Carbon Steel reversing 4hi cold rolling mill unit

the Reversible 4hi cold rolling mill has AGC control, pressing adjustment, work Roll's positive and negative bending and other adjustments.

the Reversible 4hi cold rolling mill unit is widely used in cold rolling production of carbon steel, and can also be used for cold rolling blanks of stainless Steel.

1. the purpose and characteristics of the reversible 4hi cold rolling mill unit

1) It is suitable for Rolling materials such as common carbon steel, stainless steel, and special Steel.

2) Two transmission Methods of work roll and back up roll are available: two control methods are Available of normal electric pressing and AGC hydraulic pressing.

3) Can be configured with work roll bending roller device, which can quickly adjust the convexity of the roll, change the output pressure distribution of the roll, and achieve the purpose of controlling the shape.

4) the mill structure Is simple, easy to repair operations and less investment.

5) AGC's control Accuracy is high, especially suitable for the production of high precision cold Rolling bands.

2. the composition of 4 Hi cold rolling Mill unit

this Unit is a 4 Hi cold rolling mill. It includes main motor, reducer, human Character gear seat, universal connection, bracket, working machine seat, motor Pressure device, left, right roll machine, hydraulic station and DC electrical Control, the backup roll material is 9CR2MO. the bearing seat is attached to the roller device for easy change.
