1. 1. Surface temperature measurement on a Yankee cylinder during operation

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap, fysik och matematik

   Författare :Henrik Jackman; [2009]
   Nyckelord :;

   Sammanfattning : The Yankee cylinder is used in most of Metso Paper's machines. It is used in the drying and creping process. Since the outcome of these processes largely affect the paper's final quality it is important that the Yankee cylinder behaves in a controlled fashion. LÄS MER

   Sammanfattning : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. LÄS MER
