sufficiently lower the steel temperature during finishing rolling (see the schematic layout in Fig. 5). The former two stands of the RSM were designed for high rolling loads of low-temperature rolling (the lowest steel temperature at the mill entry of 750 ℃); the roll diameter for these stands are 246 mm, larger than that of conventional mills

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.

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.
Considers some of the distributed aspects of the control of modern metal rolling mills. Such mills have a range of ever more ambitious targets, for example product quality, yield, metallurgy and throughput. These aims are supported by high levels of mill sophistication, in terms of plant equipment, instrumentation, actuators and control hardware. In spite of this …
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 ...

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.
During hot rolling, steel is deformed at roll bite at temperature ranging typically from 850 to 1150 °C. Under severe cyclic mechanical and thermal loads and in presence of abrasive scale, wear of rolls is inevitable. The paper reviews adverse effect of roll wear on performance of the HSM. Factors responsible for higher wear rate of rolls have ...
