RESUMO

The development and application of simulation software for the continuous casting process is proposed in this work. The heat transfer and solidification models were validated with experimental results of temperature measurements in an industrial plant as well as with steel billets samples. Thermocouples embedded in the mold walls were used to measure temperatures along the mold length and non-contact pyrometers positioned at different locations along the machine were used to monitored the strand surface temperatures. The model seemed to predict quite accurately the continuous casting simulation when calculated results were compared with experimental measurements. In this study, steel billet with square section of 240 mm, 180 mm and 150 mm were analyzed. Some of the monitored heats were used to adjust thermal parameters as the heat transfer coefficients. After, the model results were compared with results from a heat transfer model of literature. With the simulation software properly calibrated, numerical and experimental correlations were performed to analyze the influence of thermal parameters (¿, c, k, TL, TS), process parameters (TV, VL, CQ) and structural parameters (¿1, ¿2, TCE) in the evolution of solidified shell and thermal profile of the billets. Therefore, empirical equations that correlate these parameters were analyzed and subsequently adopted in the numerical model.
