【摘要】：为满足难变形材料轧制实验研究,开发新型实验轧机.采用液压张力缸和液压夹头夹持短试样,实现直拉张力轧制.采用两台主电机对上下工作辊单独传动和速度调整,实现异步轧制时速度比连续调整.将夹持轧件两端的夹头作为正负极,通低电压大电流,对轧件进行电阻加热,实现温轧功能.利用该新型实验轧机进行验证实验.对3%Si无取向硅钢进行带张力异步轧制,异步比设定为1.12,总压下量增大28.4%.对AZ31镁合金进行带张力温轧实验,厚度由4 mm轧制到0.633 mm,顺利完成轧制并得到很好的表面质量.实验表明,该实验轧机可以作为难变形材料轧制实验研究的有力工具.
[Abstract]:A new type of experimental mill was developed to satisfy the experimental research of hard-deformation material rolling. By using hydraulic tension cylinder and hydraulic chuck to clamp short sample, straight tension rolling is realized. The speed ratio of asynchronous rolling is adjusted continuously by using two main motors to drive the upper and lower work rolls separately and adjust the speed. The clamping chuck at both ends of the rolling piece is used as the positive and negative electrode, the low voltage and high current are passed, and the resistance is heated to realize the function of warm rolling. The new experimental mill is used to carry out the verification experiment. The 3%Si non-oriented silicon steel was rolled by asynchronous rolling with tension. The asynchronous ratio was set to 1.12 and the total reduction increased by 28.4kyr. The strip tension warm rolling test of AZ31 magnesium alloy was carried out. The thickness of the alloy was rolled from 4 mm to 0.633 mm, and the good surface quality was obtained. The experimental results show that the rolling mill can be used as a powerful tool for the experimental study of difficult deformation materials.
