PHYSICAL METALLURGY OF A HSS MATERIAL FOR HOT ROLLING MILL ROLLS Jacqueline LECOMTE-BECKERS 1 Jerome TCHOUFANG TCHUINDJANG 1 Eric PIRARD 2 Jean-Pierre BREYER 3 ABSTRACT High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills.
Typical upgrades to hot mill stands include the addition of roll bending for profile and shape control as well as the installation of hydraulic roll force systems for automatic gauge control. Customers are also looking to see production improvements by eliminating mill down time through shorter roll changes.
Usually these mills are provided with no twist rolling in the blocks and controlled cooling of the rods after rolling. Plate mills – These are flat mills to produce heavy plates. Hot strip mill – These are also flat mills and rolls hot strips from slabs. Cold strip mills – These mills rolls cold strips from hot .
Work Roll Shift Mill. Primetals Technologies have been a pioneer in the field ever since we developed the world's first Work Roll Shift Mill and have enhanced this technology based on our extensive experience in steel industry. Primetals Technologies utilizes the Work Roll Shifting at hot strip rolling field for different two purposes:
in multi-roll cold rolling mills. In close partnership with the customer, we therefore continually design, test and develop to production-ready status new bearings optimally suited to this application. The quality of FAG and INA back-up rollers is ensured by means of high precision machining and sophisticated measurement methods.
The effects of hot rolling on the surface roughness and oxide layers such as reduction, roll speed, and entry temperature, were investigated to identify any significant parameters. Hot rolling experiments were carried out on a HILLE-100 experimental rolling mill. Five .
WORLD CLASS ROLLS OF THE HIGHEST QUALITY FOR OVER 100 YEARS. The WHEMCO companies in Pennsylvania and Ohio, USA manufacture a full range of mill rolls – spun cast iron, cast steel and forged steel. Each of our roll manufacturing facilities has the expertise, equipment and experience to meet the most demanding rolling mill applications.
Often, a large variation in roll face temperature will not allow the product to release properly from a roll. These locations are hot spots. They result from blockage in the cooling passages of a roll. An internal acid flush or removing the outer shell and cleaning the internal passages will .

A simple roll deflection model has been developed to predict the deflection of the finishing stands of a hot strip mill. The roll deflection model indicates the effect of width for deflection as well as the effect of bending. The effect of work roll bending and the roll width has been studied by this model.

maintenance, roll covers and replacement rolls are also available. Inspections minimize unexpected downtime Regular roll inspections are the key to avoiding unexpected failures. Valmet's experts compare inspection results with the original roll specifications, then, based on that comparison, provide the mill with maintenance recommendations.
Work roll thermal expansion (crown) plays an important role in controlling strip profile and flatness of the strips. This can be done with a perfect and controllable cooling system which also takes care of the work roll against damage induced by fire cracking.
In summary, in most mills the primary surface to target is the work roll. Which side of the mill should one be cooling? The determination of which side of the mill to cool depends upon the overall mill design and cooling strategy. In the typical hot mill, cooling is .

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,
The cooling of work rolls is an important process in the hot rolling technology and cannot be taken as a marginal issue. The Heat Transfer and Fluid Flow Laboratory designs cooling of rolls to reach their long working life while rolled product is still well heat treated.
