Abstract

U radu je prikazana metoda procjene površine ploče formirane uzdužnim hladnim valjanjem, obavljenim pomoću valjaoničkog stana 210 DUO SVa. Izvedeni su pokusi na uzorcima niskougljičnih konstrukcijskih čelika, kako bi se utvrdio utjecaj dimenzije zrna materijala s obzirom na tehnološke parametre, a posebice s obzirom na redukciju valjanja i silu valjanja. Hrapavost površine ploča mjerena je na tri mjesta optičkim profilometrom MicroProf FRT. Zbog toga su ovi rezultati međusobno uspoređeni.

Keywords
