| The intelligent scheduling optimization of high-temperature molten metal container equipment is an important part of promoting the intelligent development of metallurgical processes. It relies on advanced perception technology to obtain information, and recognition, tracking, and positioning technology is the most crucial. The environment of metallurgical industry factories is high in temperature, with a large amount of metal. The surface temperature of high-temperature molten metal containers is high, and steel slag is scattered. How to resist such harsh working environments is a technical challenge. In this essay, a novel high temperature piezoelectric micro-acoustics chip with layered structure is designed based on Electro-Magnetic Micro-Acoustics (EMMA) technology. The electrode adopts Ti/Al multi-layer structure. Build a new automatic data acquisition platform for high temperature experiments to achieve real-time and accurate measurement of electrical performance and high temperature resistance of devices under high temperature conditions. The maximum operating temperature reaches 550℃ and the insertion loss of the device does not exceed -35dB, which can realize relatively long distance recognition. This technology has been applied in Zhanjiang and Longmen Iron industry, verifying the significant advantage of EMMA based recognition, tracking, and positioning technology in long-term maintenance free. The technology has solved the problem of identifying and tracking high-temperature molten metals, assisting in the intelligent manufacturing of metallurgical processes. |
