Numeric Simulation of Three Dimensional Flow Field of Molten Steel in a Mould with High Efficiency Inner and Outer Couple Cooling

A new technology of high efficiency concasting based on inner-outer couple cooling of molten steel in a mould has been advanced, that is to set an inner cooling apparatus, U shape pipes, in a mould. The flow status of molten steel in mould with inner cooling apparatus is analyzed by using fluid dynamics analysis software FLUENT, and compared with that without inner cooling apparatus. It is found that the inner U-shape cooling apparatus can make molten steel flow with a lower impact depth which is favourable to inclusion in steel floating up.
