[0066] Working process:

[0067] Step 1: After the rolling mill stops, the upper roller assembly 4 is lifted by the upper roller vertical displacement assembly 8 (the ball screw in the vertical displacement screw pair 83 is driven by the vertical displacement drive motor 82 (servo motor) to rotate, and the upper roller assembly 4 is lifted along the connecting plate 84 (slant plate)).

[0068] Step 2: After the upper roller assembly 4 is raised to a certain height, the upper roller in the upper roller assembly 4 is moved to just above the lower roller in the lower roller assembly 5 under the action of the upper roller left and right displacement assembly 7 (the ball screw in the left and right displacement screw pair 73 is driven to rotate by the left and right displacement drive motor 72 (servo motor), so that the upper roller assembly 4 is raised along the left and right displacement guide rail assembly 75);

[0069] Step 3: Manually place the upper roller support fixture 10 onto the lower roller in the lower roller assembly 5;

[0070] Step 4: The upper roller in the upper roller assembly 4 is simultaneously moved onto the upper roller support fixture 10 by the upper roller assembly up-and-down displacement assembly 8 and the upper roller left-and-right displacement assembly 7;

[0071] Step 5: The upper roller in the upper roller assembly 4 is disconnected from the upper roller left and right power assemblies 7 under the control of the connecting plate 74;

[0072] Step 6: The upper and lower roller assemblies 4 and 5 are moved to the roller changing station (the portion of the lower roller left-right displacement assembly 6 extending out of the bracket 3) under the action of the lower roller left-right displacement assembly 6 (the roller changing drive motor 62 (servo motor) drives the ball screw in the roller changing screw pair 63 to rotate, and the upper roller assembly 4 is raised along the direction of the lower roller left-right displacement guide rail assembly 65);

[0073] Step 7: Manually replace the upper and lower roller assemblies 4 and 5 with new ones using tools such as overhead cranes;

[0074] Step 8: The upper and lower roller assemblies 4 and 5 are moved to the working position under the action of the lower roller left and right displacement assembly 6. The synchronous transmission assembly 9 is slowly rotated under the action of the active motor 12. The spline automatically aligns and docks and stops rotating after completion.

[0075] Step 9: The upper roller in the upper roller assembly 4 is attracted to the upper roller left-right displacement assembly 7 under the control of the connecting plate 74;

[0076] Step 10: After the upper roller assembly 4 is raised to a certain height, the upper roller in the upper roller assembly 4 is moved to just above the lower roller in the lower roller assembly 5 by the upper roller left and right displacement assembly 7 (which drives the ball screw in the upper and lower displacement screw pair 83 to rotate via the upper and lower displacement drive motor 82 (servo motor), thereby raising the upper roller assembly 4 along the direction of the connecting plate 84 (slant plate)).

[0077] Step 11: Manually remove the upper roller support fixture 10;
