SOOTY IRON PRODUCTION METHOD Russian patent published in 2008 - IPC C21B13/00 C21B15/00 

FIELD: metallurgy of iron.

SUBSTANCE: method comprises steps of mixing iron-containing components with carbon-containing reagents being technical carbon produced at process of thermal-oxidation decomposition or thermal decomposition of hydrocarbons; providing reaction of iron containing components heated and soaked in furnace with carbon-containing reagent for depositing finely dispersed carbon on surface and also in macro- and micro-pores of iron-containing component volume; creating in furnace protection atmosphere due to feeding nitrogen into furnace; cooling produced sooty iron in furnace. Invention allows shorten time period of production of sooty iron and increase by 2.9 - 4.5 times efficiency of said process.

EFFECT: improved efficiency of method, shortened duration of process for producing sooty iron.
