Monitoring method for a continuous casting mould including building up a database

A method of monitoring for a continuous casting mold for casting a metal strand using monitoring equipment which performs the steps of:

• detecting quantities;
• automatically detecting metrologically at least some of the quantities during the casting of the metal strand;
• determining and temporarily storing operating parameters of the continuous casting mold by reference to the quantities detected;
• forming groups of operating parameters from the operating parameters, wherein each group of operating parameters in the groups of operating parameters includes at least one basic operating parameter and at least one respective supplementary operating parameter;
• automatically copying the operating parameters of each group of operating parameters into a database as a data record if the operating parameters of the group that are to be copied into the database are within a predetermined range over a relevant evaluation time period;
• assigning each of the at least one basic operating parameters of the groups of operating parameters as an input quantity, and a respective one of the at least one supplementary operating parameters of the groups of operating parameters as an output quantity for each of the at least one basic operating parameters;
• selecting at least one temporarily stored basic operating parameter;
• determining the data records held in the database with the input quantities that match the at least one selected temporarily stored basic operating parameter, and using the determined data records, determining permissible operating parameter ranges for the at least one supplementary operating parameters of the groups of operating parameters;
• and
• issuing to an operator of the continuous casting mold a warning message, and/or outputting a note as to which of the at least one supplementary operating parameters of the groups of operating parameters lies outside its respective permissible operating parameter range, and how the supplementary operating parameter that is outside its respective permissible operating parameter range can be brought back into its respective permissible operating parameter range, and/or immediately executing a corrective intervention by means of which a basic operating parameter of the continuous casting mold is altered, or communicating an applicable report to a control device for the continuous casting mold if the at least one supplementary operating parameters of the groups of operating parameters lie outside their permissible ranges.
