摘要
从纵向厚度和横向厚度两个角度介绍了非晶薄带厚度控制研究情况。纵向厚度方面,喷嘴间隙、冷却辊转速、辊嘴间距等工艺参数是主要影响因素,对各种厚度控制的经验公式进行了比较;实际生产中,纵向厚度控制主要是对辊嘴间距的控制。相对于纵向厚度控制,横向厚度控制更为复杂,主要分析了喷嘴横向形状、熔潭稳定性、冷却辊辊型三个主要因素对横向厚度的影响。非晶薄带厚度控制还必须结合相关制带工艺的研究,与带材厚度检测相结合,实现非晶带材厚度的自动闭环控制,才能进一步提高厚度控制水平。
Progress in research on thickness control of amorphous ribbons is reviewed from the view of the thickness of longitudinal direction and cross-sectional direction. For the control of longitudinal thickness, the main process parameters are the gap of nozzle, the wheel velocity, the distance between nozzle and the wheel. And the difference between emporical equation are compared. In the industry, the major method for the control of longitudinal thickness is to control the distance between nozzle and the wheel. Compared with longitudinal thickness, the control of cross-sectional thickness is more complicated. The influence of nozzle shape, the stability of puddle, wheel shape is discussed. Furthermore, it is important for the combination of the research of process parameters and the detection of thickness to achieve the closed-loop control and high level thickness control.
