Full-hard rolling reduces the thickness by 50, while the others involve less of a reduction.Skin-rolling, also known as a skin-pass, involves the least amount of reduction 0.5-1. It is used to produce a smooth surface, a uniform thickness, and reduce the yield point phenomenon by preventing L ders bands from forming in later processing.

Tandem rolling can be even more advantageous when integrated with continuous casting. The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling.
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
Rolling of Metals Process and Principles With Diagram The rolling process is shown in Fig. 2.1 Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. More Details ...

rolling mills can be achieved, then in some cases, cold rolling is not even required, which can result in a radical decrease of production costs. The schematic structure of a typical aluminum hot reversing rolling mill can be seen in Figure 1. The aluminum slabs, which have to be rolled, are transported
The cold rolling process provides a more refined surface, improved mechanical properties and excellent thickness product precision. Cold rolling mills are largely divided into the TCM Tandem Cold Rolling Mill and the RCM Reversing Cold Rolling Mill. In the TCM, material passes 5 or 6 rolling mills continuously to obtain the desired ...
