基于钢种凝固特性,分析了304不锈钢连铸坯振痕深的原因,并结合钢种本身特性确定了结晶器振动的最佳工艺参数取值;通过研究反向振动同步控制模型的特点,提出了该模型的具体构造方法,为最佳同步控制模型的建立奠定了基础,进而得出适合304不锈钢的正弦反向振动同步控制模型,可减小振痕深度,保证良好的铸坯表面质量。本研究不仅适用于304奥氏体不锈钢本身,而且对其它钢种的同步控制模型的建立同样具有借鉴意义。
Based on the solidification characteristics of steel, the reason of deep oscillation of 304 stainless steel billet was analyzed. Based on the characteristics of steel itself, the optimum process parameters of mold oscillation were determined. By studying the characteristics of the synchronous vibration control model, The concrete construction method of the model lays the foundation for the establishment of the optimal synchronous control model, and then obtains the synchronous control model of sinusoidal reverse vibration suitable for 304 stainless steel, which can reduce the vibration mark depth and ensure a good slab surface quality. This study not only applies to 304 austenitic stainless steel itself, but also has reference significance for the establishment of synchronous control model of other steel types.
