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.

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

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,
Roll stack deflection is an important issue in the determination of profile and flatness of a strip rolled in hot strip mill. A simple roll deflection model has been developed to predict the deflection of the finishing stands of a hot strip mill.
In many hot strip mills the front stands of finishing group are working with rolls made in High Speed Steels. The success in using these rolls is strictly in connection with the mill technology but also with redressing methods applied in the turning shop. The HSS rolls show an impalpable wear and then the evaluation of roll surface
In Hot Strip Mills KELK offers Looper Load Cell Assemblies dimensioned to integrate into existing looper arms. These Assemblies contain special Load Cells as well as additional sensors to measure looper angle and looper acceleration in applications which require the derivation of strip tension for the mill

Jun 01, 1982 According to the present invention, there is provided a deflector roll in a strip mill for measuring the distribution of tension across the width of a strip contacting the roll, the deflector roll being divided into a plurality of sections arranged axially one adjacent to another, these sections being supported against the force imparted to the
A Bridle roll unit can affect the tension in the strip according to the formula T2 = T1eμα, 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 existence of scale during hot rolling between steel and rolling rolls has significant effects on the tribology,1–4) putting it into the roll bite of the No. 1 Mill, and then pulling it from out of the envelope. The rolling speed Deformation Behavior of Oxide Scale in Hot Strip Rolling Hikaru OKADA*
rolling mills with regardsto better strip’ssurface qua lityand for higher productivityof the rolling mills. A compound roll with the outer layer made of high alloyed steel corresponding to the familyof alloysused for cutting tools, which iscalled HSS rolls wasdeveloped and introduced into hot strip millsin Japan in
Analysis of Roll Stack Deflection in a Hot Strip Mill Predictive models are required to provide the bending set point for bending for the flatness control devices at rolling stands of finishing mill of Hot Strip Mill (HSM). A simple model for roll stack deflection at the finishing mill
The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll diameter etc.).
the process control system. I n hot and cold rolling mills 4, the demands on mill profitability, pro-ductivity and product quality are on the rise. At the same time, mill flexi-bility has to match the growing variety of products. Strip quality and mill throughput are influenced by various factors such as mechanical design,
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.
For hot strip mill Edger applications, Xtek developed another special steel grade with superior resistance to the thermal fatigue and firecracking so prevalent with other rolls in this environment. Plate Leveling Rolls round out the Xtek’s roll product offerings with a special heat treatment providing more consistent depth of hardness
plate mill — power meets precision Quality plate is about metallurgical precision high strength and toughness at alloying levels that keep costs down and preserve weldability. It is also about maintaining precise thickness across the full width, as well as consistent flatness to assure fit-up in fabrication.
system was relatively slow and depended upon the roll separating force, the speed of the mill, and the roll finish utilized. But it was effective enough eventually to permit automatic shape control as long as an adequate shapemeter was installed on the deflector rolls to give an accurate indication of strip
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.
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.
And at the time of mill roll changing, Center Looper and Delivery Looper stores the strip to keep intermediate rolls and back-up rolls can be changed while strip is in the mill.
