With a 230 mm x2 150 mm slab caster at steelmaking works as an object of study
the effect of cast speed (0. 8 ~2. 3 m/min)
immersion depth of submerged nozzle (100 -200 mm) and slab width (1 100 ~2 150 mm) on heat transfer and solidification of liquid at action of flow field in mold has been analyzed by 3 dimensional numerical simulation. Results show that the change of casting speed and other parameters has no influence on basic characteristics of liquid flowing in mold
but can effect the development of slab shell at narrow side in mold. The change of immersion depth of submerged nozzle
slab width and casting speed effects overheat extent of liquid on surface of bath in mold in varying degrees
i. e. with smaller cross section
larger casting speed and smaller immersion depth of submerged nozzle
the overheat extent of liquid on surface of bath is larger
