Abstract

In order to develop of mold powder for high speed slab type continuous casting, viscosity of molten flux and melting rate are investigated. The results can be summarized as follows;
1) Viscosity of molten flux is estimated from the equation as a function of anion cation interaction parameter and net work parameter.
2) Melting rate is estimated from the equation as a function of carbon content per unit volume and carbonate content.
3) The improved mold powder succeeded in casting at 5m/min speed.
