The positive influence of vibropacking before isostatic pressing is caused by the effects of vibration breaking of the structural 'arched' formations in dispersed media and is revealed in obtaining blanks of uniform and high density. These phenomena are used most rationally in vibropacking powders in vacuum. For this it is necessary to use a design of container vibrating with harmonic oscillations with an inertia-free overload. A method of isostatic pressing with preliminary vibrovacuum packing and a hydraulic over load has been developed. A feature of the method is pouring of the material into the mold with vibration and then repeated vibropacking of the evacuated powder with the use of an overload. The method makes it possible to obtain large high-quality refractory parts of complex configuration. [ABSTRACT FROM AUTHOR] |
