The warm rolling was performed at 200 °C in 6–7 rolling passes until a thickness reduction of 50% (1.5 mm) was achieved. The temperature-loss during transportation from furnace to rolling mill was 15 °C, which was determined by infrared thermography. The temperature loss was compensated by increased furnace temperature.
the Flex Mill. It consists of a thin-slab caster, a tunnel furnace, and a rolling mill with six stands and one downcoiler. Caster The cast slab thicknesses range from 55 to 85 mm (2.17 to 3.35 inches) and allow the mill to "flex" between heavy and light gauges, as well as meet reduction ratios required in producing demanding steel grades.

Medium diameter seamless pipe mill begins operation. Medium diameter ERW pipe mill (26''mill) begins operation. V-process casting equipment start up. Cumulative pipe production at Chita Works reaches 10 million tons. High grade special OCTG production equipment expanded. Development of numerical control (NC) rolling technology for seamless pipe.
The production flow treatment of intermediate demand is a stage-based system of price indexes. These indexes can be used to study price transmission across stages of production and final demand. This system is constructed in a manner that maximizes forward flow of production between stages, while minimizing back-flow of production.
Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of …

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is …
2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...
The COVID-19 pandemic, also called the coronavirus pandemic, is a current pandemic of coronavirus disease 2019 (COVID-19). It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The outbreak started in Wuhan, Hubei, China, in December 2019.The World Health Organization (WHO) called it a pandemic on 11 March 2020. The International Committee on …

The rolling process is shown in Fig. 2.1: 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, …
True Polar Wander: Geology vs Bad Science Fiction. It's possible that True Polar Wander, deepened the Cenozoic ice age about 3 Ma (Woodworth & Gordon, 2018).There is even evidence of a couple of TPW episodes of >50° shifts during the Neoproterozoic Era (Maloof et al., 2006).However, there's no evidence that Earth has tipped on its side at any point in the past 600 Ma or so.
Rolling is the main method of metal plastic forming with its products accounting for more than 90% of metal plastic processing. Through rotating rolls, the continuous plastic deformation of the metal leads to a change in size and shape, while at the same time improving the metal structure and material properties.

The base flow provides the spatially variable coefficients of the underlying partial derivative eigenvalue/initial-value problem. Any algorithm for the solution of the latter problems can be influenced by the quality (accuracy) of the underlying base …
A series of flow stress–cumulative strain curves for pure copper processed by MDF with pass strains of 0.4 to various cumulative strains Σε at a strain rate of 3 × 10 −3 s −1 at temperatures of 195 K, 300 K and 473 K,, . The flow curve envelope at 195 K extends to a strain of Σε = 18 (not shown).
The calculation of average material contact pressure to rolls base on mathematical theory of rolling process given by Karman equation was solved by many authors. The solutions reported by authors are used simplifications for solution of Karman equation. The simplifications are based on two cases for approximation of the circular arch: (a) by polygonal curve and (b) by parabola.
