Problems solved by technology

For the second case, it is mainly to adjust the process parameters, mainly to adjust the lead rate of the laying machine. This method is often tried, because it can be adjusted while producing and will not cause production interruption. However, due to lack of directionality and Quantitative guidance is often not only not adjusted well, but also leads to more serious spinning disorder, so that it is forced to stop and change the spinning tube

Abstract

The invention discloses a high-line wire-drawing control method and system, a storage medium and computer equipment. The method comprises the following steps: acquiring the torque of a high-line wire-drawing machine during no-load; acquiring the torque of the high-line wire-drawing machine in real time during wire drawing when the high-line wire-drawing machine performs wire drawing; comparing thecurrently acquired torque of the high-line wire-drawing machine during wire drawing with the torque of the high-line wire-drawing machine during no-load, judging the size relation of the two torques,and regulating the lead rate of the high-line wire-drawing machine according to the size relation of the two torques, wherein if the former is smaller than the latter, the lead rate of the high-linewire-drawing machine is increased until the two are equal; and if the former is greater than the latter, the lead rate of the high-line wire-drawing machine is decreased until the two are equal to each other. According to the high-line wire-drawing control method disclosed by the invention, the wire drawing quality of the high-line wire-drawing machine can be rapidly, accurately and simply controlled in real time, the phenomena that wire drawing circles have different sizes and arrangement between the circles is non-uniform due to wire drawing disorder of the high-line wire-drawing machine canbe avoided, and the failure conditions that steel is blocked by an air-cooled roller way, the steel is blocked by a collecting reel and the like can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a control method, system, storage medium and computing equipment for high wire spinning. Background technique [0002] Since the high line has been put into production, there has been a problem of spinning disorder. Various adjustments and adjustments have been made, but the problem has not been completely solved. Moreover, the problem of spinning disorder has many uncertainties, because there are many factors that affect the quality of spinning, such as spinning tube, steel temperature, speed matching, etc. If spinning disorder occurs during the normal rolling process, it is a serious problem. It is a very tricky thing. On the one hand, if it is not adjusted, it will lead to failures such as air-cooled roller table jamming and steel reel jamming. At the same time, it will cause large and small circles and uneven arrangement between circles. There are two optio...
