Statistical Processing of Damages on Seamless Tubes

The paper includes statistic processing of frequency of damages on seamless tubes manufactured in 1998. and 1999. by the seamless tubes rolling mill at "Željezara Sisak". Cards xi, Parcto-chards as well as other statistic indicators and factors that show the stability of the process are presented. Based upon research results it may be assumed that the frequency of demaged tubes is less that expected by the monitored technological process. Consequently, the development trends - with regard to the frequency of damaged tubes - are positively directed.
