RFID Tag Monitoring for Continuous Casting Crystallizer Parameter Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring and maintaining casting elements, such as crystallizers, in steel production plants are inefficient, leading to incorrect setting of functional parameters, increased maintenance times, and reduced productivity due to lack of accurate wear analysis and data retention.
Innovation Solution
Implementing a readable/writable RFID tag to store and retrieve identifying and operational parameters of each casting element, allowing for automatic setting of process parameters and maintaining a record of usage data, including hours of operation and casting speed, to facilitate efficient reinstallation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual setting of identification parameters is performed during crystallizer installation, then the functional parameters can be configured, but errors may occur and installation time increases
Solution Approach 1:
The patent uses RFID tags to store and transfer identification parameters digitally, replacing manual configuration with automated data copying from the tag to the control system. This eliminates human error in parameter entry and reduces installation time significantly.
Solution Approach 2:
The patent replaces the manual mechanical process of parameter setting with an electronic/automated system using RFID reading and writing capabilities. The control system automatically reads parameters from the RFID tag and configures the crystallizer without manual intervention.
2Measurement precision
If crystallizers are removed for maintenance and inspection, then wear and tear can be evaluated, but operational continuity is disrupted and maintenance time increases
Solution Approach 1:
The patent implements continuous monitoring of crystallizer parameters during operation, providing real-time feedback on operational conditions and wear indicators. This allows for predictive maintenance scheduling based on actual usage data rather than fixed intervals, reducing unnecessary removals.
Solution Approach 2:
The patent stores historical operational data and wear indicators in the RFID tag before removal is needed. This preliminary data collection allows for accurate wear assessment without requiring extended inspection time, enabling faster maintenance decisions.
3Reliability
If maximum operating hours are enforced for crystallizers, then safety is maintained, but productivity is reduced due to frequent replacements
Solution Approach 1:
The patent transitions from a static, fixed-hour replacement schedule to a dynamic maintenance strategy based on actual crystallizer condition monitoring. The system continuously tracks operational parameters and wear indicators, allowing extensions beyond standard hour limits when conditions permit, thereby optimizing both safety and productivity.
4Loss of information
If complete operational data is stored for each crystallizer, then accurate wear analysis is possible, but data management complexity increases
Solution Approach 1:
The patent uses a universal RFID tag system that serves multiple functions: storing identification parameters, tracking operational hours, recording wear indicators, and maintaining historical data. This single multi-functional storage solution simplifies data management compared to multiple separate systems.

AI summary
Method to monitor a casting element, for example a crystallizer (10) or an ingot mold (20), which can be used in continuous casting in a production plant for steel products, comprising at least an installation step in which each casting element (10, 20) is associated with a corresponding casting unit. The method comprises an operating step in which the casting element (10, 20) is used to produce the steel products by casting molten metal in the crystallizer (10), wherein the production of the steel products is controlled and supervised by electronic processing and control means (40). Memorization means (30), operatively connectable to the processing and control electronic means (40), are univocally and stably associated with each specific casting element (10, 20) before or during the installation step, and in which specific, identifying parameters are memorized before the casting element (10, 20) is used. The identifying parameters read by the electronic processing and control means (40) are used at least to automatically set predetermined functional process parameters at the beginning and/or during the operating step.
