Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes.This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated with polishing, industrial etching, or some other surface ...
The backup rolls are normally made of softer material than the work rolls to prevent work roll markings. The four-high mill stand is the most popular type of mill stand in use since it can be used for many production steps such as breakdown rolling, finish rolling, and temper rolling. Typical 4-high stands showing various details are shown in ...

Stable operation of the finishing mill through higher temperature and uniform temperature over the whole length of the transfer bar. Due to this feature zoom rolling in the finishing mill is not required; Passing through the coil box without coiling is selectable according to the required production and operation methods
The final shaping stage of a hot rolling steel strip is normally performed on a tandem mill known as a finishing mil. Hot Strip Mill Group consists of two to six finishing mill stands, which reduce the thickness of the transfer bar to meet the customer demanded standard-sized or the next process.
Steel rolling mill product finishing pro cesses gradually become or often already are unsuited for current production and marketing conditions. Indications are made as to what has been done to (i) rectify situations of this kind and, (ii) to reduce both product finishing time and costs. The principal features of two separate case studies are reviewed, these being (a) the finishing …
Finishing block mill comprises bevel-type gear in gearbox that is made of superior grade forged steel. The finishing block mill is located in the high-speed wire rod workshop. Rolling by 10 units rack continuous micro-tension rolling mill, rolling the Φ17~Φ21 mm of rolled piece transported from upstream into Φ5.5~Φ16 mm finished wire rod.
Rolling Mill Stands are used to control the outer diameter of the pipe during the elongation and diameter finishing processes. Mill Stands in rolling mills consist of several components and systems, all of which are subject to high temperatures, high loads and extreme conditions.
Finishing Mills Finishing mill is the top cross 45° high-speed wire rod finishing mills designed for producing wire rod. Rolling by 10 unit rack continuous micro-tension rolling mill, the Φ17~Φ21 mm of rolled piece can be rolled into Φ5.5~Φ16 mm wire rod. The mill guaranteed exit speed is 90 m/s. (When the final wire rod size is Φ5.5 mm)
More than 90% of worldwide produced steel is solidified into a 'semifinished' billet, bloom, or slab for subsequent rolling in the finishing mills using the continuous casting process. Mould flux performs five basic functions ( Anon., 2011b ): 1. Thermally insulates the molten steel meniscus to prevent premature solidification. 2.
finish strip size based roll sizing for cold reduction. Finishing mills roll cold coils of, Sheet steel that has been pickled and run through a cold-reduction mill, Cold-Rolled Coil Hot Rolling Mill.
rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by Morgan-Sumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed qual-ity of products was shifted toward high-value-added special steel quality, and, to achieve this, in 1986, a three-roll finishing rolling
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.
to roll thin hot strip in a finishing mill of a CSP line and in a conventional hot-strip mill. The goal is to achieve improved strip thickness performance and operational stability. Primetals Technologies has developed a new control concept for rolling ultra-thin hot-rolled strip in the finishing mill of an ESP line.

The aim of the wear study is to develop an accurate roll-wear prediction for hot strip finishing mills, which takes more influential parameters into account. A new model of higher accuracy is presented. This model is based on a large amount of production campaigns. The strategy of the work is described below.
of rolling mills will find here the principles for selection and calculation of roll neck bearings. Their mounting and maintenance ... In the finishing sections of such lines with rolling speeds of up to 100 m/s and higher, rolling is carried out on a single strand. Normally, single row cylindrical

The finishing mills roll the rolling stock in tandem, meaning each bar is rolled through all finishing stands at once. Laminar cooling of the hot rolled strip: After exiting the finishing mills, the strip is carried down by a large number of individually driven rolls through banks of low-pressure, high-volume water sprays that cool the red-hot strip to a specified coiling …
