While cold hardening promotes greater strength and hardness as well as lower plasticity and viscosity these properties may differ along the cross section of the coil Therefore once discharged from the rolling mill most merchant coldrolled coils go through heat treatment ie annealing in belltype furnaces or on continuous lines
The Cold Rolling Mills are used for reducing the thickness of sheet strip coils of various metals to the desired thickness and to improve various properties like surface finish strength thickness tolerances and achieving required hardness like full hard half hard quarter hard etc Normally these mills are made in 4Hi 2Hi and 6Hi configurations
