Zusammenfassung:	FIELD: metallurgy; preparation of materials for melting iron and making steel; production of molten iron and steel for production of various castings. SUBSTANCE: proposed briquette includes screenings of iron shot, 92.0-96.95; water glass, 3.0- 7.5; sodium fluosilicate, 0.05-0.5; water, above 100 % in the amount of 0.4-1.1 of mass of water glass. Said components of charge are mixed and molded in flexible mold; before drying, sump is laid on mold and mold is turned through 180 deg.; drying is performed at temperature of 150 to 250 C continued for 2 to 3.5 hours. Used as binder is aqueous solution of water sodium glass at modulus of 2.3-3.0 and density of 1.1-.5 g/cu cm. Use of small articles in briquetted form reduces considerably their loss in storage and use enhancing their activity. EFFECT: enhanced efficiency. 3 cl, 5 tbl
