Implementasi Failure Mode and Effect Analysisis (FMEA) dan Diagram Pareto untuk Analisis Kegagalan Komponen Continuous Casting Machine pada Perusahaan Baja

Abstract

Steel companies are one of the manufacturing companies that play an important role in the Indonesian economy. In the production process, these companies use various production machines, one of which is the Continuous Casting Machine (CCM). CCM is one of the most important machines in steel companies because it is a steel molding machine which determines the success of steel production. In its use, CCM often experiences failures that hinder the production process and cause material losses for the company. To overcome these problems, this research uses the Failure Mode and Effect Analysis (FMEA) method to analyze failures in CCM components, identify failure modes and their impacts, and conduct risk assessments using the Severity, Occurrence, and Detection (SOD) multiplication approach. In addition, Pareto diagram analysis was conducted to determine critical components, so that the company can prioritize maintenance activities and improve CCM reliability. FMEA analysis showed that out of 14 main components with 41 subcomponents, there were 59 failure modes. The tundish component was identified as the component with the highest Risk Priority Number (RPN) of 350, with the failure mode of tundish leakage. Further Pareto diagram analysis highlighted 4 critical components, including tundish, roll (mold), roll (roll apron), and roll press. The insights gained from this analysis are expected to enable the company to maintain CCM reliability and prioritize maintenance efforts on identified critical components, thereby mitigating the impact of potential failures.
