PLASMA APPLICATION IN THE STEEL-INDUSTRY IN JAPAN

Recent advances are reviewed on several aspects of thermal plasma technology, particularly the works presented in the research group of thermal plasma processing in Iron and Steel Institute of Japan (ISIJ). Included is a brief description of the following fields. 1) Fundamental Studies of high power arc, application of magnetic field to the plasma arc, and thermionic electrode in the plasma torch . 2) Application of high power plasma arc to the heating, melting and refining in industrial and laboratory scales 3) Production of ultra fine particles of metals, ceramics and their composites by low pressure hydrogen arc. 4) Some fundamental studies relating with plasma synthesis, chemical vapor deposition, and others.
