Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force applied through a set of rolls. The cross section of the slab is reduced by the hot rolling process.

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.
The hot strip mill process (HSMP) is a high-speed, transient metal machining molding process.1–3 In the steelmaking process, stable product quality and safe, reliable operation of a hot strip rolling mill are the main control objectives. The dimensional quality speci-fication,4 consisting of thickness, width, flatness, and
CSC's manufacturing process is composed of raw material preparation, ironmaking, steelmaking, and rolling. ... Slabs are fed into the plate mill to be rolled into plates or processed into hot rolled products in the hot strip mills. Hot rolled products can be further processed to produce cold rolled products in the cold rolling mills. Steelmaking .
The strip surface is oxidised. However, due to high rolling force, the surface granularity of hot strip is considerably reduced compared to slab. Cold strips are produced by rolling hot strips in cold rolling mill after pickling process (which removes the oxide layer and cleans the surface). Thus, the surface of cold strips is not oxidised, and ...
CSI's Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.
achieved through measurement of strip thickness using x-ray gage and adjusting the strip tension using feedback control system. 1.8 Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we
Hot Strip Mill Rolls. In the last twenty years, under the constant request for. stricter acceptance criteria of rolled product, the technical. innovations of work rolls in Hot Strip Mills have been focused. on the application and the improvement of HSS (High Speed. Steel) rolls. NSR has taken the initiative in the development.
The mechanical properties of hot rolled strip are the key index of product quality, and the soft sensing of them is an important decision basis for the control and optimization of hot rolling process. To solve the problem that it is difficult to measure the mechanical properties of hot rolled strip in time and accurately, a soft sensor based on ensemble local modeling was …
process flow. The interdependency of setup times, process flexibility and integration were analysed through system dynamics simulation. The results showed significant reductions of energy consumption and tied capital. It was concluded that setup time reduction in the hot strip mill can aid process integration and hence improve

Hot Strip Mill: Process : Continuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths.
The subsequent rolling operation in the high-speed tandem mill diminishes the interpass RX process while self-annealing might occur during the cooling of coiled hot rolled strip (35,36). The effect of strain mode and hot rolling parameters on the microstructure and texture evolution is summarized in Figure 4 .
What Is A Rolling Mill? 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. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

In these cases the first roughing stand of the hot strip mill was a broadside mill with entry and delivery slab turning tables or slab lift and turn mechanisms which were used to rotate the slabs 90°. The broadside mill then cross-rolled the slab in a …
In the manufacturing process of hot strip continuous rolling, it is one of key factors to ensure stability rolling and better quality of strip, to keep the relatively invariable strip tension between two stands. Draft compensation was adopted, which takes the initiative to compensate roller speed, in order to decrease the coupling effect of automatic gauge control subsystem, …

This process is now known as the continuous hot rolling process. At a pack mill, plates had to be run over the roll and doubled, making the process much slower and more labor intensive. The process used at a strip mill was preferred over the processes of the pack mill because the milling process was continuous.
Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semi-finished products
Inductive edge heating system. Excellent strip quality right to the edges. It's a huge challenge to avoid excessive tension at the strip edge during aluminum strip cold rolling. The conventional solution is the hot edge spray (HES) method of heating the work roll barrel. New on the market, our inductive edge heating system reduces strip tension.
The process of rolling, the contact of the roll with the rolled material is almost out of our reach: we cannot visibly watch, not ... Work roll in hot strip mills wear due to friction between roll surface and hot strip. (Back up rolls wear as well, but under
