摘要：两辊轧机一般是指轧辊水平布置的轧机，两个轧辊上下布置在同一垂直平面内，其结构简单、用途广泛。异步轧制是一个新的轧制工艺，有许多优点，尤其在一些复合材料上，因为一些复合材料上下表面的延伸率不一致，为了保证产品板型质量必须采用异步轧制。采用异步轧制可以大大地降低轧制力，所以设备重量轻，能耗低，轧机变形小，产品精度高；减少了轧辊的磨损和中间退火，降低了生产费用；轧制道次少，生产率高；轧机可轧厚度大。本研究的课题是两辊异步轧机的主机设计，完成轧钢机的主机设计和相应的测控传感器的安装，并对轧钢机部分功能以及结构方面进行改进和创新，使其能够高效、平稳、精确地生产合格的产品。6200

Two roller asynchronous mill mainframe design
Abstract：Two roller mill usually refers to the level of rolling mill roll decorate, two roll up and down in the same vertical plane within decorate, its simple structure, used widely. Asynchronous rolling is a new rolling technology, has a lot of advantages, especially in some composite materials, because some of the top and bottom surfaces of the composite elongation rate not consistent, in order to guarantee the product quality of plate type must be of the asynchronous rolling. The asynchronous can greatly reduce rolling rolling force, so equipment light weight, low energy consumption, little deformation rolling mill, the products high precision; Reduce the wear and tear on the roll of finally, reducing production cost; Rolling road less time, productivity high; Rolling mill can be rolling in thickness. This topic was two roller mill asynchronous mainframe design, complete the mainframe design and corresponding rolling mill and control the sensor of the installation, and the function and structure of rolling mill in improvement and innovation, make its highly efficient, stable and accurate to produce quality products.
