Abstract: Features of Maintenance, Repair and Overhaul (MRO) service in continuous casting equipment and its knowledge management were discussed. After analyzing significance of constructing MRO knowledge model by ontology, based on the three-layer construction including meta-ontology, domain ontology and application ontology, an idea of using Web Ontology Language(OWL) to construct MRO knowledge model was proposed. With simple and reasonable logic feature of ontology, it was used to represent general rules in top abstraction layer. Based on meta-ontology, domain ontology was constructed with MRO domain knowledge structure. Corresponding knowledge models such as equipment structure, equipment status, equipment failure and MRO business process were set up oriented to MRO business in iron and steel continuous casting equipment. Finally, configurable process example based on MRO knowledge model was discussed to promote knowledge sharing and reuse in MRO field.
