The hot metal is passed between two rolls to flatten it, lengthen it, reduce the cross-sectional area and obtain a uniform thickness. Hot-rolled steel is the most common product of the hot rolling process, and is widely used in the metal industry either as an end product or as raw material for subsequent operations.
Today, cold and hot strip mills around the globe are continuously looking for ways to increase their productivity, save energy, lower their overall costs and improve the final quality of their products. Using lubricant in cold rolling and controlling the roll-wear in hot rolling are some of the ways to achieve these goals.
When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.
Hot rolling mill More high-quality output with optimized solutions for hot rolling mills Despite the everyday challenges of heat, lots of cooling water and high-impact forces, hot rolling mills are expected to continuously increase output while maintaining and improving the quality of the finished product.
Turn-key hot rolling mills Technology and Reliability in Rolling Mills for Long Products Latest technology and high productivity of our plants: guided by these concepts, we supply a complete scope of any green-field rolling mill for long products, as well as upgrading of existing plants.
STECKEL MILL — SPECIALIZED SOLUTIONS THROUGH ENGINEERING EXPERIENCE The Steckel Mill occupies a special niche in hot flat rolling, operating at a lower economic volume than tandem hot strip mills but capable of greater widths and especially suitable for particular alloys, including stainless steels.
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.
In the hot rolling process, the slab is mainly made of continuous casting slab. After heating, the strip is made of cold rolling mill and hot rolling mill. The finished steel of hot rolling mill is cooled to laminar flow to establish temperature band.

(Roll forming: )This film takes you through the processes within a hot rolling mill. You'll get to see the different stages all th...
Hot rolling mills typically produce sections of steel at various dimensions from billets of steel. The manufactoring process involves passing bars of steel at high temperatures. This happens through rotating rolls to reduce the thickness and shape the sections. It furthers proceeds into cooling and cutting to length or coiling into rolls for ...

4-Hi/6-Hi Tandem Hot Strip Mills: Magadh can offer 4-Hi/6-Hi Tandem Hot Strip Mills (5 Stand or 6 Stand) for strip width upto 1670 mm, 900 MPM speed and …
Hot Rolling Mills Warehouses - ENSIDESA. Industry. Metallurgy. In 1953, the silhouette of the large buildings of the iron and steel factory began to be seen on the Avilés horizon. Then, the work on prospecting the land in the area bordering Corvera began to proceed with the construction of the hot-rolling warehouses.
IMS product portfolio for cold rolling mills, hot rolling mills, aluminium rolling mills, casting mills, coating lines and metal service centres.

Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills. In smaller operations the materials start at room temperature and must be heated either in a soaking pit, or by induction heating before being fed into the mill. Hot rolling improves: Toughness and strength
1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.
3.1.1 Hot rolling ... cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 50-75 mm. 2. First intermediate roll (tapered), diameter between 90 …
Oils, soap emulsions, fatty acids are used as lubricants during hot rolling non-ferrous metals. Mineral oils, paraffin, fatty acids are used for cold rolling. Normally, foe ferrous alloys no lubricant is used. 1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills.
Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip
Hot rolling mills roll heated steel, stainless, and aluminum slabs to make hot strip with a thickness of a few millimeters to over ten millimeters. Hot coils are shipped as they are, or moved to another operation and processed to cold rolled sheet, coated steel sheet, or steel pipe.
There are certain types of the rolling process, whereas, in the hot rolling process, the metal is heated at its desirable temperature, when the metal is properly heated then the metal should be passed between the one or more rolling mills to gain the proper desirable shape. This process is vastly used in respect of any other rolling process.
HOT ROLLING MILLS. In a hot rolling mill process, the steel gets heated at extremely high temperature, which is generally above 1100°C. BLH Nobel can provide sensors and complete measurement systems that are highly durable and withstand the extremely harsh environment in the steel industry production sites.
Rolling Mills Rolls. Rolling had assumed importance in the industrialized world during the nineteenth century. Profiles and flats are hot rolled while some flat products are also cold rolled. Rolls are tools in the rolling mill. The weight of the rolls can vary from a few kilograms to as high as 250 tons.
