Monitoring of Centrifugal Cast Rolls Using Acoustic Emission
نویسنده
چکیده
The seven centrifugal cast rolls were on-line monitored by using acoustic emission (AE) method till seven days after pouring. AE technique is suitable method, since the signal is generated naturally by abrupt localized changes in stress in a solid [1]. The aim of this work was to optimize the cooling rate and to investigate the effect of scrap quality (for melting process) on the internal quality of rolls. The evaluation of AE records (counts rate versus time) revealed, that the quality of rolls is affected mainly by:

In this study, the change at rubbing surfaces has been investigated experimentally using an acoustic emission signal monitoring system. A steel ring is slipped on the surface of a metallic sheet to simulate frictional conditions. The mechanical disturbances caused by the movement of the ring produce stress waves propagating along the sheet surface. The out of plane displacement of the sheet su...
