Nondestructive control of physico-mechanical properties and quality of graphitized carbon products

The opportunity and expediency of use of the acoustic quality monitoring based оn measurement of natural oscillation frequencies of articles, for an estimation of physicomechanical properties and quality the bottom blocks burnt and not burnt (“green”) anodes of electrolyzers is displayed. The results of acoustic monitoring expressed in sound indexes, can be effectively used at prediction of working capacity of carbon articles used by manufacture of aluminium.
