Abstract [en]

The present study tests different roll materials and lubricants for cold rolling, using a strip reduction test equipment at The Technical University of Denmark. Aims was to study the roll/tool material wear resistance and the resistance towards galling, i.e. lubricant film breakdown causing pick-up of work piece material on the roll surface and subsequent scoring of work piece surfaces. The four industrial lubricants investigated all consisted of mineral oil with fatty acid additives. The work piece material was stainless steel, AISI 304. The materials tested were NARVA 12B from Åkers, using the cold work tool steel SVERKER 3 from Uddeholm (AISI D2), SUPRA 3 from Åkers using the PM tool steel VANADIS 23 from Uddeholm and Åkers special finely distributed carbides and nitrides tested roll material, using an anti-seizure PM tool steel VANCRON 40. Evaluation of resistance to wear was done; during 20 % strip reduction NARVA 12B/SVERKER 3 showed a low surface roughness when lubricant “A” was used and during both 10 % and 20 % strip reduction VANCRON 40 showed a low surface roughness when lubricant “C” was used. Together with the lubrication the surface topography of the roll material is expected to influence friction. Evaluation of resistance to galling was done. Results showed VANCRON 40 to be especially prone towards galling.
