1. Two High Rolling Mills It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable. The rolls rotate in opposite directions and are driven by electrical motors.

4. ROLLING MILLS In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

Abstract An analysis of the helical rolling process shows that the change in the axial speed of the roll along the length of the groove of the crossroller mill does not correspond to the required nature of the change in the speed of the deformed billet. The process proceeds under intense axial compression, as a result of which a significant part of the metal being compressed in the contact ...

A rolling mill is a mill that uses compression on a single, double or even triple cylindrical wheel that is rotated along the long axis against another wheel or a plate. The cylindrical wheels are mounted horizontally and only one is run by a motor to move the grains between the two wheels while the other moves slowly as a result of friction.

Pass the heated steel through a rolling mill machine. The machine reduces its thickness and shapes it into the desired form. This process results in increased dimensional accuracy and reduced surface defects. Step 3: Compression. After shaping the material in the rolling mill machine, it then undergoes compression by a series of rollers.
