Autor: K. Tanaka, Masafumi Zeze, S. Fukunaga, Takehiko Toh, K. Tunenari, M. Tani, K. Hayashi, Kenji Umetsu

Publikováno v: International Journal of Cast Metals Research. 22:298-301

To improve the surface quality of cast slabs in the steelmaking process, the pulsating electromagnetic casting (EMC) technique was developed and assessed using a slab casting bench scale test. Numerical simulation of the magnetohydrodynamic field and

Theoretical Consideration of Heat Flux Distribution of Arc Driven by AC Magnetic Field

Autor: Takehiko Toh, Masaya Sugimoto, Koichi Takeda, Seiichi Sudo, Takeo Yamamoto, Naomi Matsumoto

Publikováno v: ISIJ International. 49:1845-1849

A magnetically driven arc is produced by imposing an external magnetic field to a transferred arc. Its width is determined by the amplitude of its oscillatory motion. Its heat flux distribution can be controlled by the waveform of the magnetic field.

Kinetics Evaluation of Inclusions Removal during Levitation Melting of Steel in Cold Crucible

Autor: Hideaki Yamamura, Hiroyuki Kondo, Shin Ichi Shimasaki, Masamitsu Wakoh, Takehiko Toh, Shoji Taniguchi

Publikováno v: ISIJ International. 47:1625-1632

Transport phenomena of inclusions during levitation melting of steel samples in a cold crucible are discussed by use of numerical simulation. Taking account of various forces acting on the inclusions during fusion, population balance simulation is pe

Inspection of the Defects of Steel by Using Laser Induced Breakdown Spectroscopy

Autor: Hideaki Yamamura, Michihiro Aimoto, Hiroyuki Kondo, Takehiko Toh

Publikováno v: Tetsu-to-Hagane. 93:483-488

Quick evaluation technique of the defects of steel materials by Laser-Induced Breakdown Spectroscopy (LIBS) was established. A Q-switched Nd-YAG laser with high pulse energy was used for laser breakdown, and the emission from breakdown plasma was tra
