Mechanism of assimilation of iron-containing silicon carbide briquettes, which are put during the steel production in bof to reduce the consumption of hot metal

Briquettes are prepared from slag of silicon carbide production and scale in a ratio of 1:1 and used in a BOF charge. Their application has reduced the consumption of hot metal by 2.6 kg per 1 kg of briquettes and showed: 1) the process of briquette dissolution in the melt is determined by the diffusion of silicon and carbon and occurs after the disruption SiO2 film on the SiC surface caused by the thermal shock ; 2) the process in the slag melt is determined by the chemical interaction of SiO2 from the surface film with the components of the converter slag with the formation of low-melting compounds with FeO and further transfer of the reaction products.
