Product Description

High precise 20-roller reversible cold rolling mill /equipment/machine/production line

1. Brief Introduction

This 1450mm 20 Hi Reversible Cold Rolling Mill machine  was designed to roll 1.0~3.0mm plain carbon steel, low alloy steel and  200, 300,400 series stainless steel board into 0.2-1.2mm thick as clients'requirement. The model has flexible rolling process,  and it can adapt to changing raw materials and product specifications in a wide range, The equipment is relatively simple, taking small space for construction, with low investment, and quick returns.

4. Equipment Level

1. Full hydraulic pressure, hydraulic AGC automatic control. It has constant roll gap position control, constant pressure control, roll deviation adjustment, thickness pre control, monitoring function etc.
2. The whole control system adopts the upper computer control management technology, the full digital DC speed control device, the decentralized PLC unit process control and the remote communication networking technology. Through the two stage network, the rolling mill power supply, the AC and DC main motor control, the PLC system, the remote I/0 system, the AGC PLC system, the human-machine interface (HMI) are integrated into one. Unified design of the interface relationship of each system, thus forming the modern automatic control system of the rolling mill.
3. The main operation console is equipped with man-machine interface, which completes the rolling mill status screen display (winding tension value, current value, speed value and other main process parameters) and manual adjustment, rolling process parameter setting, fault alarm and printing report.
4. The main components and hydraulic pumps of the low-pressure hydraulic system adopt domestic high-quality products; the high-pressure AGC hydraulic system and key seals adopt imported products.
