Abstract

Microfabricated thin-film thermocouples (TFTCs) and Fiber Bragg Grating (FBG) sensors can be embedded in the coating layers of the mold during electroplating to measure temperature, heat flux, and strain during continuous casting. Embedding sensors within 1mm near the surface has the advantages of sensitive real-time monitoring of thermal behavior without damping by the copper mold, and protection from the hostile environment. A method to embed TFTCs and FBG optical fibers in a coating layer was developed, implemented and tested. The signal output by FBG sensors embedded in a nickel coating layer on a copper mold has been investigated and can be predicted with simple equations. These sensors are able to monitor both temperature and strain in real time during casting operation with high resolution.
