METHOD OF PRODUCING BRIQUETTE FOR DEOXIDIZING STEEL Russian patent published in 2017 - IPC C21C7/06 C22B1/248 

FIELD: metallurgy.

SUBSTANCE: method includes pressing secondary aluminium and iron, at that the ground chip waste of mechanical processing of thermally strengthened Al-Si-Mg system alloy containing at least 89.6% aluminium, and crushed product of metallurgical scale reduction is mixed in the ratio of 25-50:75-50 wt %. The mixture is pressed to the density of 0.45-0.65 of theoretically possible, pressed briquettes are subjected to washing for cleaning from cutting fluid, repeatedly pressed to density of 0.75-0.90 of theoretically possible. On the surface of the briquettes there is a protective shell formed by dipping into suspension based on liquid glass with added particles of metallurgical scale reduction product.

EFFECT: increased duration of storage, transportability and deoxidation efficiency of liquid steel with aluminium.
