Patent number: 5106411Abstract: A method of removing non-metallic inclusions from a molten metal by allowing the molten metal to pass through at least first and second vessels which are intermediate between a ladle and a mold. The molten metal is made to stay in the vessel for a period not shorter than 40 seconds while a horizontal rotation is imparted to the molten metal in the first vessel. The molten metal is then transferred from the first vessel to the second vessel. The molten metal in the second vessel is then heated. This method is suitably carried out by an apparatus comprising a first vessel having a discharge opening at its bottom and surrounded by a rotational magnetic field generating device for centrifugation of the molten metal in the first vessel, and a second vessel for receiving the molten metal discharged from the first vessel and provided with a heating device for heating the molten metal received therein.Type: GrantFiled: April 30, 1990Date of Patent: April 21, 1992Assignee: Kawasaki Steel CorporationInventors: Yuji Miki, Hidenari Kitaoka, Tetsuya Fujii, Shuji Takeuchi, Kenichi Sorimachi, Toshikazu Sakuraya, Fumio Sudo
