2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...

Such rolling imparts high accuracy and surface integrity of the teeth which are formed by material flow unlike cutting. Gear rolling is reasonably employed for high productivity and high quality though initial machinery costs are relatively high. Larger size gears are formed by hot rolling and then finished by machining Version 2 ME, IIT Kharagpur

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating
The process of hot-rolled seamless steel pipe. Hot-rolled seamless steel pipe is generally produced on automatic rolling mill units. The solid bar is inspected and cleared of surface defects. Then it is cut into the required length, and centered on face of the perforation end of the pipe billet. And then it will be sent to the heating furnace ...
The same is shown in the flow chart. Classification of Rolling Process Rolling Process can be classified either i)based on the temperature of the metal during rolling or ii) based on the arrangement of the rolls and their number or iii)based on the Products rolled. i)based on the temperature: Rolling can be classified as Hot Rolling or Cold ...
The process is for cutting rough mother sheets TM issuing from a rolling mill into daughter sheets of predetermined dimensions. In the course of this process, there is determined the inscribability of each mother sheet so as to establish a marking plan permitting an optimum utilization of the sheet. Each mother sheet is passed through devices 5, 6 for cutting the sheet to dimensions and ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
