A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
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.
Rolling mill perfonnance 43 this is the case, it means that the resonant frequencies need to be well separated. The group spent a substantial amount of time on this question and reached the following

Jan 08, 2014· For example, in a low quality mill where the product is predominantly rebar, a high average reduction can be used. On the other hand, a special bar quality (SBQ) mill rolling to a tight tolerance, or rolling a mixture of alloy steels, tool steels and high temperature alloys would require a low average reduction.
Calculator for Rolled Length of Roll of Material Calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given.
Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
