为了解决正常生产结构条件下,无取向硅钢热连轧工作辊磨削辊形受热辊形影响难以获得工艺制度期望的初始辊形问题,结合无取向硅钢热轧生产过程,采用二维有限差分法建立了工作辊轧制过程中的工作辊温度场计算数学模型,使用有限元软件ANSYS建立了工作辊下机后空冷和喷淋冷却混和工艺条件下温度场模型,开展了无取向硅钢热轧工作辊一个完整使用周期内的温度场和热辊形仿真研究,提出了无取向硅钢工作辊热磨辊数学模型和热磨辊工艺制度,并投入生产应用.相同生产工艺条件下,1700热连轧机无取向硅钢轧制应用热磨模型和热磨工艺制度后,产品的凸度和楔形双达标率由67.39%提高到74.57%的明显生产实绩.
In order to solve the problem of initial roll shape, which is affected by the roll shape of the work roll of the non-oriented silicon steel continuous rolling mill, it is difficult to obtain the initial roll shape problem expected by the process system. In combination with the hot-rolling production process of the non-oriented silicon steel, two-dimensional finite difference method The mathematical model of the temperature field of the work roll in the process of work roll rolling was established. The temperature field model of the work roll after under-machine air-cooling and spray cooling and mixing process was established by the finite element software ANSYS. Roller temperature cycle and hot roll shape simulation study of a full use cycle, put forward a non-oriented silicon steel work roll hot grinding roll mathematical model and hot grinding roll process system, and put into production and application of the same production process conditions, 1700 hot strip mill Non-oriented silicon steel rolling application hot mill model and hot grinding process system, the product crown and wedge double standard rate from 67.39% to 74.57% significant production performance.
