Abstract Macrostructure etching of continuous casting billet is one of the important parts of quality control in steel companies. For a long time, compared with the rapid development of automatic metallurgical analysis and products testing process, the value of automatic macrostructure etching process has been underestimated. With acid etching as the testing method, by comparing the different processing of sample preparation, acid etching and imaging, the development of the macrostructure etching process of continuous casting billet in domestic steel companies is reviewed and the future of automatic macrostructure etching process is discussed.
