Product range includes forged steel work rolls, tension leveling rolls, bridle rolls, furnace rolls, deflector rolls, pinch roll assemblies and roller tables.
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 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 .
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.
In a four-high hot strip mill, the finishing mill of the hot strip mill is equipped with two work-rolls and two back-up rolls and is shown in Fig. 2. During the passage of the strip between the two work rolls, a large amount of roll separating force is developed.

roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the

After exiting the finishing mills, the strip is carried down by a large number of individually-driven rolls through four to 12 banks of low-pressure, high-volume water sprays that cool the red-hot strip to a specified coiling temperature between 400 deg C and 900 deg C and into down coilers.
Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H. Schröder July 2003 K. H.
