AI Technical Summary
In the existing technology, the side guide plate of the hot roll mill does not open by a fixed amount after clamping and centering, which cannot adapt to the changes in the thickness of the billet in each pass, resulting in problems such as workpiece deviation, wear and impact.
Based on the rolling passes and workpiece parameters of the hot rolling mill, the position and opening value of the side guide plates are dynamically adjusted to ensure that the side guide plates adapt to changes in workpiece thickness and width in each pass, thereby improving the shape control capability and avoiding wear and impact.
By dynamically adjusting the position and opening of the side guide plates, the ability to control the shape of the rolled piece is improved, the wear of the side guide plates and the impact on the rolled piece are reduced, and the accuracy and stability of the equipment are enhanced.

[0002] The side guide plate is an auxiliary equipment of the rolling mill, and its main function is to center the rolled piece and prevent the guide from deviating, and it plays an important role in plate shape control. In the related art, the rolling mill adopts single rack reciprocating rolling. The first step of the side guide plate is clamping and centering, and the second step is to open a certain opening degree according to the set value and keep the position to prevent the guide from deviating.

In addition, in the scheme, the opening value of the side guide plate located at the inlet side when clamping and centering is determined according to the rolling width, so as to ensure that the side guide plate can stably clamp and center the rolled piece.

The opening value of the second side guide plate is determined to be L+400mm based on the current workpiece width. Wherein, h is the thickness of the rolled piece, and L is the width of the rolled piece.
5. The method for controlling the side guide plate of a hot-rolled coil mill according to claim 4, characterized in that, The step of determining the opening value of the side guide plate based on the position of the side guide plate and the parameters of the rolled piece further includes: The position of the first side guide plate is determined as the exit side, and the position of the second side guide plate is determined as the inlet side. The opening value of the first side guide plate after centering is determined based on the current pre-rolling thickness. If the current pre-rolling thickness is h < 10mm, the opening value of the second side guide plate after centering is determined to be 40mm. If the current pre-rolling thickness is 10mm≤h<30mm, the opening value of the second side guide plate after centering is determined to be 60mm. If the current pre-rolling thickness is h≥30mm, the opening value of the second side guide plate after centering is determined to be 80mm. The position of the first side guide plate is determined to be the exit side and the position of the first side guide plate is determined to be the inlet side. The opening value of the second side guide plate is determined to be L+400mm based on the current workpiece width.
6. The method for controlling the side guide plate of a hot-rolled coil mill according to claim 5, characterized in that, The step of determining the opening value of the side guide plate based on the position of the side guide plate and the parameters of the rolled piece further includes: The position of the first side guide plate is determined as the inlet side, and the position of the second side guide plate is determined as the outlet side. The opening value of the first side guide plate when clamping and centering is determined according to the current width of the rolled piece: L. The position of the first side guide plate is determined to be the exit side, and the position of the second side guide plate is determined to be the inlet side. The opening value of the second side guide plate when clamping and centering is determined according to the current width of the rolled piece: L.
7. A side guide plate control device for a hot roll mill, characterized in that, include: The first acquisition module (110) is used to acquire the rolling passes of the hot roll mill and the parameters of the rolled piece for each pass in response to user input. The second acquisition module (120) is used to acquire the current rolling pass and the current rolled piece parameters; wherein, the current rolling pass is used to characterize the current number of times the hot roll mill rolls; The position determination module (130) is used to determine the position of the side guide plate according to the current rolling pass; The opening degree determination module (140) is used to determine the opening degree value of the side guide plate according to the position of the side guide plate and the current rolling parameters; The control module (150) is used to control the side guide plate to move according to the opening value so that the opening amount of the side guide plate reaches the opening value.
8. An electronic device, characterized in that, include: A memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor, when executing the program, implements the control method as described in any one of claims 1-6.
9. A computer-readable storage medium, characterized in that, The computer-readable storage medium stores computer-executable instructions, which, when executed by a processor, are used to implement the control method as described in any one of claims 1-6.
