1.2 Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. 1.2.1 Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature. The advantage of hot rolling is twofold.

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. Rollers may be plain or grooved depends upon the shape of rolled product.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 1.2.5 Cooling. After exiting the finishing mill, the strip, at a temperature of 800–900°C, is cooled further under controlled conditions by a water curtain on the run-out table.The run-out table may be as long as 150–200 m. Cooling water is sprayed on the top of the steel at a flow rate of 20,000–50,000 gpm; and …

For the production of cold rolling steel strips in a yearly production capacity range from 150,000 to 300,000 tons, a reversing cold rolling mill, which requires relatively minimal capital investment, is put into use. The reversing cold rolling mill is used mainly for producing coils of ordinary carbon steel in

During the process of cross rolling the rolls are rotating in the same direction. The billet is fed in axial direction and it re-ceives the rotational movement contacting the rolls. The billet is retained in rolls by special device during the process of rolling and reducing by rolls. The sections being the bodies of revolu-

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the …
