N\u00e4r man beh\u00f6ver tunnare pl\u00e5t eller om man beh\u00f6ver en finare yta \u00e4n vad som produceras i en varmvalsstr\u00e4cka, m\u00e5ste pl\u00e5ten kallvalsas.<\/p>\n

Man utg\u00e5r fr\u00e5n ett varmvalsat \u00e4mne och startar processen n\u00e4r materialet inte \u00e4r upphettat, d\u00e4rav namnet kallvalsat. Efter kallvalsningen gl\u00f6dgas materialet. Kallvalsat material kan styras s\u00e5 det antingen \u00e4r v\u00e4ldigt formbart \u2013 mjukt, eller v\u00e4ldigt h\u00e5llfast \u2013 h\u00e5rt.<\/p>\n

Kallvalsat s\u00e4ljer vi normalt i dimension 0,5 \u2013 3,0 mm. Men g\u00e5r att best\u00e4lla b\u00e5de tunnare och tjockare.<\/p>\n<\/div>\n<\/div>\n
