Measurement of Velocity Field in Meniscus Zone in Mold of Continuous Caster

Velocity field in meniscus zone in mold is studied on the c. c. simulator. Low melting point Pb-Sn-Bi alloy and silicon oil are adopted as simulators of molten steel and slag,respectively. It is shown that the liquid metal in meniscus zone flows toward the mold wall during the positive-strip period and flows away from the mold wall during the negative-strip period. It is also found that the flow velocity at meniscus increases during the positive-strip period and decreases during the negative-strip period at higher casting speed.
