High-Temperature Simulation of Continuous Casting Mould Phenomena

The present investigation describes experimental simulation methods to evaluate the performance of mould powder during the continuous casting of peritectic steel. The dip mould simulator method developed in this investigation will take into account the actual mould powder along with the steel to be cast and certain casting parameters (casting speed, oscillation frequency and stroke) to evaluate the suitability of casting steel in the continuous caster. Another experimental technique akin to industrial practice has also been designed and proposed to study the melting behaviour of mould powder. Melting rate determined in this study for peritectic grade flux is in agreement with the theoretical melting rate estimated using a method proposed by K.C. Mills. The cast structure obtained from the dip mould simulator possesses oscillation marks and other features (slag infiltration) akin to the industry practice.
