Band steel deflection and floating quantity laser scanning detection method and deflection correction system

Abstract

The invention discloses a band steel deflection and floating quantity laser scanning detection method, which comprises the following steps that: 1) a linear laser emitter is used for irradiating the band steel, and a laser linear light beam is formed on the band steel in the width direction; 2) a plane array image sensor arranged above the band steel is used for scanning the laser linear light beam in real time; 3) the scanned laser linear light beam is sent into a computer, and the computer determines the band steel edges according to the laser linear light beam; and 4) the band steel deflection quantity can be calculated according to the band steel edges determined by the computer at different moments, and simultaneously, the upwards and downwards floating quantity of the band steel canbe calculated according to the displacement quantity of the laser linear light beam in the length direction of the band steel. The band steel deflection and floating quantity laser scanning detectionmethod has the advantages that the cost is low, the detection precision is high, the real-time performance and the anti-jamming capability are high, the long-time stable operation can be realized in complicated environment, the band steel deflection automatic detection level is favorably improved, the installation and the maintenance of equipment are convenient, and the technical support is provided for the efficient production of the band steel.

Description

technical field [0001] The invention relates to a laser scanning detection method for deviation and floating amount of strip steel and a deviation correction system. It can also be applied to continuous casting slab, billet shape detection, and other strip correction applications (such as: light metal industry, copper industry, printing and binding industry, papermaking and rubber chemical industry, etc.) real-time detection, belonging to the field of metallurgical technology . [0002] Background technique [0003] Strip continuous processing units often have deviations during strip threading and production. As a result, not only strip defects occur and the yield decreases, but also the normal operation of the unit is affected and production equipment is damaged, which in turn leads to a decline in overall production capacity. Strip correction system (Edge Position Control, referred to as EPC) is a common technology in the rolling production line, which is widely used in ...

AI Technical Summary

Problems solved by technology

At present, the detection technology in this field abroad is relatively mature, but the technology is complicated, the cost is high, and the equipment is expensive. However, the strip deviation detection and control system independently developed in China is basically zero. The main reason is that the design technology of the sensor is immature and the detection accuracy low, and does not guarantee long-term reliable operation
