PROCEDURE FOR PREPARATION OF OILED AND NOT OILED CHARGE MATERIALS IN FORM OF FLUXED BRIQUETTES TO SMELTING Russian patent published in 2011 - IPC C22B1/248 C22B7/00 

Abstract RU 2429302 C2

FIELD: metallurgy.

SUBSTANCE: procedure consists in mixing preliminary prepared iron containing waste of metallurgical production with crumbled carbon containing substance at amount of 15-60% of carbon from weight of waste and binding. Produced mixture is treated with water solution of Na2O·n·SiO2, pressed and dried. Also, iron containing waste is preliminary treated with suspension of system Ca(OH)2-H2O produced by roasted lime slaking with wader and containing 50-60% of calcium hydroxide and dried. As iron containing waste there is used oiled or not oiled scale of various origin.

EFFECT: reduced content of phosphorus in alloys on base of iron melted with fluxed briquettes.
