  • Controlling the geometry of workhardened strip in annealing lines using specially designed pilot equipment and developing an optimised control system for strip geometry


Cold reduced strip arriving at the annealing line can exhibit a range of shape defects, which can cause considerable processing problems as well as producing poor quality exit annealing. Poor strip shape progressing through the line can develop tracking problems and in extreme cases surface damage from coming into contact with the furnace walls. This project investigated the possibility of both measuring and correcting any poor shape in front of the furnace as well as within the furnace. The conclusion from theoretical studies and practical implementation is that strip shape can be both measured and corrected within an annealing furnace. Further work is required to fine tune the measurement and care necessary when developing any correction system as other problems like tracking or buckling may result.
