Abstract

The invention provides a method and a system for maintaining a mill tensiometer. The method comprises the steps of detecting mill interstand tension by adopting pressure heads of the tensiometer; using the pressure heads of the tensiometer on the operating side and the driving side as collecting sources, and obtaining tension values from the collecting sources; judging whether the tension values obtained from all of the collecting sources are abnormal, and determining the collecting source of the failure side if the tension values are abnormal; and giving up to obtain the tension value of thecollecting source of the failure side, and replacing the tension value of the collecting source of the failure side with the tension value of the collecting source of the non-failure side. When the detection of the tensiometer on single side is abnormal, the tension value of the failure side can be replaced with the tension detection numerical value of the normal side for production by adopting the method, so that high-speed strip breakage and shutdown are avoided. Onsite multiple simulation tests indicate that the method is really feasible.

Description

technical field

[0001] The invention belongs to the technical field of rolling, and in particular relates to a method and system for maintaining a rolling mill tensiometer. Background technique

[0002] In the 1420 acid tandem rolling production line of Shougang Jingtang Company, ABB tensiometer pressure head is used for tension detection between rolling mill stands. Tension is an important parameter in the production process of tandem cold rolling. The performance of tension control between stands directly affects the continuous operation of the production line, and the accuracy of tension detection is the most basic condition for tension control. Since it was put into production in August 2013, the pressure head of the tensiometer between the racks has been damaged one after another. The frequent abnormal operation of the tensiometer indenter will not only cause a large number of out-of-contract products due to the broken belt in the rack, but also the processing of a bro...

Examples

Embodiment 2

[0063] image 3 It is a schematic diagram of system communication for rolling mill tensiometer maintenance in Example 2 of the present invention. see image 3 , on the basis of the system in Embodiment 1, the system in Embodiment 2 of the present invention may further include:

[0064] The display unit is used to display the tension values ​​obtained from each collection source and the position of the collection source with abnormal tension values;

[0065] The alarm unit is used to alarm and remind the operator that the tension value of the acquisition source is abnormal.

[0066] Specifically, each unit of the system will be described respectively below with reference to the accompanying drawings.

[0067] by image 3 Take the system of Embodiment 2 as an example, the tension value is detected by the ABB tensiometer pressure head, and transmitted to the tensiometer control cabinet, and the tensiometer control cabinet communicates with the Hitachi R700 processing system. ...
