PROCEDURE FOR PREPARATION OF OILED AND NOT OILED CHARGE MATERIALS IN FORM OF FLUXED BRIQUETTES TO SMELTING

摘要

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.;3 cl, 3 tbl, 3 ex
