the complete technology book on hot rolling of steel
the basic use of hot rolling mills is to shape up the larger pieces of billets and slabs into narrow and desired forms. these metal pieces are heated over their re crystallization temperature and are then moved between the rollers so as to form thinner cross sections.what is hot rolling? corrosionpedia explains hot rolling. scale is produced when the hot surface is oxidized by air. this mill scale can reduce corrosion if steel is exposed to air over short periods however the corrosion increases if exposed for long periods. large amounts of mill scale also cause severe pitting corrosion if the surface is in contact with water.rolling processes rolling processes 5-1 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 5-1 . fig. 5-1 most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.

roll pass designing in continuous bar mills
roll pass designing in continuous bar mills. say that the exit bar from stand 1 has cross sectional area = 3467 sq mm and the finished round has cross-sectional area = 113 sq mm hot bar dimensions . if the finished stand delivers at a speed of 12 mps then stand 1 must 'run' at 0.39 mps: 0.3 x 3467 = 12 x 113.
