Embodiment Construction

[0041] The embodiment of the present invention provides a hot rolling process control method and device, which solves the technical problem in the prior art that the operator fails to find the slab slipping in the area of ​​the slab in time, and realizes the guarantee of production quality and production efficiency. technical effect.

[0042] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0043] By judging whether the monitored torque value of the main motor of the side pressing block of the sizing machine is lower than the preset torque value, it is judged whether the slab is slipping in the sizing machine, so that the trigger signal prohibits the next slab from entering the sizing machine, Therefore, a quick response is realized when the slab slips in the width-fixing machine, which not only ensures the production quality, but also ensures the production efficiency. The embodi...

Abstract

The invention discloses a hot rolling technology control method and device. Whether a slab slips in a width fixing machine or not is judged by judging whether a monitored torque value of a side pressing block main motor of the width fixing machine is lower than a preset torque value or not, so that a signal is triggered to inhibit a next slab from entering the width fixing machine, and therefore quick responses are achieved when the slab slips in the width fixing machine. The production quality is guaranteed, and the production efficiency is also guaranteed. The judgment accuracy is high, andthe fault handling time is reduced by 50% or above.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a hot rolling process control method and device. Background technique [0002] At present, the rough rolling area of ​​hot rolling line 2250 has the characteristics of more equipment and wider coverage of monitoring points. At the same time, it is affected by factors such as few on-site operators and many monitoring blind spots. When the slab slips in the fixed-width machine area, it often occurs. , the operator failed to find out in time, which led to the occurrence of problems such as late discovery and untimely handling by the operator. In the case of a fast production rhythm, it may even cause a slab collision accident, which seriously affects the production quality and production efficiency. . Contents of the invention [0003] The present invention provides a hot rolling process control method and device, which solves the technical problem in the prior art that opera...
