Assessment of the Operational Durability of Graphitized Electrodes Using the FMEA Method
摘要
The problems that arise during the operation of electrode products in arc steel‑making furnaces are considered. Some causes of increased consumption of graphitized electrodes during steelmaking are analyzed in detail. The FMEA methodology (Failure Mode and Effect Analysis) is widely used to analyze types and consequences of failures; it enables minimizing the time required for analysis, simplifying documentation, and reducing ambiguities in risk criteria. It is shown that FMEA analysis data can be used to reduce the specific consumption of graphite per ton of steel produced. Prioritizing problems makes it possible to implement changes and corrective actions not only in the steelmaking technology but also in the preparation of graphitized electrodes and stubs. This will improve the quality of delivered electrode products and raise customer satisfaction while minimizing losses of material and human resources.
