Development of preventive maintenance : case study a steel mill ; Ehkäisevän kunnossapidon kehittäminen : case-esimerkki terästehdas
The aim of this thesis is to develop and modernize the preventive maintenance of Ovako Imatra steel mill as part of the renewal project of the maintenance management system. Current preventive maintenance plans of the mill are partly outdated, in addition to which failures are to be anticipated and prevented by various risk analysis methods. Aim is to reduce failures, identify the most critical equipment and components and improve mill reliability by optimizing preventive maintenance. Triangulation components are used as research methods; literature review, risk analysis methods and databases of Ovako. Thesis is limited to the mechanical equipment of the steel mill and heavy bar mill. Thesis determinates the most faulty equipment in the mill based on mechanical failure information. Criticality classification of equipment, as well as failure mode and effects analysis, provide methods to develop preventive maintenance in the direction of reliability centered maintenance (RCM). The optimization of preventive maintenance instructions ensures the need for preventive maintenance of the current equipment base, aiming to correct maintenance intervals and minimize failures. In the results of the thesis, the most faulty areas and equipment were determined for case examples (PSK6800 and FMEA). Criticality classification of equipment and FMEA were used to assess the criticality of the most faulty equipment and possible failure modes and their effects. Information from case examples, my own experience and literature review materials were utilized in the optimization of preventive maintenance instructions. Optimizations were completed for the new maintenance management system, Pinja Novi. ; Tämän tutkimuksen tavoitteena on kehittää ja uudistaa Ovako Imatra terästehtaan ehkäisevää kunnossapitoa osana kunnossapitojärjestelmän uudistamisprojektia. Tehtaan nykyiset ehkäisevän kunnossapidon ohjelmat ovat osittain vanhentunutta tietoa, jonka lisäksi vikaantumisia halutaan ennakoida ja estää eri riskianalyysimenetelmin. Tavoitteena ...
