Debugging of the strip shape control system for a foil mill.
In May, 2026 the JSC ASC specialists together with LLC ASC-Cifra specialists and also with assistance of AO RUSAL SAYANAL production engineers finalized the automatic strip shape control algorithms for foil mill C3-2. The modes for calculating the actual flatness curve skewness and inflection coefficients were added to the roll body cooling circuit. These modes allow using the strip edges only for evaluation. The width of the edges can be set by a roller man by means of changing the quantity of zones.
This modification was implemented based on experience of operating the mill over the past year, since the time when a new mill control system was placed into service by ASC company.
The improved algorithm will speed up the response of automatic flatness control system and eliminate strip burnouts along the edges while working in automatic mode.
