摘要
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。
Causes of deep oscillation marks on the 304 stainless steel slab were analyzed based on solidi- fication characteristics of the steel. Combined with characteristics of steel structure, the optimum parame- ters for mold oscillation process were determined. By investigating characteristics of inverse oscillation synchronous control model, a specific model building method for the mold was proposed. It has been con- eluded that the sine-wave inverse oscillation synchronous control model designed for the 304 stainless steel can reduce the depth of oscillation marks and ensure good slab surface quality. The research results can not only be applied to the production of 304 austenitic stainless steel, but also serve as guidance to the establishment of synchronous control model for other kinds of steels.
