Problems solved by technology

[0005] However, in actual operation, due to the cross-influence of the above factors, it is impossible to formulate a single current value judgment standard to monitor the abnormal production of the rolling line, judge whether the rolling line is running normally, and give an early warning

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] Example: such as figure 1 and 2 As shown, a current tracking method for abnormal rolling line production, the rolling line production system includes a multi-stand rolling mill and a rolling line monitoring system, the rolling mill includes KI, K2, K3-Kn multiple passes, K1 is the finished pass rolling mill, K2 is the rolling mill before the finished product, K3 is the rolling mill before the finished product, Kn is the initial rolling mill, and the operation steps of the rolling line monitoring system are as follows:

[0036] (1), the steel billet enters from Kn (the first frame) and starts rolling operation;

[0037] (2) When Kn bites the steel, the rolling line monitoring system starts to work;

[0038] (3) The rolling line monitoring system includes a time relay. The time relay is controlled for 30 minutes in advance. The rolling line monitoring...

Abstract

The invention discloses a current tracking method for rolling line production abnormity. The current tracking method mainly comprises the steps that at the time when the production state is just established, a rolling line monitoring system automatically collects and analyzes current values of motors of all rolling mills, a control interval target value of the current is automatically set according to the maximum limit value and the minimum limit value of the current values and serves as the judgment standard, the current under the subsequent stable-state production condition is checked, if the value of the current of a certain motor frequently exceeds the interval target value, then it means the corresponding rolling mill on a rolling line has production abnormity, an alarm system is started at the same time to remind site operation personnel to deal with the production abnormity in time, and otherwise, production is normal.

Description

technical field [0001] The invention relates to the field of steel rolling production detection, in particular to a current tracking method for abnormal production of a rolling line. Background technique [0002] With the advancement of steel rolling technology, modern steel rolling enterprises pay more and more attention to output, quality, cost and benefit, and develop towards scale, specialization, automation and intelligence. In order to obtain the greatest competitive advantage, enterprises must discover and reduce production abnormalities in time, realize normal and stable production, reduce production costs, and reduce hidden dangers of product quality. [0003] The main steel rolling line is composed of large and medium-sized equipment such as motors, gearboxes, rolling mills, guides and guards. During production, the operation speed is fast and the rolling load is heavy. It has always been a frequent area for production abnormalities (faults). The existing rolling l...
