How to sort out undesired bars (English)
Abstract [sv]

Projektet har utförts i samarbete med Ovako Hällefors. Närmare bestämt deras mediumvalsverk. Efter att stängerna valsats till önskad dimension, svalnar de en tid för att sedan klippas till önskad kundlängd. Efter klippning förs stängerna via en rullbana till fickor där de buntas. En del stänger är avvikande gällande längd och rakhet. I dagsläget sorteras de ut manuellt. En tidskrävande process då buntarna måste öppnas och de avvikande stängerna sorteras ut.

Företaget hade en önskan om att sortera ut dessa stänger redan i den befintliga produktionslinan. Projektet har undersökt och tagit fram två koncept på hur en lösning på problemet kan se ut.

En designprocess har legat till grund för projektet, innehållande: förstudie, analys, idégenerering och konceptframtagning. Där metoder så som deltagande observation, brainstorming, urvalsmatriser och dimensionering varit av stor vikt.

Projektet resulterade i två stycken koncept, ett baserat på processutveckling och ett på produktutveckling.

Abstract [en]

The project has been carried out at Ovako Hällefors. More specifically, their medium-rolling mill. After the bars are rolled to the desired dimension, they cool down for a time and then they get cut to the desired customer length. After cutting, the bars are transported to pockets where they are bundled. Some bars differ in length and level of straightness. Currently, they are sorted out manually. A time-consuming process since the bundles must be opened and the bars that differ are sorted out.

The company had the desire to sort these bars out already in the existing production line. The project has investigated and developed two concepts on how a solution to the problem may look.

A design process has laid the foundation for the project, including: preliminary study, analysis, idea generation and conceptualization. Where methods such as participant observation, brainstorming, selection matrices and calculating dimension has played a key role.

The project resulted in two concepts, one based on process development and one product development.
