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. We manufacture both cast and forged rolls for the most flat hot and cold rolling applications.


A metallurgical investigation of failed samples of hot-strip mill work-rolls used in an integrated steel plant was made to determine the influence of microstructural characteristics on failure susceptibility and roll life. The samples investigated pertained to prematurely failed indefinite chill double-poured (ICDP) iron work-rolls, which exhibited varying roll lives under similar mill ...


Thermal crown development in hot strip mill work rolls and the role of spray cooling: Creator: Ye, Xing: Publisher: University of British Columbia: Date Issued: 1990: Description: The objective of this investigation was to determine the influence of work roll cooling on roll thermal behavior.

Simulation of thermal fatigue in hot strip mill work rolls . By R. D. Mercado-Solis and J. H. Beynon. Cite . BibTex; Full citation Abstract. The surface deterioration of work rolls constitutes a significant constraint on the operation of hot mills, as the duration of rolling campaigns are greatly restricted by the surface condition of the rolls ...


Hot Strip Mill Vertical Roll . Usage:this roll is used for hot strip mill as the vertical roll . Roll diameter:max can be 1600mm . Service:besides the production,we also offer the roll ring installation service as the requirement from customer in our company.


An alloy steel containing tungsten (W) and with a hardness of 40 – 50 deg Shore is very resistant to fire cracking and is sometimes used for roughing rolls in hot strip mills. Cast alloy steel base rolls are made also with the analysis ranging C – 0.9 % to 2.5 %, Si – 0.5 % to 1.0 %, Mn – 0.4 % to 0.6 %, Ni – 0.25 % to 1.0 %, and Cr ...

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 service life of rolls. The hot strip mill referred here consists of two stands in a roughing mill ...


Thermal fatigue simulation of cracking related to caster rolls, hot strip mill work rolls and die casting tooling were proposed in e.g. Revel et al., 2000, Srivastava et al., 2004, Mercado-Solis ...


The objective of this investigation was to determine the influence of work roll cooling on roll thermal behavior. The investigation has been conducted utilizing a previously developed computer model [1]. Three industrial operations were evaluated and features of an optimum configuration have been identified. The magnitude of the thermal zone near the roll surface within which the cyclic ...

In the hot rolling of the flat sheet, the rolls in the first finishing stands of the hot strip mill experience the most wear with a corresponding reduction in strip surface quality, and thus must be taken out of service and reground the most often.


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.
