摘    要:介绍在三米三四辊可逆式轧机上采用两张钛板组坯叠轧生产宽幅纯钛薄板,通过对板材叠轧试制,探索相应的组坯、加热、轧制工艺参数。经合理设计辊形及辊形曲线,有效控制叠轧宽幅纯钛薄板材的同板差,并获得良好的板形。研制出尺寸为3.0 mm×2 000 mm×≥6 000 mm的宽幅纯钛薄板,热处理后的结果显示,其力学性能完全符合标准要求,且板材表面质量、外形尺寸、同板差等各项技术指标均满足有关标准的技术要求。

Abstract: The wide titanium sheets were produced using two titanium sheets as a rolled group with the 3.3 m four-high reversing mill. The parameters of corresponding group billet, heating, rolling process were explored through the trial. The difference with the wide titanium sheet can be controlled effectively and a good shape can be obtained when the rational rod-shape and its curve were designed reasonably. Wide titanium sheet with a size of 3.0 mm×2 000 mm×≥6 000 mm was developed. It shows that the mechanical properties meet the requirements of the standards, and the surface quality, dimensions as well as the difference with the wide titanium sheet are all meet the technical requirements of the relative standard after heat treatment.
