Abstract

A three-dimensional model of the thick slab continuous casting mould of 400 × 2200 mm was established. The effects of immersion depth of nozzle and casting speed on the flow field and temperature field were investigated. The high temperature distribution in mould, the thickness of narrow face solidified shell, the impact position of stream and the free surface velocity were used as the main points of analysis. Simulation and practical water modelling both exhibited the same changing trends, namely, the flow velocity of the surface increases with the distance from nozzle. The scientific basis for optimizing the flow field and temperature field in the continuous casting of special thick slab mould was acquired through calculations.
