The heavy rail must be produced by high precision rolling method, so it is necessary to produce heavy rail by universal mill.
所以要保证高速铁路钢轨的精度，就必须有一种比较好的轧制工艺，万能轧制成为最好的选择。
For heavy rail rolling by universal mill, a simplified 3-dimention theoretical model is built firstly.
在重轨万能轧制过程中，首先建立了简化的三维理论模型。
Minitype rolling mill exploitation has gone to the lavatory for the experiment and scientific research have provided quite a few, the improvement the main body of a book has been carried out on present use rolling mill of precise copper of our university laboratory, has adopt gear wheel deflection falling-in way to have realized rolling mill controlling to rolling thickness, the rolling mill improving the day afer tomorrow has adopt three set of gear wheels to be engaged, two set of gear wheels axes among them may slide respectively along the erect sliding rail and the arc sliding rail, come true thereby to controlling rolling thickness.
小型轧机的开发为实验和科研提供了不少方便，本文对我校精密铜实验室现用轧机进行了改进，采用了齿轮变位啮合办法实现了轧机对轧制厚度的控制，改进后的轧机采用三组齿轮啮合，其中两组齿轮的轴线可分别沿竖直滑轨和弧形滑轨滑动，从而实现对轧制厚度的控制。
