Description

Technical Field

[0001] This invention belongs to the field of pinch roll installation technology, specifically relating to an installation and adjustment device and method for a pickling exit pinch roll. Background Technology

[0002] The pickling and rolling mill is used to complete the continuous pickling and rolling process of hot-rolled steel coils. During the continuous pickling and rolling process, the pinch rolls are important components. Long-term use will cause wear on the pinch roll surface or deviation in the angle between the upper and lower rolls, resulting in strip quality defects. It is necessary to replace the pinch rolls or adjust their angle from time to time.

[0003] Therefore, there is a need for an installation and adjustment device and method for the pickling exit pinch roll. Summary of the Invention

[0004] The purpose of this invention is to provide an installation and adjustment device and method for pickling exit pinch rolls.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an installation and adjustment device for pickling exit pinch rolls, including a fixed base, an auxiliary support at the relative position of the fixed base, a roll seat frame at the top of the fixed base and the auxiliary support, a push roll bracket at the first end of the roll seat frame, a drive mechanism at the second end of the roll seat frame, and a transmission screw between the push roll bracket and the drive mechanism.

[0006] A method for installing and adjusting the pickling exit pinch roll, characterized by comprising the following steps:

[0007] 1) Set the pinch roll gap opening value to 92mm;

[0008] 2) Clean the lower roll surface of the pickling exit pinch rolls and remove the anti-rust oil from the lower roll surface;

[0009] 3) Place the roller seat frame on the auxiliary support base, and bolt the push roller bracket to the clamping roller lower roller connecting plate;

[0010] 4) Remove the anti-detachment fixing plate of the pinch roller;

[0011] 5) By rotating the transmission screw through the drive mechanism, the pusher roller bracket pushes the lower roll of the mill exit pinch roll into the mill exit pinch roll frame;

[0012] 6) Clean the surface of the pickling exit pinch rolls and remove the anti-rust oil from the surface of the rolls;

[0013] 7) Adjust the height of the fixed base to the position of the upper roller;

[0014] 8) Place the push roller bracket on the auxiliary support, place the auxiliary support on the auxiliary support base, and bolt the push roller bracket to the clamping roller upper roller connecting plate.

[0015] 9) By rotating the transmission screw through the drive mechanism, the pusher roller bracket pushes the upper roller of the mill exit pinch roll into the mill exit pinch roll frame;

[0016] 10) Reinstall the clamping roller anti-detachment fixing plate;

[0017] 11) Check the levelness of the pinch roller: Place the level in the middle of the upper roller surface and observe the changes in the level. The levelness should reach 0.02mm / m. During the test, rotate the roller body at 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315° respectively to check the levelness of the roller body.

[0018] 12) After setting the pinch roll gap opening value to 30mm, calibrate the pinch roll;

[0019] 13) After calibration, the gap of the pinch rolls at the pickling exit is checked with a feeler gauge and the gap is compensated. Use a feeler gauge to check the gap on the drive side and the operating side of the pinch rolls. If the feeler gauge measurement result is within the range of 0.2-0.3 and the deviation on both sides is less than 0.05, the pinch roll calibration is successful. If it exceeds the range of 0.2-0.3, adjust the gap closing value to ensure that the feeler gauge measurement result is within the range.

[0020] The present invention has the following beneficial effects:

[0021] 1) The special installation and adjustment device for pickling exit pinch rolls of the present invention can install the pinch rolls to the accurate position and can quickly replace the pinch rolls.

[0022] 2) A quick installation method for the pickling exit pinch rolls, using a special installation and adjustment device for the pinch rolls, saves manual labor;

[0023] 3) Methods for checking the levelness of the pinch rollers;

[0024] 4) Check the gap between the pinch rolls and adjust the pinch roll gap compensation. Attached Figure Description

[0030] A method for installing and adjusting pickling exit pinch rolls includes the following steps:

[0031] 1) Open XHMI, set the pinch roll gap opening reference value Ref.Gap:open to 92mm (maximum value), and click Confirm Input and Save Config to save;

[0032] 2) Clean the surface of the pickling exit pinch rolls and remove the anti-rust oil from the roll surface;

[0033] 3) Place the fixed base 1 on the fixed ground; place the roller frame 2 on the auxiliary support base 11;

[0034] 4) Connect the auxiliary pusher roller bracket 7 of the pinch roller to the connecting plate 8 of the lower pinch roller with bolts;

[0035] 5) Remove the anti-detachment fixing plate 10 of the pinch roller;

[0036] 6) The drive mechanism 4 rotates the transmission screw 5, and the auxiliary pusher roller bracket 7 pushes the lower roll of the mill exit pinch roll into the mill exit pinch roll frame.

[0037] 7) Clean the surface of the pickling exit pinch rolls and remove the anti-rust oil from the roll surface;
