Cold Rolling Mill

Cold Rolling is a continuous high speed deformation process, keeping the temperature below the crystallization point.The material produced after cold rolling can be sold as: Full hard: Cold rolled steel, without annealing and with a low ductility. It requires for use a later stage of annealing or galvanizing.

Cold rolling is a process by which metal is passed through rollers at temperatures below its recrystallization temperatures. The metal is compressed and squeezed, increasing the yield strength and hardness of the metal. Cold rolling of metal strip is a special segment within the metalworking industry.

The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength.

Process by which hot rolled strip or stock is introduced between a set of rotating rollers and then squeezed or compressed to the desired thickness.
