The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.

Working Principle of Rolling The Rolling Process consists of two opposing rollers and a metal squeezing in between them. The basic consideration is that the thickness between the rollers should be less than the Metal's (Ingot) Initial Thickness. This consideration will help metal's forward motion as it passes through the gap between the Rollers.

Working Principle: The cold rolling mills use the motor to drag the reinforcement, and the load-bearing roll and working roll of the cold rolling mill jointly apply the force to the two surfaces of the reinforcement. By changing the gap between the two rolls, the purpose of rolling cold-rolled ribbed bars with different diameters is realized.

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.
