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。
Introduction In the three-meter-three-four-roll reversing mill, two titanium sheets are used to produce wide-width pure titanium sheets. Through trial-production of the sheet metal rolling, the parameters of the group blank, heating and rolling are explored. The reasonable design of roll shape and roll shape curve can effectively control the same plate thickness of rolled pure titanium plate and obtain good shape. The wide pure titanium sheet with the size of 3.0 mm × 2000 mm × 6000 mm was developed. The results of the heat treatment showed that its mechanical properties fully met the standard requirements, and the surface quality, dimensions, Technical indicators are to meet the technical requirements of the relevant standards.
