering.
