TX has experience in developing and manufacturing roll forming machines for more than 30 years, so far the types of profiles that are produced by TX roll formers are more than 7,000. Customized solution is provided based on the individual need of each customer. Now let’s use our professional knowledge to introduce steel cold roll forming and hot roll forming
What is steel cold roll forming?
Cold rolling is a process in which a metal is passed through a roll at a temperature below its recrystallization temperature. The metal is compressed and squeezed, increasing its yield strength and hardness. Cold rolling of metal strips is a special link in the metal processing industry.
In making more precise shapes, the process involves decomposition; Semi-finishing; Sizing; Semi-rough machining; Rough machining; Finish machining.
Advantages of steel cold roll forming
Cold-rolled steel generally results in better, cleaner surfaces and smaller tolerances. It can also produce a smoother surface that feels greasy to the touch. Other advantages include:
Can be used for precision applications;
Harder and stronger than hot-rolled steel;
Improve the hardness, tensile resistance and resistance to work hardening deformation;
Anesthetic finish with a wider range of surface finishes.
Application of steel cold roll forming
Cold rolled steel is used in applications where tolerances, surface conditions, concentricity and straightness are the influencing factors. It also provides a more aesthetic and visually appealing surface. Other applications include:
Aerospace structural parts;
What is steel hot roll forming?
Hot rolling is the process used to manufacture hot rolled steel, which involves rolling steel at high temperatures (usually in excess of 1700°F). These high temperatures are higher than the recrystallization temperature of the steel, making it easy to shape, shape and manufacture the steel into larger sizes. As it cools, hot-rolled steel tends to shrink unevenly, with less control over the size and shape of the finished product than cold-rolled steel.
Characteristics of steel hot roll forming
Hot-rolled steel often has a scaly surface that can be removed by pickling, grinding or sandblasting. The steel is essentially normalized, which means there are no internal stresses that could be caused by hardening or work-hardening processes because it can be cooled at room temperature.
Hot-rolled steel is often cheaper than cold-rolled steel because it is manufactured without any delay and does not need to be reheated as cold-rolled steel does. It’s also basically normalized because it can be cooled at room temperature; This means there is no internal stress due to quenching or work-hardening processes.
Application of steel hot roll forming
Hot-rolled steel is often cheaper than cold-rolled steel because it is manufactured without any delay and does not need to be reheated as cold-rolled steel does. It can be used in applications where precise shapes and tolerances are not required, for example:
Structural components (rail, I-beam, sheet metal)
