Exploitation and Application of the Middle Thickness Model in Cold Tandem Mill

Abstract

In the foundation of generous field test and theoretical research, we presented a calculated model of middle thickness in cold tandem mill by combining applied mathematical theory and production technology and taking advantage of Taylor series expansion, matrix analysis, Newton iteration method and other mathematical methods. This model was used for setting original middle thickness on 1220 cold tandem mill in some plant. After field usage, the result was fine and correlative precision was over 90%. It completely satisfies required precision in project and has the value to be further popularized and applied.
