Purpose: of this paper: This paper described the analysis of the issue of monitoring and diagnostics of surface of narrow crystallizer’s desks. There is described the development and the achieved laboratory results based on laser object surface scanning. The diagnostic system which is currently creating will be part of management systems to support service life of crystallizer as a part of continuous steel casting device. The emergence of weariness is caused by many factors, influences and processes that act and run directly on the device, its individual parts, through its operation. These effects result in changes in the device surface’s properties and its components and are the primary cause of technical failures that affect both, the efficiency of the process, and also the life of the individual parts. Design/methodology/approach: The focus of the used solution is increasing of advantages of the continuous steel casting device, which can be achieved only by management system’s that will minimize undesirable influences on the technological process. Among the significant side effects affecting the efficiency of the process of the continuous steel casting device belong wear of the crystallizer which is causing disturbance and operation disruption. Findings: There was created a methodology for evaluation of crystallizer’s desks and suggested a laboratory device for that purpose. Research limitations/implications: Another solution will be focused on developing of diagnostics device into the operational conditions. Practical implications: These problems are solved with cooperation with regional metallurgical companies. Gained results will be applied into the operational conditions. Originality/value: In the frame of solution was created a catalogue of defects of crystallizer’s desks and methodology of evaluation of crystallizer’s desks states.
