摘要
介绍了冷轧深冲搪瓷钢的成分特点及工艺要求,分析了钢板的组织结构、析出相及氢在钢中扩散系数和穿透时间。试制结果表明:以超低碳为基础,添加适量的合金元素,采用合适的工艺制度生产的冷轧深冲搪瓷钢DC03EK钢带既具有优良的深冲性能,又具有良好的抗鳞爆性能。
The composition characteristics and process requirements of cold-rolled deep-drawing enamelled steel were introduced. The microstructure, precipitated phase of steel sheet and the diffusion coefficient and penetration time of hydrogen in steel were analyzed. The results showed that： based on ultra low carbon, DC03EK cold-rolled deep-drawing enamelled steel which was manufactured by adding an appropriate amount of alloying elements and adopting the appropriate process system has excellent formability and good scaling resistance properties.
