By default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...

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, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...

Beam-blank casting results in fewer passes in the section mill, reduced energy use and lower production costs. Near-net-shape casting is an energy-saving alternative to conventional bloom casting for the production of beams and sections. The greatest benefits can be derived through the direct coupling of the caster to the rolling mill.

Work roll life of hot rolling mills is strongly affected by roll material. Recently, high-carbon high speed steel rolls have been developed to improve further work roll life. In this paper, relationship between basic characteristics of roll and microstructure in high …

The 1780 mm hot strip mill of Chengde Iron and Steel Co. is taken as our research object, which vibrates violently with huge noise. In order to study the instability state of rolling mill, the rolling mill vibration and the main rolling parameters of the second-stand rolling mill (Short for "F2") are tested and recorded, as shown in Fig. 1 ...

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
