METHOD OF PREPARATION OF CARBON-CONTAINING MASS FOR PRESSING OF DENSE REFRACTORY PRODUCTS Russian patent published in 2000 - IPC

Abstract RU 2160725 C2

FIELD: pressing of dense refractory products. SUBSTANCE: method includes metering and mixing of refractory filler, carbon-containing component and binder. Mixing process covers homogenization of mass to consistency corresponding to maximum mixing energy. Then, mass properties change such as its mobility (characterized by reduced energy consumed in mixing) and increase of bulk density. Process is carried out up to stabilization of mixing energy at minimal level and attaining of mass compression ratio equaling 1.3-2.1 determined by formula given in the invention description. EFFECT: higher density, reduced porosity of products and lower energy consumption in product pressing. 1 dwg, 2 tbl
