Influence of longitudinal cold rolling on the surface topography of low carbon structural steel

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.The paper presents a method of surface evaluation of steel strips formed by longitudinal cold rolling, carried out by a rolling mill DUO 210 SVa. The experiments were performed on samples of low carbon structural steel in order to determine the impact of grain size of material with respect to technological parameters, particularly with respect to a rolling reduction and rolling force. Surface roughness of the steel strips was measured at three locations by an optical profilometer MicroProf FRT. These results were consequently mutually compared
