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