The hot metal is decarburized to the required carbon content in the BOF. The main reaction in this process is the oxidization of the carbon in the hot metal by both pure oxygen gas (O 2) and iron oxide (Fe 2 O 3). The residual oxygen, after contributing to this decarburization reaction, remains in .

Cold rolling mill process diagram In the cold rolling mill the hotrolled strip is reduced to the requested thickness at room temperature, slit or cut to length and rewound into coils. This coldrolled strip steel is frequently used within the automotive industry, by automotive suppliers, in metal processing and in the electrical industry.
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 (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required. Hotrolled metal is generally free of ...

The rolling process is shown in Fig. : 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.
The hot metal is converted into steel through a steelmaking process called the LD process. Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill. Long Products:
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
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 semifinished products

Thanks to integrated process models today''s demands for flexible and economic production of steel plate can only be met by electrical and automation solutions based on technological process modeling, highperformance control systems, and a comprehensive understanding of hot rolling technology.
The process for the production of Kraftliner and Semichemical Fluting starts with wood coming from the forest to the mill. Most of the wood is delivered to the mill in the form of pulpwood logs but also a substantial part is brought as wood chips from saw mills nearby. The pulpwood logs have to be debarked and chipped before further processing.

P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005. Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap.
