In a hot rolling mill, high speed steel, which has a high wear resistance, is used for the rolls, and the high speed steel rolls have an increase in roll life with improvement of the roll performance1,2. however, in the hot rolling mill roll, there is a case which a crack initiates by thermal cycling on.
The roll surface in the roll bite is subjected to high pressure that is greater than 10,000 mpa and further shear stress generated by friction 16 at the rollstrip interface. the premature failure of a work roll increases not only the cost of the rolling but also the down time of the mill, affecting the productivity signicantly.
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 this paper, the vibration characteristics of a 20-high sendzimir mill with localized defect on the working roller is studied. the three-dimensional finite element model of the roll mill is established, including the first intermediate rolls, the working rolls and the strip.
That results in consistently high grinding quality on the roll. thanks to the combination of hydrodynamic and hydrostatic spindle lubrication, herkules achieves a minimal bearing play for both very high and very low revolutions per minute and thus a precise positioning of the wheel under changing load conditions.
