PROCESS OF PRODUCTION OF METALLIZED CHARGE Russian patent published in 1998 - IPC

FIELD: production of metallized charge. SUBSTANCE: process of production of metallized charge based on diatomite consists in crushing of rock, in its fractionation, annealing, in mixing of fraction (-0.63-0.10 mm) with halogenides of metals (5.0-20.0%) of CuCl₂,FeCl₃,AlCl₃ with subsequent heat treatment in accordance with technology of vibrating layer at temperature between 300 and 600 C in the course of 0.2-0.5 h. Starting mixture is added with 3.0-5.0% of ammonium chloride. EFFECT: degree of metallization amounts to 50-70% of surface of particles. 1 cl
