These castings are rolled to the required dimensions by the rolling mill to produce steel products. The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3 ) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel.
The Cold Drawing Process for Steel Bars and Wire. Raw Stock: Hot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.
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 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.
"Rolling mill" redirects here. For mills that use rollers to crush grain or stone, see roller mill. Rolling visualization. (Click on image to view animation.) 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 and to make the thickness uniform.

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 time of holding [35].
3/31/2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.
For cold rolling the strain hardening of aluminium alloys is an important aspect in processing control and sheet properties (see Chapter 11 of this book). For (technically) pure aluminium and some typical non-heat treatable Al-Mg-Mn sheet alloys, the flow stress evolution (i.e. strain hardening) is shown in Fig. 23.10 as function of cold rolling strain up to high rolling strains (90% reduction).

This makes cold rolling a more labor intensive and expensive process than hot rolling. Cold rolling can also reduce the grain size of the metal resulting in Hall-Petch Hardening. Both hot rolling and cold rolling are used to create sheet metal. However, cold rolling produces thinner sheets.

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 Pickled coils are cold rolled on 4 Hi AGC cold rolling mill to obtain the required thickness and annealed in HSD fired bell-type annealing furnace for bright annealing. In case of medium and high carbon coils, the process of rolling and intermediate annealing can be repeated to a number of times depending upon the final thickness to be ...
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.
Bars are produced in fully automated Re-Rolling Mills. The Captive Power Plant of 12MW (synchronized with PDB grid) and the National Grid are the sources of electricity of the factory. Fig: Production Flow Chart . Once the bars are cooled, they are cut into desired length by means of cold shearing.
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
