Apr 12, 2017· Deflector rolls are used as support rolls for the metal sheet passing on it. In cold rolling mills, the wrap angle (contact angle of sheet over the roll) helps in maintaining tension over the sheet.
You'll appreciate X-Roll ® hot strip mills from SMS group as all-round plants for high-quality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of 1.2 millimeters to high-strength pipe steels up to 25.4 millimeters thick, including stainless steel grades.

HDL® Brush Rolls. Osborn HDL® brush rolls are used in cold strip lines. Applications such as washing, degreasing and cleaning of strips, activation of strip surface, polishing and finishing of strip surface as well as scale removal after hot and cold mill processes are most common.
HOT ROLLING During hot rolling, billets are progressively formed into smaller cross sections and emerge as hot rolled bars or coils of rod, flat strip, or special shapes. Some hot rolled product may be shipped directly to customers. COLD FINISHING Cold finishing operations include cold drawing or rolling, turning, and grinding.

Jan 14, 2017· For rolling of hot strip, the slabs are heated initially at 1100 deg C to 1300 deg C. The temperature in the last finishing stand of the hot strip mill varies from 700 deg C to 900 deg C. It is always to be above the upper critical temperature to produce uniform equiaxed ferrite grains.
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 hot-rolled to strip, mills require maximum throughput and availability ...
A Bridle roll unit can affect the tension in the strip according to the formula T2 = T1·eμα, where T1 and T2 are the tensions on either side of the bridle roll, μ is the coefficient of friction between the roll and the strip, and α is the angle of wrap of the strip around the roll in radians.
The cooling of working rolls is an important process in the hot rolling technology. The optimal cooling of rolls should be designed with respect to two aspects. The first is the wearing of a roll where high temperature decreases the durability of the surface layer. The second aspect is a thermal deformation of a roll.
SMS SIEMAG Hot Strip Mills 2 ADAPTING existing hot strip mills to present-day market requirements Owing to their size and high investment volume, hot strip mills have an extremely long life. Almost 40 % of the 140 conven-tional hot strip mills currently in operation all over the world were built between 1960 and 1970. At that time, these mills
process is the amount of friction in strip rolls. The roll friction is considered as one of the complex phenomena in hot strip mill process. In this article, we intend to obtain a mathematical model to calculate friction profile of rollers of Mobarakeh steel company hot strip mill unit. To do this, we need to .

CGL production capacity increase with Fives technologies. 18/11/2018 Steel USA. Steel Dynamics, one of the largest domestic steel producers and metals recyclers in the United States, has contracted Fives to upgrade the continuous galvanizing line №2 (CGL №2) at the Flat Roll Group Columbus Division located in Mississippi, USA.
The extension of the working life of the roll surface is therefore of major interest to the rolling mill. In the hot rolling of the flat sheet, the rolls in the first finishing stands of the hot strip mill experience the most wear with a corresponding reduction in strip surface quality, and thus must be .
A deflector roll for a strip mill is divided axially into sections to be able to measure the distribution of the strip tension across the strip width. To avoid transmitting the measuring signals from movable parts, the sections of the deflector roll are supported by rollers journalled in stationary holders, the force-measuring transducers being built into the holders.
