COMPLEX STEEL OXIDAZER BASED ON LUMPY SILICON CARBIDE Russian patent published in 2017 - IPC C21C7/06 C22B1/243 

FIELD: metallurgy.

SUBSTANCE: lumpy silicon carbide (SiC) is used as material with a fraction more than 1 mm and moisture content less than 1% and its briquetted sifting of fraction less than 1 mm with final content in briquettes of basic element SiC 70-90%. Undersized SiC fractions less than1 mm briquetted with the use of beet molasses by vibrocompression into cylinders of up to 60 mm diameter and up to70 mm height or with the use of n inorganic binder with roller briquette press into tablets of up to 40 mm diameter and up to 30 mm height with strength of at least 400 kg/cm².

EFFECT: reduction of steel and cast iron production cost due to replacement of ferrosilicon with silicon carbide undersized fractions which surpasses ferrosilicon by technical characteristics.
