When impurities such as metals such as iron, silicon, manganese, etc. are in the form of oxides, or active parts 1 are floating stones of peroxidized steel such as Cu2O3. According to the present invention, since the sulfite used to treat cupric oxide is a deoxidizing and reducing agent, it is possible to suppress the change of impurities into oxides, and to reduce the activity of active parts.
