Alumina coatings on carbon bonded alumina nozzles for active filtration of steel melts
Source abstract
Abstract
Abstract Slip casted, carbon bonded nozzles with and without alumina based active coatings have been simultaneously tested in a novel casting simulator according to their clogging behavior against endogenous as well as exogenous non-metallic inclusions. Computer tomography images as well as SEM micrographs support the investigation of the clogging areas. The nozzle with the alumina active coating leads to increased clogging phenomena based on endogenous and exogenous inclusions as well as steel clogged particles. Correlating the clogging to a type of improved “filtration efficiency”, a higher filtration of steel melts is expected with the application of alumina active coatings on carbon bonded filters.
