Jinfutai Iron and Steel——Cold rolled thin steel plate production line

The cold rolling line is mainly used for processing and producing metal products including thin sheets, strips, or those of other shapes. About our cold rolling lines:

Key Specifications and Applications:

It is suitable for the automated dry planishing and production of steel strips, copper strips, aluminum strips, and others.

The strip steel width ranges from 200 to 380 mm, with a billet thickness ranging from 0.2 to 1.2 mm, elongation ≤3%, and a planishing speed of ≤300 m/min.

Process Flow:

Shearing Butt Welding Machine → Entry S-Roll → Entry Anti-crossbreak Roll → Four-Roller Planishing Mill → Exit Anti-crossbreak Roll → Exit S-Roll → Coiler.

Key Components:

S-rolls, anti-crossbreak rolls, and anti-bounce rolls are installed in the front and back end of the equipment, and automatic threading and user-friendly operation are available.

Functions:

Automatic control is implemented over elongation, rolling force, roll gap, and tension during the rolling process.

Strip steel shape, elongation, rolling force, roll gap, tension, current, temperature, and pressure parameters are automatically displayed, and manual shape adjustment is supported during rolling.

Mill roll gaps are adjusted and leveled manually facilitated by hydraulic AGC control.

The fully digital AC variable frequency speed control system ensures automatic control of rolling speed in the unit.
