The paper's contribution is the description of a methodology for the development of object-oriented DTs, interlinked in the process, exemplified by a rolling mill coiler.
These mills are normally two-high reversing mills with 0.6-1.4 metres diameter rolls (designated by size). The objective is to breakdown the cast ingot into blooms or slabs for subsequent finishing into bars, plate or a number of rolled sections. The blooms/slabs are heated initially at 1100 0 C-1300 0 C.
Mills have been supplied for both continuous strip and cast ingot. Strip rolling is the mechanical process of reducing the gauge thickness of plate or sh...
In the case of high-strength steel rolling, there is a requirement for making reduction to ordered gauge on rolling mills with a higher number of stands. Figure 1 shows a five-stand cold-rolling tandem mill in which the presented research was carried out. Entry maximum thickness of strip is 3.8 mm exit thickness is maximum 1.75 mm, …

Bar rolling is a semi-continuous rolling process involving a series of rollers, where a cast billet is shaped into the final TMT bar. In these mills, low-thickness bar rolling (< 20 mm) is prone to cobbles, due to several operational reasons, which affects productivity. One major contributor is blockage of slitters and no-twist mill grooves due to …

Abstract. Modern steel production centers on the hot rolling mill as a key component. Scheduling for hot rolling mills is a challenging problem that has fascinated …
Steckel mill, also known as a reversible finishing mill is like a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill; therefore, the process is more like drawing than rolling.
Steel rolling is a metalworking process that involves shaping metal by passing it through pairs of rolls to reduce thickness and alter the cross-sectional area. The primary goal of steel rolling is to produce finished products with desired dimensions, surface finish, and mechanical properties. The process is widely used in the production of ...
This paper has presented a computer control system for aluminium single-stand 4-high cold rolling mill. The 3-level automation system can significantly improve the dimensional accuracy of the aluminium strip, quickly adapt to the changes in rolling specification, and significantly improve the mechanical properties of the steel plate.
Abstract. Aiming at the complex changes of the working rollers and rolled pieces in the. rolling process of a cold rolling mill, this paper built a finite element model of the working. rollers and ...

Cold rolling process is a technique which is mostly applied for the production of smaller sized products with high strength, these products are achieved by including cluster mills as shown in Fig. 3, it does not reduce the thickness as much as hot rolling [11].The considerations are met, when the metal pieces are "worked" at temperature …
Release time: 2024.01.23. . Steel rolling mill machinery plays a crucial role in the steel manufacturing process. It is specialized equipment used to shape and transform raw steel into various finished products, such as sheets, plates, bars, wire, and structural sections. The machinery employs a process called rolling, which involves passing ...
Calibre rolls have wear resistances of about several hundreds tons of hot rolled steel per millimetre of machined roll diameter (ton mm-'), whereas typical flat rolls have "lives" of about 5 X 103-20X lo3 ton mm-' [1,7,8]. Such a variety of roll wear criteria makes objective comparison of roll performances difficult.
