The Hot Mill rolls slabs weighing up to 30 tons between 30" and 74". Steel slab 8 to 9 inches thick and up to 36 feet long is rolled into strip as thin as 1/16 inches and up to a halfmile in length. Coils are produced with a 30"
The new Hot Strip Millwith 3 Million Tonne per annum (MTPA) capacity is a stateoftheart mill with few parallels in India and will be producingworldclass hot rolled (HR) coils. Incidentally, within two days of the commencement of hot trails of the mill, it has rolled out its first coil successfully
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 .
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. Since close to half of all steel produced is hotrolled to strip, mills require maximum throughput and availability ...
Dec 03, 2015· The primary function of the conventional hot strip mill (HSM) is to reheat the semifinished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling up the lengthened steel sheet for its easy handling and ...
The sheet can whip/hit into the roll surface and mark it. As a result, the following coil produced through the hot strip mill will have these bruises on the head end. If the marks on the work rolls are light, the defect only bruises the next coils surface and eventually wears off the rolls .
ArcelorMittal Dofasco operates a modern 7stand Hot Mill that provides high quality Hot Rolled Steel to our Automotive, Construction, Tubular and Service Centre customers. The mill also supplies down stream operations (Cold Rolling, Galvanizing and the Tin Mill). Our advanced Hot Mill .
Hot Rolled Steel. The hot strip mill is designed to produce consistent surface quality, uniform mechanical properties, and consistent thickness and crown. Walking beam furnaces minimize surface damage during slab reheating. Scale breakers remove heavy furnace scale and provide
Sep 11, 2014· The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by ...

A pair cross type rolling mill has been developed for the requirements to control the shape and crown of hotrolled strips. [1] The upper rolls and lower rolls are skewed in a pair which consists ...
The Hot Strip Mill is capable of producing 2 Million tons of hot rolled coil annually in a width range of 35 in. 53 in. and a gauge range of in. through in. Our 4tank Pickle Line can process 1 million tons of Hot Rolled Coils annually between 29 in. and 56 .
Introducing the influence function into the analysis of roll''s elastic deformation, a design algorithm was proposed for the initial profile of work roll on hot strip mill.
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 halfmile long and includes a walking beam reheat furnace, a twohigh scalebreaker, five fourhigh roughers, a crop shear, six fourhigh finish mills, and two downcoilers.
The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a .
The widest range of hot rolled products, with thickness up to mm, width up to 2050 mm and coil weight up to 36 mt. The widest Hot Strip Mill (HSM) in India, capable of rolling up to 2150 mm. A rare product portfolio, perfect for line pipe applications, with the capability to .

You''ll appreciate XRoll ® hot strip mills from SMS group as allround plants for highquality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of millimeters to highstrength pipe steels up to millimeters thick, including stainless steel grades.
Unprocessed bands are shipped directly off the hotstrip mill and haven''t been trimmed or cropped back to gauge. Additional processing such as temper passing, pickling, edge trimming, and tension leveling are available on site or through a wellqualified external processor.
NOTE: Hotrolling and coldrolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hotrolled or coldrolled. HOTROLLED STEEL. Hotrolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.
Apr 01, 2015· In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
This capability is strengthened with the deployment of our new, billion HotRolling and Processing Facility in Brackenridge, PA, the most powerful hotrolling mill in the world. This facility helps us deliver industryleading 60 in.79 in. wide plate products with unprecedented melttoship lead times and benchmark efficiencies and yields.
Hotrolled steel offers performance, versatility and value. Tata Steel''s line of hotrolled strip steel includes forming and structural grades, heattreatable steels and advanced and highstrength lowalloy steels. All are specially designed for specific and demanding applications.
Jul 16, 2008· The dynamics of shape or profile depends on the several process parameters in a hot strip mill. This research paper presents the prediction of the profile or strip crown generated during rolling in the finishing stands of a hot strip mill with the use of artificial neural network (ANN) by taking into account the operational parameters such as width, thickness, speed, and roll bending, among ...
