Application
The1450mm Reversible stainless steel Cold rolling mill Machine can be used as a roughing mill before the twenty-roll mill. Therefore, the mill has a faster development and a wider range of applications. It can be used for rolling stainless steel, carbon steel, silicon steel, alloy steel( copper or aluminium) and cold-rolled hard-to-deform steel, as well as thin strips and foils for non-ferrous metals.
Features
1.The 1450mm reversible stainless steel cold rolling mill machine is a kind of small diameter working roll and a unique cold rolling mill. It is mostly used in stainless steel production.
2.It is a multi-roll mill that adds side support rolls to the work rolls on the basis of a four-roll mill driven by backup roll.
3.The machine has a maximum speed of 600m/min, which is a non-traditional type of multi-roll cold rolling mill that has appeared in modern times.
4.The output of the eight -high rolling mill can meet the requirements of strength and rigidity required for rolling.
5. It can overcome the lateral bending of the work roll, and has the advantages of simple structure, convenient adjustment, good working stability, reversible rolling and increased reduction.
6. Reduce the number of passes, simplify the cold rolling process(ie reduce the number of intermediate annealing), and improve the quality of production.
It can roll picked stainless steel coils with the thickness of 1.5~3.5mm into high precision cold rolled coils with the thickness of 0.3~1.0mm through several times of rolling. It adopts single-stand stainless steel reversible cold rolling mill, The large tension coiler and thickness gauge etc, which can realize large tension rolling and guarantee high-speed and stable production with specified thinness.

4. Equipment Level
1) The main rolling mill and coiler drive system adopts Siemens 6RA80 full digital DC speed regulation, thyristor power supply and unit PLC control.
2) The basic automation system of the unit is composed of Siemens S7-400 series PLC as the main controller, which is combined with the corresponding remote I/O (ET-200M) to control the operation of the rolling line and auxiliary equipment.
3) The AGC is an automated thickness control system with FM458 function modules. Full hydraulic pressure. It has constant roll gap control, constant rolling force control, adjustment control, automatic pre-pressure control, thickness pre-control AGC, thickness monitoring AGC, tension / speed AGC, acceleration and deceleration AGC compensation control, roll eccentricity compensation and so on, as well as rolling process database, data display and operation control, product quality tracking function, high speed rolling Process management functions such as automatic data recording, automatic report generation, fault alarm and recording.
4) The upper and lower support rollers are separately driven to reduce the consistency of the roller diameter.
5) The rolling mill electrical system has safety protection measures such as overload protection, broken belt protection and emergency stop; the unit has automatic deceleration with tail, accurate parking and multi-point parking function; the coiler has lap number memory, belt length calculation, and accurate support roller shaft GPS.
6) The unit has functions of presetting process parameters, detecting process parameters and key parameters of equipment, displaying, alarming and storing records.
7) 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.
8) The gear adopts five grade precision 20CrMnMo alloy steel carburized quenching gear and oil injection cycle lubrication.
9) Low-voltage hydraulic system components are well-known products produced by domestically introduced technologies; key components of high-pressure AGC systems use imported products.
NOTE: We can customize the cold rolling mill according to our customers' requirements.
