The modern methods of investigation of the crystallization process in the continuous casting crystallizer are observed in the article. In the context of continuous casting the method of the horizontal probing involving the use of the probe, fastened on a turning mechanism, and recording data using a protractor arouse interest. The main disadvantage of this method is the use of a rotary mechanism, which results in design complication and reduces the accuracy of experimental results. In order to eliminate this drawback, a new non-destructive method of oblique probing of continuous casting is proposed in the article. The method involves the application of a steel rod, which is introduced at a certain angle into the melt until it stops in the formed crust of metal. Then, the crust thickness can be determined by using the difference of length of the section of the rod introduced into the melt before casting mold and after finding the metal crust. The study takes place at several levels of the mold, which makes it possible to investigate the formation of cortical areas blank in the mold during the casting process more accurately. The research of crust at several horizons is due to the metal shrinkage during casting, as well as the probability of forming gaps between the wall of the mold and metal crust. The method makes it possible to research the crust growth just during casting, and thereby to adjust the process parameters for producing casting with high quality of metal surface
