In the figure, numeral 3 represents a wire delivery device for continuously delivering the magnesium wire 1.

た。By the way, sulfur has a strong affinity with Mg and consumes Mg and inhibits graphite spheroidization. Therefore, in the conventional magnesium wire method, a low S molten metal is required as the base metal, and for this reason, the pre-process As a result, a desulfurization process was necessary.

However, the wire used is a magnesium wire to which 5 to 20% of CaC2 as a desulfurizing agent is added. If the amount of CaC2 added exceeds 20%, the purity of Mg decreases and affects graphite spheroidization, which is undesirable. On the other hand, if it is less than 5%, the desulfurization effect becomes insufficient, which is not preferred.

増大する。Effects and Effects of the Invention When the magnesium wire for graphite spheroidizing treatment of the present invention is used, desulfurization proceeds by CaC2 in the wire at the same time as the graphite spheroidizing treatment by the wire method. Therefore, when producing spheroidal graphite cast iron or CV graphite cast iron, the desulfurization step required in conventional wire processing methods can be omitted, reducing costs and increasing production efficiency.
