Cold Rolled Steel Sheet Manufacturing Process

Cold rolling causes steel to become hard and brittle.

Cold rolled steel sheet manufacturing process.

Choose from our selection of cold rolled steel including low carbon steel sheets and bars low carbon steel rods and discs and more. As you might suspect the manufacturing process behind cold rolled steel is a bit different. Coils can achieve homogeneous qualities and higher production rate due to higher heat transfer. As an example a hot rolled steel product may have a yield strength of 235 mpa.

In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. It is the first plant in india to use the corex technology for hot metal production.

Cold formed steel cfs is the common term for steel products shaped by cold working processes carried out near room temperature such as rolling pressing stamping bending etc. The vijayanagar plant of jsw steel is the first integrated steel plant to reach 10 mtpa capacity at a single location in india. Cold formed steel especially in the form of thin. The rolls induce plastic deformation.

Tcrss employs 100 hydrogen atmosphere annealing facilities. Stock bars and sheets of cold rolled steel crs are commonly used in all areas of manufacturing the terms are opposed to hot formed steel and hot rolled steel. Despite the name this process refers to steel that is pressed with the pressure of a roller at room temperature. Cold rolling is a process that occurs after hot rolling in order to reduce the thickness increase the yield and tensile strength and pliability of metal.

Hot rolling is a mill process which involves rolling the steel at a high temperature typically at a temperature over 1700 f which is above the steel s recrystallization temperature. Compared to hot rolled steel cold rolled steel has a nearly 20 increase in strength through the use of strain hardening. The amount of strain introd. 1 2 roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal typically steel into products such as structural steel i.

In stock and ready to ship. Widest cold rolling mill for automotive steel in india. In terms of usage hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes.
