Addition of Alloying Elements to Copper Melt by Cored Wire Feeding
Cored wire feeding was applied to the alloy composition adjustment of copper melt, which has been used mAlnly in steel making industries as well as in ductile iron making industries. This paper reports on the change in chemical composition after adding Fe, Zr and Mg into the copper melt respectively by two alloying methods, that is, powder addition and alloy wire feeding in a lab scale furnace. The recovery varied with the location in the ingot due to the non-uniform distribution of elements in the melt irrespective of what type of element was added. The highest recovery was obtAlned in Fe by both addition methods. While Mg recovery was almost zero by powder addition method, the recovery increased to 27.5％ by cored wire feeding. Cored wire feeding was significantly more effective than direct powder addition into the copper melt. It was also identified from the calculation that the importance of the depth where the fed wire is melted completely in the bath and wire feeding velocity to enhance the recovery of the alloying element.
