PURPOSE: To perform stable operation and establish production technology of products having low cost and high quality by adding non-magnetic CuO-Fe2O3 containing 0 to 10% of CuO and 80 to 100% of Fe2O3, thereby developing a non-magnetic mold flux having high quality and high efficiency. CONSTITUTION: The non-magnetic mold flux comprises 25 to 45 wt.% of CaO, 20 to 50 wt.% of SiO2, 0 to 20 wt.% of Al2O3, 0 to 5 wt.% of K2O, 0 to 5 wt.% of TiO2, 0 to 10 wt.% of MgO, 1 to 20 wt.% of Na2O, 0 to 20 wt.% of CuO-Fe2O3, 0 to 4 wt.% of Li2O, 0 to 10 wt.% of MnO, 1 to 10 wt.% of F and 1 to 30 wt.% of C.
