Numerical modeling of heat transport in the continuous casting mould as a coupled problem

Popis výsledku v původním jazyce

The paper deals with modelling of heat transport in the mould of continuous casting and determination of thermal boundary condition. A layout of heat flux on the working surface of the mould walls is required. A special experimental mould instrumented with thermocouples in the copper walls was used for determination of the heat flux layout. Instead of the demanding mould instrumentation, a numerical simulation technique for the heat flux layout determination was proved. The method uses the feature of gas gap thickness calculation and an automatic thermal boundary modification of the software ProCAST. The task is solved as a coupled thermal-stress problem. It follows from simulations that the ratio of heat flux near mould corners to heat flux in the middle of the wall drops down to 20%. The minimum of the ratio was found at the bottom of the mould for low casting speeds. The obtained heat flux layout can be used as a boundary condition for operational thermal numerical models.
