HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production.
and process automation systems for hot-strip mills are the reduction of strip-width deviations and the avoidance of below-minimum widths after the finish-ing mill, which is why Primetals Technologies has devel-oped model-based strip-width control. Recognizing that tension can be used to manipulate the strip width in the
Nov 06, 2016· Hot rolling process of flat products is a complex process involving plastic deformation of steel, multi-mode heat transfer, microstructure evolution and elastic deformation of rolls and strips. Computer simulation of this process is essential for design modifications of mill hardware and optimization of process parameters to achieve desired product quality with .
Infrared sensors measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel's temperature. Sensors can be used to detect the presence of hot metal and accurately time the roll stand operation. Pyrometers can be used to measure the roll temperature as water cools the roll during the quenching process.
At the 80" hot strip mill alone, equipment checks are being performed on 7,500 points every week. "Utilizing the MTA and RCM methods with our skilled craft personnel, operators, supervisors and engineers to detect and address issues before failure is a high priority for us," said Brian Warnock, division manager, 80" hot strip mill.
Straight after that, the CSP ® mill rolls them to final strip thickness. If you want to grow with the market, CSP ® is the perfect solution for you. Starting with a single-strand CSP ® plant, you can cost-effectively produce around 1.5 million tons hot strip per year. Later, simply add a second casting strand to double your capacity to more ...
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Dec 28, 2017· The market of rebar and wire rod is going to be saturated in few years, the spring of hot rolled coil, cold rolled coil, galvanized coil, color coated coil are coming. If you need, please contact ...
Hot Sheet and Plate Rolling Fundamentals — Practical Training Seminar. About the Program. This seminar provides a comprehensive overview of hot rolling steel strip and plate.

SMS DEMAG Hot Strip Mills 10 The drum-type shear installed between the roughing and finishing mills of a hot strip mill crops the trans-fer bar at its head and tail. In special applications, the drum-type shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drum-type shears built so far,
Hot Strip Mill. The Hot Strip Mill is where CSI's rolling operations begin, as steel slab is reheated and rolled to hot rolled coil. With an annual capacity of more than two million tons, the rolling mill is more than a half-mile long and includes a walking beam reheat furnace, a two-high scalebreaker, five four-high roughers, a crop shear, six four-high finish mills, and two downcoilers.
The process guarantees high resistance and durability characteristics. About 75% of hydrogen was needed in the original Sendzimir process but all the newer nonoxidizing methods of degreasing require only 7–15%. The rolling of hot steel slabs using a Sendzimir mill requires a much smaller operational area than a continuous hot strip mill. This ...
The process utilizes coiling drums in a coiling furnace to maintain the strip temperature from head to tail ends of the strip as the strip passes back and forth between the rolls of the stand until reaching final size, often referred to as gauge.

"Our hot-strip mill at that time was the bottleneck," he says. "Most. ... Fahrenheit, a process that accounts for a third of the hot-strip mill's. operating costs, Babcoke says. "If you've got a ...
1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.
The strip mill was a major innovation in steelmaking, with the first being erected at Ashland, Kentucky in 1923. This provided a continuous process, cutting out the need to pass the plates over the rolls and to double them, as in a pack mill.At the end the strip was cut with a guillotine shear or rolled into a coil. Early (hot rolling) strip mills did not produce strip suitable for tinplate ...

Dec 22, 2013· Main Features of a modern Hot Strip Mill. The objective of a hot strip mill (HSM) is to reheat and roll thick slabs into thin strip with a wide range of thickness. Because of its huge size and large investment a hot strip mill need to have a life time of several decades.
Apr 29, 2016· 3D animation - Highest performance for new and existing steel mills
Attributes imparted to the strip by the hot rolled strip mill include surface quality, thickness, width, and flatness control as well as strip profile. Rolling of steel slabs in hot strip mill consists of several sub-processes and at the end of them the final product 'hot rolled coil' is produced.
