Design Principles of Mold Powder for High Speed Continuous Casting

Abstract

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.
