METHOD FOR APPLICATION OF BY-PRODUCTS CONTAINING METAL OXIDE IN FERROCHROME MELTING PROCESSES Russian patent published in 2023 - IPC C22C33/04 C22B1/24 C22B4/00

Abstract RU 2804821 C2

FIELD: metallurgy.

SUBSTANCE: briquetting of by-products of metallurgical production in the form of powdered and finely dispersed metal oxide. The material containing metal oxides is from by-products of ferrochromium and quality steel production, and is briquetted using cement, and the briquettes are fed into a submerged arc furnace to produce ferrochromium.

EFFECT: increasing the yield of chromium in the alloy, reducing the amount of by-products of metallurgical production due to their processing.
