Lirias is developed by LISMAR and is an abbreviation for LISMAR Roll Information and Analysing Software. LIRIAS is developed to assist roll shop managers to have quick access to the roll inspection results of the LISMAR systems. LIRIAS makes it possible to analyse all types of LISMAR roll inspection results (ET, UT and SW). The results can be displayed simultaneously on the monitor in different charts (Z-plots, C-scans and D-scans). When the LIRIAS program is connected to all grinding machines through a network, LIRIAS will file and order all the inspection measurements of the LISMAR systems under the roll-number of the inspected roll. This can be viewed on-line and does not depend on which grinding machine the roll is ground on, thus resulting in easy access to the history of each roll's measurements.
