This paper introduces the detection principle of the shape meter for cold rolling strip.

Targeted at optimum plate shape,penalty function is employed to fully optimize the pressing,tension and speed pattern of a 350mm cold tandem mill and on this basis,the roll shape is determined.

Presently direction for improve the quality of cold rolling is: increase the roller use technology; optimize roll profile; increase the quality of detect grinding and crack; analysis and avoid the various factor of disability of roller.

Therefore further analysis on the pattern of LEVI'S jeans show that the sloping characteristic of cloth's weft yarn causes the unsymmetry of inside seams of trouser legs, and its excellent sport function has close relation with the treating technique of LEVI'S corporation.

This article mainly explains "the fish dart" design of the men s clothing pattern by the concise language.

Optimum design of the deck shape in composite slim floors with deep deck;

The experimental data indicate that the non-symmetric cross rolling process not only produces reliable control on both shape of strip and lateral thickness deviation, but also reduces significantly the power thickness deviation, but also reduces significantly the power consumption and rolling pressure, and the latter could extend the service life of rolls.
