PROCEDURE FOR PREPARATION OF CHARGE FOR MANUFACTURE OF METALLISED PRODUCT Russian patent published in 2011 - IPC C22B1/243 

FIELD: metallurgy.

SUBSTANCE: procedure consists in metered mixing oxide-containing material with carbon containing reducer, in supply of silica containing binding, in sintering, and in thermal treatment of manufactured agglomerates. Liquid glass is supplied to source mixture as a silica containing binding. Heat treatment of iron-carbon containing agglomerates is performed in rising and descending flows of gases which are supplied from a heat exchanger of cooling of kiln gases of a metallisation furnace. Temperature at heat treatment of agglomerates is maintained at 350-400°C.

EFFECT: reduced losses of charge material, reduced temperature and time of heat treatment.
