Forging is a process in which material is shaped by the application of localized compressive forces exerted manually or with power hammers, presses or special forging machin The process may be carried out on materials in either hot or cold state When forging is done cold,...
Strain hardening also called work-hardening or cold-working is the process of making a metal harder and stronger through plastic deformation When a metal is plastically deformed, dislocations move and additional dislocations are generated The more dislocations within a material, the more they will interact and become pinned or tangled...
Warm Working It is defined as the mechanical working of metal at a temperature between that of Hot working and Cold Working Ingot is the starting raw metal for all metal working process Molten metal from the furnace is taken and poured into metallic moulds and allowed to cool or solidify The cooled solid metal mass is then taken out of the ....

Jan 14, 2013 0183 32 cold rolling forms hot rolling 6 HOT ROLLING Hot rolling is a metalworking process that occurs above the recrystallization temperature of the materialHot rolled metals generally have little directionality in their mechanical properties and deformation induced residual stress...
In hot working, the temperature at which the working is completed is critical since any extra heat left in the material after working will promote grain growth, leading to poor mechanical properties of material In comparison with cold working, the advantages of hot working are No strain hardening Lesser forces are required for deformation...
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process...
Cold working processes Below the recrystallization temperature if the mechanical work is done on the metals, there will no grain growth but it must be grain this integration elongation, the process is known is cold working process In cold working process greator pressure is required than that required in hot working As the metal is in a ....
work metal limit the amount of forming that can be done, 3 sometimes cold forming-annealing-cold forming cycle should be followed, 4 the work piece is not ductile enough to be cold worked Warm working In this case, forming is performed at temperatures just above room temperature but below the recrystallization temperature...
Annealing is a process by which the property of steel is enhanced to meet the machinability requirements Annealing is a process of heating the steel slightly above the critical temperature of steel ie 723 Degree Centigrade and allowing it to cool down very slowly There are various types of annealing They are as follows full annealing, process annealing, stress relief annealing ....

Jun 03, 2016 0183 32 Today I am going to tell you main difference between hot working and cold working They both are the metal forming process When plastic deformation of metal is carried out at temperature above the recrystallization temperature the process, the process is known as hot working...
Cold working is the process of strengthening metals through plastic deformation This is made possible through the dislocation movements that are produced within a material s crystal structure This is a technique commonly used in non-brittle metals that have remarkably elevated melting points...
Press working may be defined as, a manufacturing process by which various components are made from sheet metal This process is also termed as cold stamping The machine used for press working ,...
