Strip steel coiling method, device and equipment and storage medium

Abstract

The invention relates to the technical field of hot-rolled coiled plate production, in particular to a strip steel coiling method, device and equipment and a storage medium. The method comprises the steps that in the process of coiling strip steel through a coiling machine, heat detection is conducted through a first temperature measuring device and a second temperature measuring device; when the first thermal detection signal measured by the first temperature measuring device is lost and the second thermal detection signal measured by the second temperature measuring device exists, a loss detection operation is started by the second temperature measuring device; and in the process of starting the detection operation through the second temperature measuring device, that the second thermal detection signal is lost is detected, and tail fixing operation is carried out on the strip steel. Through the loss of the first thermal detection signal and the existence of the second thermal detection signal, the method can accurately determine whether the tail part of the strip steel is coiled or not; and on the basis of accurately determining whether the tail part of the strip steel is coiled or not, the coiling accuracy of the tail part of the strip steel can be further improved, so that the coiling accuracy of strip steel coiling can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of hot-rolled coil production, in particular to a strip coiling method, device, equipment and storage medium. Background technique [0002] At present, in the hot rolling production line, in order to realize the automatic strip rolling process, the automatic coiling of the strip is realized. The specific operation is: when the thermal detection signal of the thermal detector installed in front of the coiler is lost, a fixed Tail timing sequence, when the tail of the strip reaches the position of the coiling helper roller of the coiler, the first tail is fixed; after success, the coiler slows down and stops, and the second tail is started, and the tail of the strip is rotated to the predetermined position. The position is so that the tail of the strip is pressed by the roller of the unloading car during the coil unloading process, so as to ensure that when the stress of the high-strength steel tail is large, ...

Problems solved by technology

[0003]However, when the tail of the strip has a low temperature, or the temperature of the tail of the strip is lower than the detection threshold of the thermal detector, the timing of tailing will be triggered in advance, The tail of the strip is stuck at the valve of the coiler. When the next strip arrives, the head of the strip cannot pass through normally, resulting in stacked steel, so that the accuracy of strip coiling is low.

When the thermal detector is working, it is prone to false signals, which triggers the tail-fixing sequence, and because the tail-fixing sequence is a PLC interrupt sequence, it is impossible to add the filtering effect of the thermal detection signal, causing the tail of the strip to fly or the next strip to head The steel stacking accident caused by the early triggering of the tailing sequence at the end will also lead to the problem of low accuracy of strip coiling
