A cold rolling mill is a device that rolls a certain thickness of a plate to a target thickness at a "recrystallization" temperature (including normal temperature). The traditional cold rolling mill is controlled by a torque motor and a DC motor.
Cold rolling mill equipment generally consists of three parts, namely uncoiler, main machine, coiler (reversible rolling mill does not separate coiling and coiling)
The main purpose of the cold rolling mill: The cold rolling mill is used for rolling metal strips such as carbon, special carbon steel, aluminum, copper and zinc. Application: Cold rolling mill is mainly used in steel industry, metallurgical industry and so on.
With the development of power electronics and control technology and the emergence of high-performance vector frequency converters, the application of frequency converters on cold rolling mills has become increasingly widespread.
