ppt on hot angle rolling mill mantelzorgleiderdorp . ... Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening.
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.

Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process. Plastic deformation: Stresses beyond yield strength of the workpiece material is required.

Rolling Processes Almustansiriya University. In cold rolling the value is around 01 in warm working a typical value is around 02 and in hot rolling m is around 04 hot rolling is often characterized by a condition called sticking in which the hot work surface adheres to the rolls over the contact arc this condition often occurs in the rolling of steels and hightemperature alloys
Hot rolled products are made by a hot rolling process. In that process, the process is done at a very high temperature like over 1,700 Degree Fahrenheit. For most of the metals, this temperature is re-crystallization temperature.
