    摘要: The present invention relates to a cover member for a graphite spheroidizing agent used to manufacture ductile cast iron. The cover member handles easily in high temperature and harsh work environments because it is lightweight, and has an effect as an inhibitor. The cover member is formed of the porous particles of volcanic silicate minerals containing 70-75 wt.% of SiO_2, 12-14 wt.% of Al_2O_3, 3-5 wt.% of K_2O, 3-4 wt.% of Na_2O, 0.7-1.5 wt.% of CaO, 1.2-1.5 wt.% of Fe_2O_3, 0.1-0.2 wt.% of MgO, and 0.05-0.1 wt.% of TiO_2.
