Thermal-fatigue resistant work rolls for hot rolling mills
Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The pre-conditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physical …

Looper and tension control in hot rolling mills: A survey
The role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness 0.8–20 mm. Fig. 1 shows a typical layout of a hot strip mill. Slabs are heated up to around 1200 °C in reheating furnaces and then rolled on two reversing roughing mills which reduce the thickness of bars to ...
