Among them, the two-high Pilger cold-rolling mill is most widely used, which is based on the two-high cycle Pilger mill. In the rolling process of the two-high Pilger cold-rolling mill, the steel pipe is repeatedly rolled in the annular pass composed of the circular groove at the varying section and the fixed tapered plug.
The hot rolling technology is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other industries. In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the …

When I received this mill I hadn't used one regularly since college (2004- 2007), so I thought I should do a deep dive into all the benefits and uses. Intro to the rolling mill. This first post was about the proper securing and care of my @pepetools_usa 130MM Single Combo Rolling Mill #189.20A

The chromium in stainless steels is primarily responsible for the self-passivation mechanism. In contrast to carbon or low alloy steels, stainless steels must have a minimum chromium content of 10.5% (by weight) of chromium (and a maximum of 1.2% carbon). This is the definition of stainless steels given in EN 10088-1.
This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold …
The rolling speed at which the productivity is maximum is conventionally called the critical rolling speed v cr.The value of v cr depends on the coefficients c 1 –c 7, which are determined by the parameters of each group of mills (thickness and width of rolled products, roll change rates, rolling cycle components, etc.).The study of the influence of …
When the material arrives at the cold rolling mill it is covered in black scale and is sent through an annealing and pickling line to remove it.

Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling …
Keywords: rolling mill, rolling speed, coil weight, mill productivity, strip thickness and width DOI: 10.3103/S0967091220050125 INTRODUCTION The need to expand production and improve the quality of thin-sheet cold-rolled metal requires the improvement of existing broad-strip cold rolling mills and creation of new high-performance and economi ...
In the continuous production line with pickling, tandem cold mill, and continuous annealing line, the task of the pickling line is to clean the steel plate before cold rolling to remove surface inclusions and oxides, and the solution used is 3–5% hydrochloric acid. The task of the tandem cold mill is to carry out cold rolling of hot-rolled ...
The steel industry has had a long history of development, yet, despite all the time that has passed, it still demonstrates all the signs of longevity. The steel industry is expanding worldwide. The economic modernization processes in these countries are driving the sharp rise in demand for steel. Rolling is a metal forming process in which metal stock is …
The sample was 200 mm in length and 100 mm in width, and was rolled by a two-high rolling mill at room temperature. The rolling reduction was 45%, with interval of 15% by three passes. The cross-sectioned samples were prepared to conduct metallography, electron backscatter diffraction (EBSD) and tensile tests by wire-electrode …
The microstructure of a low Si, ultra-low-C, hot-rolled electrical steel strip is modified by annealing at T < To, the α→γ transformation temperature. This heat treatment causes the abnormal anisotropic growth of surface grains which consumes the original hot-rolled microstructure. The growth of the surface grains first takes place parallel to the …
Abstract and Figures. The state-of-the-art of both technology and operational practice of a hot rolling mill are discussed. The focus is first on the control of entry temperature in the finish ...
The accumulated results and the analysis of more than 1000 technological modes of rolling of carbon steel with a thickness of 0.48–1.21 mm and a width of 915–1211 mm in the 1700 continuous cold-rolling mill make it possible to formulate the mechanisms of initiation of the negative vibrations as follows:
The final cold rolling flattens the grains, strain hardens the material (i.e., forms a typical dislocation/sub-grain structure), generates the typical fcc rolling texture, and further crushes and aligns the particles. In cold rolling base oils with a low viscosity from 1.5 to 4 mm 2 s −1 and additives are used for lubrication and cooling ...
