A 3HI mill stand is essentially needed in hot rolling reversing mills without switching the order of rotation of the rolls. In this type of mill stand, there are three working rolls. The top and bottom roll rotate in the same direction; meanwhile, the centre roll turns in the opposite direction. This is important as the workpiece bar keeps ...
Product description. The 4high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the backup roll is driven, depending on customer requirements. The diameter of the 4high work rolls amounts to approximately 1:4 in relation to the barrel length.
Engineers are mastering methods of rolling − mm strip that was earlier manufactured at cold rolling mills only. Tension in interstand gaps of the continuous train is found to influence ...
The fourhigh roll configuration is used for rolling of plates and for hot rolling and cold rolling of steel strip. It is used both in the nonreversing and reversing rolling mills. Six high mill roll configuration In this type of roll configuration, there are six horizontal rolls, mounted in a single vertical plane. Two rolls (inner) are ...
1. Vertical Mill Stand The updrive type consists of a roll stand, mill spindles, a vertical gear reducer with a pinion stand and a motor. The gear reducer and motor are installed on a concrete frame to protect them from roll cooling water and mill scale.
Fig. (Z>), shows three high rolling mills, having three rolls in the working stands and rotation of their' rolls is nonreversible. Fig. 4High and Cluster mill. Four high mills have four rolls, Fig. (u), arranged in a vertical plane. Two smaller in diameters are working rolls, while larger one are called Backup rolls.

1. Introduction. The production process of hot rolled flat steel products consists of multiple steps. After casting, the steel slabs are reheated and rolled on a roughing mill to get a thickness around 35 final product thickness in the range of mm to 20 mm is then achieved in a tandem hot strip finishing mill [1].Further thickness reductions may follow on a tandem cold rolling mill.
The descaling operation on a Hot Strip Mill (HSM) uses high pressure water jets to remove the thick, hard and brittle oxide scale, in order to avoid oxide embedding into the metal which degrades ...
FourHigh: A fourhigh mill can be used to finish roll thin gauge stock. For narrowwidth ribbon and foil products, 6HI roll inserts are also available. Combination rolling mill: A combination rolling mill is a versatile "twoinone" type of metal rolling mill that can perform 2HI and 4HI rolling operations.

In hot rolling, wear of the work roll takes place mainly because of: (i) abrasion of the roll surface due to contact with the strip, and in a four high mill, due to contact with the backup roll also (ii) fatigue of the surface layers due to the variable nature of mechanical stresses applied by the strip and the backup roll
This plastic kit includes walls, support trusses, soaking pit details and a fourhigh reversing mill stand complete with rolling table, motor and walkway details. The interior of the walls have molded cut lines allowing easy removal of lower side wall sections to reveal the interior, just as on the prototypes.
Backup rolls are the main tool in a fourhigh rolling mill; the rolling forces applied in load cells promote the fatigue of the material due to mechanical contact between backup rolls and work rolls.
