Product Description

20 Hi Stainless Steel cold rolling mill Machine

It is used to roll the material  difficult for deformation such as stainless steel, silicon steel and alloy steel. It has the maximum tension of 40T, the maximum rolling force of 1000 tons and the highest speed of 600m/min. 

Function and Features:

 The stepped roll configuration allows the working rolls to have small diameters and ensures the horizontal rigidity of working rolls. The integrated mill housing design enable the mill to provide sufficient rigidity and spilt design of upper and lower roll boxes ensures large roll gap, allows easy strip feeding and can effectively protect rolls. Meanwhile, the mill is provided with various profile control ways such as setting of backing bearing eccentricity, radian grinding of two intermediate rolls, twitching of one intermediate roll, crown adjustment of A/D supporting roll and injection adjustment of rolling lubricant, thus ensuring good rolling profile.

 

The electric drive system adopts Siemens S7-400 PLC as the main controller and AGC system is controlled by Siemens S7-416+FM458. Key elements, such as MOOG servo valve and SONY magnetic scale, are imported products.

 
 

This 1450mm 20 Hi Reversible Cold Rolling Mill 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.
