为了探讨利用现有带钢连续退火线生产冷轧钛带产品,基于ABAQUS仿真平台,针对国内某带钢连续退火炉设备条件,建立钛带在退火炉内弹塑性变形的有限元仿真模型,并开展数值模拟研究。结果表明,炉辊辊形、钛带初始板形缺陷及钛带工艺张力大小是钛带张应力横向分布的主要影响因素;钛带的张应力横向分布不均度在凸度辊、单锥度辊和双锥度辊上依次趋于严重;钛带的初始板形缺陷使其张应力横向分布更不均匀,初始有边浪和中浪的钛带都会出现张应力分布不均匀现象;工艺张力对于钛带张应力横向分布均匀性影响不大。针对钛带张应力横向分布的影响因素及其影响规律的研究结果,对于设计炉辊辊形和确定对来料钛带实际板形的要求都具有参考价值。
In order to discuss the production of cold-rolled titanium strip using the existing strip continuous annealing line, a finite element simulation model of elastic-plastic deformation of titanium strip in an annealing furnace was established according to the ABAQUS simulation platform according to the equipment conditions of a continuous strip annealing furnace in China Carry out numerical simulation. The results show that the main factors influencing the transverse distribution of tensile stress are the hearth roll shape, the initial shape defects of titanium strip and the process tension of titanium strip. The transverse distribution of the tensile stress of titanium strip is uneven between the crown roll, And double taper roller tended to be serious. The initial plate-shaped defect of titanium strip made its transverse stress distribution more uneven. The initial tensile stress and the medium-waved titanium strip all showed uneven distribution of tensile stress. The horizontal distribution of tensile stress has little effect on the uniformity. According to the research results of the influence factors of the transverse stress distribution and the influence law of the titanium sheet tensile stress, it is of reference value for the design of the furnace roll shape and the determination of the actual shape of the incoming titanium strip.
