rolling (metalworking) - wikipedia,in metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. the concept is similar to the rolling of dough.rolling is classified according to the temperature of the metal rolled. if the temperature of the metal is above its.minimizing wall thickness variation in seamless tubing,grip is defined as the number of tube spirals before the hump centerline in the cross-rolling elongator mill roll pass design—in simple terms, the pierced shell should contact the roll face early in the process so tube feed is established before it encounters the work zone in the hump section..crane rails - arcelormittal rails,crane rail. arcelormittal europe. long products - rails & special sections is leading company in delivery crane rails worldwide for port and terminal projects and industry with more than 30 different sections to offer to customers. arcelormittal is a crane rail supplier & manufacturer.. our rolling mills produce environmentally friendly steel and are strategically located to serve their.product guides - central steel,a temper mill is a steel sheet and/or steel plate processing line composed of a horizontal pass cold rolling mill stand. goal is to correct shape differences along the width of the coil through cold forming. the end results/advantages of temper passing and leveling are listed below. thickness dimension more consistent across the width.
