If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.

Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are frequently categorized into plain carbon, alloy, high strength alloy, dual phase, electrical and stainless steels.
The 2+4 EVO reducing and sizing mill uses a patented pass design. A reducing group with 2-Roll stands with high reduction is followed by a sizing group with 4-Roll stands with low reduction. While the 2-Roll high reduction guarantees the desired metallurgical structure, the 4-Roll low reduction provides excellent surface finish and size tolerance.

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 metal rolled.

This book does not focus on these specific rolling mill manufacturers and their various methods of manufacturing and patentability. My intent in this book is to show the modern rolling techniques that are employed today and how technology played a tremendous role in greater safety and improved production in the steel making process.
The rolling process was conducted for two temperatures: 300 and 400 °C. After each pass, the samples were reheated to the rolling temperature. The rolling speed was 0.2 m/s. A laboratory two-high rolling mill with a nominal diameter of working rolls of 150 mm was used for the experimental tests . After each pass, templets were collected to ...
As a process for producing seamless tubes, the tandem skew rolling (TSR) process was proposed. In order to study deformation characteristics and mechanism on tubes obtained by the TSR process, a numerical simulation of the process was analyzed using Deform-3D software. Simulation results demonstrated the distribution of stress, strain, velocity, and …
In accordance with data recorded during actual rolling, the following were taken for simulation: a rolling speed of 6.5 m/s, a roll of 375 mm in diameter, the friction coefficient of 0.4 [5], the ...

ABSTRACT Hot rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, is very important to study roll wear at high temperature, although roll wear study in a re rolling mill is very difficult, especially for a hot rolling mill.
