AI Technical Summary

Technical Problem

Existing methods for detecting hydrogen content in copper melts cannot guarantee the timeliness of detection at different stages of the dehydrogenation process, and are prone to repeated detection when the hydrogen content is relatively stable. They cannot adapt to the rapid changes and spatial distribution differences in the hydrogen content of copper melts.

Method used

By simultaneously acquiring the acoustic response signal and spatial temperature distribution signal of the copper melt, and based on the acoustic characteristic parameters and response region division, a mapping model is constructed, and the acquisition parameters and sampling weights are dynamically adjusted to achieve the acquisition of spatiotemporal distribution information of hydrogen content and optimization of detection strategy.

Abstract

This invention relates to the field of hydrogen content detection technology in copper melts, and particularly to a method for detecting hydrogen content in copper melts based on ultrasonic dehydrogenation. The method includes: simultaneously acquiring acoustic response signals and spatial temperature distribution signals of the copper melt; extracting acoustic feature parameters related to hydrogen content based on the acoustic response signals, and dividing the melt space into multiple response regions based on the spatial temperature distribution signals; inputting the acoustic feature parameters and spatial information of the response regions into a pre-constructed mapping model to obtain the spatiotemporal distribution information of hydrogen content; extracting temporal evolution features and spatial change features based on the spatiotemporal distribution information; adjusting the acquisition parameters of the acoustic response signals and the sampling weights of each response region according to the temporal evolution features and spatial change features, and performing signal acquisition and updating of the spatiotemporal distribution information of hydrogen content in the next cycle. This invention enables dynamic and accurate detection of hydrogen content in copper melts, adapting to the spatiotemporal dynamic changes of hydrogen content during the dehydrogenation process.
