InDEx – Industrial Data Excellence

InDEx, the Industrial Data Excellence program, was created to investigate what industrial data can be collected, shared, and utilized for new intelligent services in high-performing, reliable and secure ways, and how to accomplish that in practice in the Finnish manufacturing industry.InDEx produced several insights into data in an industrial environment, collecting data, sharing data in the value chain and in the factory environment, and utilizing and manipulating data with artificial intelligence. Data has an important role in the future in an industrial context, but data sources and utilization mechanisms are more diverse than in cases related to consumer data. Experiences in the InDEx cases showed that there is great potential in data utili zation.Currently, successful business cases built on data sharing are either company-internal or utilize an existing value chain. The data market has not yet matured, and third-party offerings based on public and private data sources are rare. In this program, we tried out a framework that aimed to securely and in a controlled manner share data between organizations. We also worked to improve the contractual framework needed to support new business based on shared data, and we conducted a study of applicable business models. Based on this, we searched for new data-based opportunities within the project consortium. The vision of data as a tradeable good or of sharing with external partners is still to come true, but we believe that we have taken steps in the right direction.The program started in fall 2019 and ended in April 2022. The program faced restrictions caused by COVID-19, which had an effect on the intensity of the work during 2020 and 2021, and the program was extended by one year. Because of meeting restrictions, InDEx collaboration was realized through online meetings. We learned to work and collaborate using digital tools and environments. Despite the mentioned hindrances, and thanks to Business Finland’s flexibility, the extension time made it possible for most of the planned goals to be achieved.This report gives insights in the outcomes of the companies’ work within the InDEx program. DIMECC InDEx is the first finalized program by the members of the Finnish Advanced Manufacturing Network (FAMN, www.famn.fi).</p

Nosturin ja nostovaunun yksi- ja kaksilaippaisten kantopyörien materiaalivalinta

In this thesis different materials and manufacturing methods are research in order to find an alternative solution to manufacture bearing wheels for Electric overhead travelling crane. The purpose is to find out whether the currently applied EN-GJS-700-2 ductile cast iron is still the best solution for manufacturing bearing wheels or has the development of materials created a better solution. In addition for heavy use and process applications the currently applied tempered steel is compared to Austempered ductile cast iron (ADI). Thesis is mostly performed as a literature survey and information is searched also from other industries than crane industry. A major source of information is railway industry. Besides that the friction behaviour of ductile cast iron and steel is compared in combined rolling-sliding contact. This comparison is realized with laboratory tests performed by VIT. Test machine is Amsler type twin -disc-roller. This thesis research reveals that bearing wheels and their materials have not been researched in the field of crane industry. Casting appears to continue as the most suitable manufacturing method and no clear replacement for EN-GJS-700-2 is found. Solution strengthened ferritic ductile cast iron, EN-GJS-600-10, includes promising properties, but with current knowledge it cannot be applied without further researches. ADI proves to be superior to tempered steel by all compared properties. In laboratory test will be found out that ductile cast iron has lower coefficient of friction than steel in this type of contact. However, the measured values are higher than the design values given in standard. Coated materials appear to be promising in future. Based on the results of this thesis further researches in real operating environment of crane with ADI are recommended in order to replace tempered steel wheel with ADI wheels. Also further researches with GJS-600-10 are recommended.Tässä työssä tutkitaan siltanosturin kantopyörien valmistamiseen käytettäviä vaihtoehtoisia materiaaleja ja valmistustapoja. Tarkoituksena on selvittää tieto siitä, onko nykyinen EN-GJS-700-2 pallografiittivalurauta edelleen paras materiaali kantopyörien valmistamisessa vai löytyykö tähän tarkoitukseen parempia tapoja ja materiaaleja, joita tekninen kehitys on tuonut tullessaan. Lisäksi raskaampia nosturikäyttöjä varten vertaillaan nykyisin käytettyä karkaistua terästä austemperoituun pallografiittivalurautaan. Työ tehdään pääsääntöisesti kirjallisuusselvityksenä ja tarkoituksena on löytää uutta tietoa nosturialan lisäksi kaikilta muiltakin aloilta, joissa kosketus on hyvin samankaltainen. Suurimpana tällaisena referenssinä käytetään muuta kiskokalustoa, kuten rautateitä ja metroja. Tämän lisäksi verrataan pallografiittivaluraudan ja teräksen kitkakertoimia kosketuksessa, jossa on pyörimisen lisäksi luistoa mukana. Edellä mainittu vertailu tehdään käytännön mittauksin. VTT suorittaa mittaukset käyttäen koelaitteena Amsler-tyyppistä kiekkokulutuskonetta. Tutkimuksessa selviää, että nostureiden kantopyöriä ja erityisesti niiden materiaalivaihtoehtoja ei ole tutkittu kovin paljoa. Valaminen osoittautuu edelleen kannattavimmaksi valmistustavaksi ja selkeää korvaajaa EN-GJS-700-2 pallografiittivaluraudalle ei löydy. Liuoslujitettu pallografiittivalurauta EN-600-10 vaikuttaa potentiaaliselta haastajalta, mutta tämänhetkisen tiedon perusteella sitä ei voida ottaa käyttöön ilman jatkotutkimuksia. Austemperoitu pallografiittivalurauta osoittautuu ylivertaiseksi karkaistuun tierakseen nähden kaikilta ominaisuuksiltaan. Kokeissa pallografiittivaluraudalle saadaan mitattua pienempi kitkakerroin kuin teräkselle. Mitatut arvot ovat kuitenkin standardin antamia suunnitteluarvoja suuremmat. Pinnoitetut materiaalit vaikuttavat lupaavilta tulevaisuuden kannalta. Diplomityön tuloksien perusteella suositellaan jatkotutkimusta austemperoidusta valuraudasta tehdyille kantopyörille todellisessa nosturin käyttöympäristössä. Vastaavanlaisia kokeita suositellaan liuoslujitetusta valuraudasta tehdyille kantopyörille. Austemperoidusta valuraudasta tehdyillä kantopyörällä voitaisiin todennäköisesti korvata karkaistusta teräksestä valmistetut kantopyörät
