Extensive range This market segment covers forged Work Rolls and Intermediate Rolls for use in Wide Cold Strip Mills of 2-high, 4-high, or 6-high types, including reversing Reduction Mills, Tandem Mills, Double Reduction Mills, and Temper/Skin Pass Mills. Our Rolls can be supplied in a number of grades to suit various applications, materials, and rolling conditions.
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.
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.
Abstract. Work rolls made of indefinite chill double-poured (ICDP) iron are commonly used in the finishing trains of hot-strip mills (HSMs). In actual service, spalling, apart from other surface degeneration modes, constitutes a major mechanism of premature roll failures.

May 11, 2005· Work roll changes account for a large proportion of downtime in the operation of hot strip mills, resulting in financial penalties for the mill operators in terms of lost production and roll .
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

Work Rolls for Hot Strip Mills Gerdau Summit offers various roll options to meet the wide range of needs of rolling applications. Rolling mill rolls are made using a casting process, in which the outer layer of the roll (work layer) imparts wear resistance, while the inner layers (core) provide a combination of tenacity and mechanical ...
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 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
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.).
