Fundamental concept of metal rolling - mtixtl
Fundamental concept of metal rolling 1) The arc of contact between the rolls and the metal is a part of a circle. 2) The coefficient of friction , µµµµ, is constant in theory, but in reality µµµµvaries along the arc of contact. 3) The metal is considered to deform plastically during rolling. 4) The volume of metal is constant before andsp.info

Rolling of Metals:Process and Principles (With 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.sp.info

Rolling Process:Working, Application, Defects, Type
Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One is Hot rolled and another is Cold Rolled.sp.info METAL FORMINGRolling is the most commonly used and the most efficient type of metal forming, which consists in deformation of metal by means of rotating rolls (Fig. 1.1, a, b, c); 75-80% of the total quantity of smelted metal is being processed by rolling. a b c d e f g h Fig. 1.1.

Material is passed between cast or forged steel rolls, which compress it and drag it forward. Rolling is an economical method of deformation if metal is required in long lengths of uniform cross section.
