Abstract
In order to develop a mold oscillation-less continuous casting process, i.e . to replace the mold oscillation by an intermittent alternating magnetic f ield in a continuous easter, a model experimental work has been conducted u sing molten tin and gallium with low melting point, densities of which are as large as molten steel. The behavior of the mold flux penetrating into a flux channel between the molten metal and the mold and the process forming oscillation marks due to the mold oscillation were visualized, It was found that mold flux can penetrate periodically under the imposition of the inte rmittent alternating magnetic field even if without mold oscillation. The m easured penetration depth of the mold flux agrees well with model predictio ns. Finally. the molten tin was continuously cast in a cold crucible type c opper mold under the imposition of an intermittent alternating magnetic fie ld instead of mold oscillation. It is noticed that molten tin can be succes sfully cast with the imposition of the magnetic field but can not without i t.
