Judgment method for axial force of rolling work roller

Abstract

The invention relates to a judgment method for axial force of a rolling work roller. An oil pressure sensor is additionally arranged on a rod side hydraulic pipeline of a work roller shifting cylinder, and an oil pressure curve graph is drawn for visual display. The axial force of the work roller of a rolling mill is dynamically monitored in real time, the axial bearing condition of a work rollerbearing in the rolling process is monitored, and axial force historical recording and querying are provided. A reminding function on bearing box inspection and repair is achieved, the bearing box is prevented from being burned out, and real beforehand prevention of accident control is achieved. Accidents are effectively reduced, the economic loss caused by accidents is effectively reduced, and thebenefits of an enterprise are increased. In addition, the state of the levelness and precision of the rolling machine can be embodied according to the axial force, and a favorable basis is provided for recovery of the precision and levelness of the mechanical equipment.

Description

technical field [0001] The invention relates to the technical field of hot-rolled strips, in particular to a method for judging the axial force of rolling work rolls. Background technique [0002] It is understood that at present, more than 65% of the domestic hot rolling mills are roll-shifting finishing mills. The axial connection mode of the work rolls is that the end of the work rolls is equipped with a bearing box. The fixed and roll shifting slider is connected to one end of the work roll hydraulic cylinder, and the other end of the work roll hydraulic cylinder is connected to the rolling mill archway. During hot rolling production, the work roll bearing "burning box" damage phenomenon often occurs (work roll bearing burning box: generally refers to the bearing rollers in the work roll bearing box are stuck and cannot rotate, and the bearing is burned). Through Internet search and on-site production experience, the burning of work roll bearing box bearings is mainly r...

Problems solved by technology

However, during the production process, the burning of the work roll bearing box will cause the production line to stop rolling, the work roll needs to be replaced, and the dimensional accuracy of the rolling mill needs to be checked and restored, which greatly affects the production efficiency and brings great losses to the steel mill. loss
