HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
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.).
Abstract. Work rolls made of indefinite chill doublepoured (ICDP) iron are commonly used in the finishing trains of hotstrip mills (HSMs). In actual service, spalling, apart from other surface degeneration modes, constitutes a major mechanism of premature roll failures.

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 Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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.

Thermal crown development in hot strip mill work rolls and the role of spray cooling Ye, Xing 1990
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.
The modern hot strip mill is furnished with a tremendous amount of equipment from the reheat furnaces all the way down to the coiling equipment. Fortunately for both our ferrous and nonferrous customers alike Butech Bliss can provide equipment and technical services for nearly every element of the hot strip mill.
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 ...
