Abstract This research aimed at conducting a quantitative investigation of process parameters on the magnetic field contribution in an electromagnetic continuous casting mould. The Taguchi method (4 factors and 3 factor value levels: L9 orthogonal array) was adopted to design matrix of the simulation runs and the analysis of variance was used to evaluate the contributions of each control factor. The simulations were conducted based on the finite element method and the numerical set-up was validated by the designed experiment. The results showed that the applied alternating current magnitude contributed most (76.64%) to the magnetic field level in the mould, compared to the other control factors. It was followed by the slit length (17.72%), the alternating current frequency (4.17%) and the slit width (1.57%). Highlights Numerical system was validated by the designed experiment. A quantitative investigation of process parameter on the magnetic field in contribution an EMCC mould was conducted. The current value was the most influential factor, followed by the slit length, current frequency and the slit width.

A model on non-sinusoidal oscillation of continuous casting mould was established to study the pressure in flux channel. The effects of oscillation parameters on the pressure in flux channel were researched. The non-sinusoidal oscillation parameters were optimized. When the casting speed is 1.8 m·min-1, the optimized oscillation parameters are: non-sinusoidal factor (α) is 0.198, oscillation amplitude (s) is ±4mm and oscillation frequency (f) is 165min-1. When the casting speed is 2.0 m·min-1, the optimized oscillation parameters are: α is 0.186, s is ±4.5mm and f is 155min-1. These optimized oscillation parameters are proved applicable in practice.

Heat Transfer By Radiation

AbstractThe paper presents the results of research concerning the influence of radiative heat transfer on the strand and mould interface. The four models for determining the heat transfer boundary conditions within the primary cooling zone for the continuous casting process of steel have been presented. A cast slab - with dimensions of 1280×220 mm - has been analysed. Models describing the heat transfer by radiation have been specified and applied in the numerical calculations. The problem has been solved by applying the finite element method and the self-developed software. The simulation results, along with their analysis, have been presented. The developed models have been verified based on the data obtained from the measurements at the industrial facility.
