An Effective Inverse Heat Transfer Procedure Based on Evolutionary Algorithms to Determine Cooling Conditions of a Steel Continuous Casting Machine

AbstractThe cooling conditions of a slab during continuous casting of steel have an impact on the crystalline structure formation. Numerical methods allow real processes to be modelled. Professional computer programs are available on the market, so the results of their simulations allow us to understand the processes that occur during the casting and solidification of the slab. The study attempts to evaluate the impact of the intensity of the secondary cooling on the chilled zone size. The calculations show the differences in the structure of a slab cast with various speeds while maintaining industrial cooling parameters during operation of a continuous casting machine.

Heat Transfer Coefficients

For the correct simulation of solidification and temperature evolution in the continuous casting of steel, the determination of boundary conditions describing the heat-transfer phenomena through the strand surface, in each cooling zone of the casting machine, is extremely important. These boundary conditions are usually expressed as heat fluxes or heat transfer coefficients. In the present study, the surface temperature of the steel billet was experimentally determined in a steelmaking plant by infrared pyrometers positioned along the secondary cooling zone during real operation of a continuous casting machine. These data were used as input information into an Inverse Heat Transfer Code, implemented in this work, in order to permit the heat transfer coefficients of each spray cooling zone to be determined. The resulting simulations of temperature evolution during continuous casting have shown that the solidification was not complete at the unbending point and that there was a risk of breakout at the mold exit under the adopted operating conditions.
