摘　　要：高温熔融金属容器设备的智能调度优化是冶金流程智能化发展的重要一环,其识别跟踪定位技术是最为关键的技术之一。冶金工业工厂环境温度高、金属多,尤其是高温熔融金属容器表面温度高、钢渣散落,如何在这样恶劣的工作环境下还能精准定位是技术难点。该文研究基于电磁微声技术设计了一种新型层状结构的高温压电微声芯片,电极采用Ti/Al多层结构设计。该文搭建了新型高温实验自动数据采集平台,实现高温条件下器件电学性能及耐高温性能的实时精确测量,芯片实测最高工作温度达到550,器件插入损耗不超过35dB,可以实现较远距离识别。该技术在宝钢湛江钢铁和陕西龙门钢铁有限责任公司进行了实际应用,验证了基于电磁微声技术的识别技术具有长期免维护的显著优势。该技术解决了高温熔融金属识别跟踪的难题,助力冶金流程智造。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 acqui sition 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◦C and the insertion loss of the device does not exceed−35 dB,which can realize relatively long distance recognition.This technology has been applied in Zhanjiang and Long men 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.
