Abstract:

After briefly discussing several rolling theories, the report gives a derivation of strip-thickness, roll force, and torque equations. These nonlinear equations are then simplified. All the basic functions are expanded in the three term-power series with respect to the mill variables. A computer program is developed which evaluates the coefficients of the series. The program consists of two main subroutines and allows all the mill coefficients to be obtained in less than 20 seconds on a CDC-1604 computer. The above scheme remains general for any type of metal being rolled. The method of obtaining coefficients which utilizes implicit differentiations made this program considerably faster, simpler and more accurate than any published computational schemes. A numerical example is included. Author
