20.500.12556/DKUM-12909 UPORABA IN RAVNANJE S HLADILNO MAZALNIMI SREDSTVI APPLICATION AND CONTROL OF THE LUBRICANTS V kovinsko predelovalni dejavnosti se pri postopkih obdelave kovin uporabljajo hladilno mazalna sredstva (HMS), ki so potrebna za nemoteno delovanje obdelovalnih strojev ter hlajenje, mazanje in odvajanje nečistoč. Pri delu s HMS moramo upoštevati predpise in zahteve za varstvo okolja, razpoložljivost surovin, delovno higieno, varnost za uporabnika in nenazadnje zniževanje stroškov. Za zagotavljane čim bolj gospodarne uporabe je potrebno kakovost HMS sistematično in periodično kontrolirati. Namen diplomskega dela je vzpostaviti takšen sistem ravnanja s HMS, ki bi z redno kontrolo zmanjšal porabo sredstev, izboljšal učinek obdelave, minimiziral odpadke in stroške vzdrževanja strojev in zastojev. V podjetju Unior d.d. smo se nadzora nad HMS lotili tako, da smo najprej vzpostavili kontrolo nad sredstvi v obratu Strojne opreme. Iz rezultatov merjenj smo ugotovili, da imajo HMS, ki jih periodično preverjamo bistveno daljši rok trajanja kot sredstva, ki jih preverjamo samo takrat, ko nastopijo težave in je zato moten delovni proces. Zato je ključnega pomena, da sistem ravnanja s HMS vzpostavimo v vseh obratih, kar bo nedvomno imelo za posledico ekološki in ekonomski učinek Metalworking fluids (MWF) used in metal industry are composed of oil, water and additives and are able to provide the lubrication, cooling, corrosion inhibition and chip flushing. The legislation obliges users to keep MWF in faultless condition due to labour and environmental protection. The following technical criteria have an important role on MWF selection: environmental protection, raw materials availability, working hygiene, users safety requirements and cost minimization. The purpose of this diploma work is to establish the MWF management system, which would include regular monitoring with intention to reduce the consumption, improve effectiveness of the working process, minimize maintenance and waste costs. The first operating step needed to maintain MWF was to establish MWF management system in one department of “Strojna oprema” Plant of the factory Unior Zreče. On the basis of results achieved we can conclude, that monitoring of MWF prolonged their lifetime. We can summarize that established MWF management system resulted in ecological and economical efficiencies. Therefore, such system should be established in all factory plants. hladilno mazalna sredstva HMS emulzije maziva ravnanje s HMS obvladovanje HMS maziva gospodarjenje s HMS odstranjevanje HMS predelava HMS metalworking fluids MWF emulsions lubricants using and maintaining metalworking fluids operating life of metalworking fluids disposal and recovery of waste metalworking fluids true true false [A.
