Analysis and Discussion on Reasons for Strip Breakage and Fire Accident in C52100 Alloy Cold Rolling Process

Reasons of strip poor surface quality, strip breakage, strip breaking and catching fire of C52100 alloy when produced by a Sn-P bronze strip company were obtained by the way observing and analyzing in site, rolling test and comprehensive analysis of the theory of rolling process in this paper. Main reasons of the defect and accident of strip production are higher percentage composition of the hard particle Pb and higher reduction in pass. Current situation of the not very ideal mode and effect of rolling oil removing which is the ultimate reason of higher reduction in pass for cold finish rolling C52100 strip was also analyzed in the article.
