Chromite based refractory coatings used in expandable pattern casting of Fe-C alloys
Апстракт
A possibility to develop new chromite-based refractory coatings for casting applications has been investigated in this paper. The results of monitoring of synthesis and characterization procedure and finally application of the refractory coatings showed that sediment stability of coating suspension was crucial parameter for the quality of the coating. Optimization of the coating composition with the controlled rheological properties was achieved by application of different coating components, particularly by application of a new suspension agent and by alternation of coating production procedure. Chromite was applied as a filler. The chromite sample was tested by X-ray diffraction analysis, diffraction thermal analysis and scanning electron microscopy. The shape and grain size were analyzed with program package OZARIA 2.5. It was shown that application of this type of water-alcohol-based lining had a positive influence of surface quality, structural and mechanical properties of the cas...tings of Fe-C alloys obtained by casting into sand molds, according to the method of expandable patterns.
