Description
Przedmiotem wynalazku jest stop na rdzenie walców hutniczych zespolonych, stosowanych do walco¬ wania blach stalowych w sposób ciagly.Znane sa rdzenie walców hutniczych zespolonych wykonane ze stopu zawierajacego wagowo: wegla 3,25-3,50%, manganu 0,25-0,45%, krzemu 0,8-1,0%, fosforu 0,4-0,5%, siarki max. 0,06%, reszta zelazo.Intensyfikacja procesu walcowania, ciezkie warunki pracy oraz niestabilnosc w systemie chlodzenia powo¬ duja, ze rdzenie walców nie spelniaja stawianych im warunków, skutkiem czego wystepuje pekanie walców oraz lamanie czopów, Kryteria okreslajace warunki techniczne walców ujete sa w BN—65/0673—01.Istota wynalazkujest opracowanie nowej receptury stopu na rdzenie walców hutniczych zespolonych, w której poprzez odpowiedni dobór i zawartosc pierwiastków stopowych uzyskuje sie stop o zalozonych wlasnosciach. Stop na rdzenie walców hutniczych zespolonych zawierajacy wagowo 1,4-1,75% krzemu, max 0,17% fosforu, max 0,05%, oraz wegiel, mangan, chrom i molibden, reszta zelazo i nieuniknione zanieczy¬ szczenia, wedlug wynalazku zawiera wagowo 2,86-3,1% wegla, 0,4-0,7% manganu, max 0,25% chromu, 0,8-1,2% niklu, 0,15-0,35% molibdenu, 0,002-0,006% strontu, 0,001-0,006% bizmutu.Stop wedlug wynalazku gwarantuje wysokie wlasnosci wytrzymalosciowe, odpornosc na pekanie wal¬ ców oraz lamanie czopów. Dobór skladników w stopie na rdzen uszlachetniony strontem i bizmutem powoduje rozdrobnienie struktury, co w efekcie zwieksza wytrzymalosc rdzenia i czopów. Przykladowo stop na rdzenie walców hutniczych zawiera wagowo: 2,90% wegla, 0,65% manganu, 1,60% krzemu, 0,12% fosforu, 0,46% siarki, 0,20% chromu, 1,15% niklu, 0,30% molibdenu, 0,003% strontu, 0,0026% bizmutu, reszta zelazo. Stop ten posiada twardosc 26 stopni Shore'a.Zastrzezenie patentowe Stop na rdzenie walców hutniczych zespolonych z nieokreslona warstwa utwardzenia, stosowanych zwfaszcza w walcowaniach blach stalowych, zawierajacy wagowo 1,4-1,75% krzemu, max. 0,17% fosforu, max. 0,05% siarki oraz wegiel, mangan, chrom, nikiel i molibden, reszta zelazo i nieuniknionezanieczyszcze¬ nia, ZB&mtenay tym, ze zawiera wagowo 2,86-3,1% wegla, 0,4-0,7% manganu,max. 0,25% chromu, 0,8-1,2% nikhi, 0,15-0,35% molibdenu, 0,002-0,006% strontu, 0,001-0,006% bizmutu.
