Analysing and Computing of Adjustable Parameters of Horizontal Wheel Rolling Mill with Seven Rolls

The train wheel rolling mill of Steel Wheel Factory of Tai Yuan Heavy Mechanical (Group) Limited Company are introduced. The speed relationships among oblique rolls, wheel and main roll and cross section circle line equation of middle cone section of oblique rolls are determined. The contact area among each part of oblique rolls, pressure rolls and wheel and horizontal, vertical component of force of each section of oblique rolls are computed. In addition, through analyses of forces under the condition of being dynamic Steady in the Process of wheel rolling, each mutual function forces are got.
