Hot rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, it is very important to study roll wear at high temperature, although roll wear study in a real rolling mill is very difficult, especially for a hot rolling mill.

Fig 7: Radial and tangential view at the wear track produced by rollingsliding contact of hot steel (900 o C) against the adamite roll [6]. At the onset of the rolling sequence, grooves are newly dressed and each calibre point has the same roughness. As the sequence of rolled bars continues to pass through the calibre, the geometry of the calibre changes unevenly due to the above differences ...

Gage control in multiple rolling mills is achieved through measurement of strip thickness using xray gage and adjusting the strip tension using feedback control system. Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls get deflected by high rolling forces.

tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.
