Kun tarvitaan ohuempaa levy\u00e4 tai parempaa pintaa kuin mit\u00e4 kuumavalssauslinjalla tuotetaan, levy t\u00e4ytyy kylm\u00e4valssata.<\/p>\n

L\u00e4ht\u00f6kohtana k\u00e4ytet\u00e4\u00e4n kuumavalssattua aihiota ja prosessi aloitetaan materiaalin ollessa kuumentamatonta, mist\u00e4 johtuu nimitys kylm\u00e4valssattu. Kylm\u00e4valssauksen j\u00e4lkeen materiaali hehkutetaan. Kylm\u00e4valssattua materiaalia voidaan ohjata niin, ett\u00e4 se on joko eritt\u00e4in muokattavaa \u2013 pehme\u00e4\u00e4, tai eritt\u00e4in lujaa \u2013 kovaa.<\/p>\n

Kylm\u00e4valsattua myymme normaalisti paksuuksina 0,5\u20133,0 mm, mutta sit\u00e4 voidaan tilata sek\u00e4 ohuempana ett\u00e4 paksumpana.<\/p>\n<\/div>\n<\/div>\n
