Abstract: Against
the phenomenon that the kiss between roller ends easily occurs in the
skin rolling of thin-narrow strip, the squeegee oil being used as
experimental material, a set of simple, practical kiss measuring method
which reflecting true rolling condition and has changed past
conventional method that the kiss research is finished through kissing
reagent paper in electrostatic experiment is explored. It not only may
audio-visually prove the kiss betweeen roller ends exists but may
measure the value of the kiss width quantitatively. On the base of it,
and associating product practice, a set of mathematical model about kiss
quantity, width of the kiss, rolling pressure and shape in the skin
rolling of super thin strip is established. At the same time, it gives a
calculation block graph , and calculates width of the kiss , rolling
pressure and shape in the different rolling condition through taking
classical product as example, and gives homologus experimental data. By
field experiments the accuracy of this model is validated. At present,
this model is applied to the practical set of field bending-roller force
and rolling pressure, and has achieved good using effect and vast
economic benefit.
Key words: Kiss
Rolling pressure Shape Bending-roller force
