Numerical Simulation of the Temperature Distribution in a Continuous Casting Process for the Production of AlSn(Cu) Alloys

摘要

The results of numerical simulations of the temperature distribution in a continuous casting process are presented. In a so-called "belt-caster", a strip of AlSn(Cu) alloy is continuously pulled out of a basin with the melt. The strip is led between two glass-fibre belts which are in close contact with water-cooled copper plates. The simulation project consisted of several steps: (a) determination of the thermophysical properties of the alloys used in the liquid, in the solidification range, and in the solid range; (b) measurements of the spatial temperature distribution in the strip as a function of the strip velocity by thermocouples; (c) inverse simulation with the results of (a) and (b) in order to determine the heat transfer coefficients between the strip and the surroundings including the glass-fibre be (d) direct simulation of the temperature distribution in the continuous casting device with the possible variation of casting parameters.
