Abstract:
No matter what flatness of strip is whether flat or defective at
anneal furnace entrance，strip can not keep it’s original shape and a
remarkable large deflection has took place at anneal furnace exit. By
tracking this phenomenon at 2030 continuous anneal line, the mechanics
model of strip thermodynamics behavior in continuous anneal furnace is
builded. The mechanism of flatness changes and the variations of these
changes with the contributing factors are researched by the famous
finite element software——ANSYS. Conclusions are achieved from the study,
which may be used to improve technologies and decrease strip
heat-buckling of 2030 continuous anneal processing line and hot
galvanization line.
Key words: Cold rolled strip Anneal furnace Large deflection Finite
