Rolling processes - Al-Mustansiriya University

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

The Hot Rolling Process - California Steel Industries

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

control plan examples — Control Plans

In the case of this control plan, a subgroup of five samples is pulled hourly and checked with a go/no-go functional gage. The results are then plotted on a p-chart, which is a percent-defectives SPC (statistical process control chart). This is a weak process control step and would produce a high risk-priority-number on a PFMEA.

Rolling Mills | Industrial Efficiency Technology & Measures

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...
