Abstract: Not only elastic deformation of the roller is considered,
but also elastic deformation of the rolled piece is considered, a set of
new rolling pressure model about the thin strip level is established. In
this model, for general thin strip the asymmetry of the stagnant zone is
considered, the friction distribution in the deformation stagnant zone
is analyzed by the combined frictional theory; for the super thin strip,
according to the character that during leveling the plastic zone is
reduced relative to the elastic zone and in the friction model the
stagnant zone is not limited in the plastic zone and maybe extends into
elastic deformation zone, the distribution of relevant unit rolling
pressure is deduced in detail. At the same time, to validate the
accuracy of relative model, the theoretical calculation of the rolling
pressure of Bao Steel 1550CAL leveler relative typical specification
products is made by this model and the relevant rolling pressure is
practically measured on-line. The calculated results coincide better
with practical measured results and completely achieve the prediction
accuracy requirements required by the engineering. Therefore, this model
haves important theoretical meanings and use values and can be further
popularized and applied.
