4.Equipment Level
The more prominent technical characteristics are as follows:
1) DC drive, full digital DC speed control system (using Siemens 6RA80 control system).
2) Full hydraulic AGC reduction control system. (Pressure hydraulic cylinder, AGC control system, hydraulic station, thickness gauge, etc. have constant roll gap position control and constant pressure control and tilt automatic adjustment control function.)
3) The main motor drives the upper and lower work rolls through a combined reducer and universal joint shaft; the backup roll uses four rows of short cylindrical roller bearings, and the work rolls use four rows of short cylindrical roller bearings. The work roll, intermediate roll and backup roll bearings are lubricated with oil and gas.
4) Through the work roll hydraulic bending roll, the six roll intermediate roll twitch, and the roll cooling, it is ensured that the steel strip with high lateral precision and good plate shape is rolled out.
5) Roll segment cooling control, flow control.
6) Work roll positive bending control.
7) The six-roller intermediate roller is traversed to the setting and positive bending roller control.
8) Zero the rolling line pressure.
9) The main gear unit and the gear and pinion of the coiler are made of hardened tooth surfaces. The thin oil circulating cooling lubricates the tooth surfaces and bearings.
10) The work roll and middle roll change roll change, and the support roll hydraulic cylinder is pushed out and pulled in and replaced.
NOTE: We can customize the machines according to our customers' special requirements!
