METHOD FOR PRODUCTION OF EXOTHERMAL MIXTURE FOR STEEL TREATMENT IN LIQUID STATE Russian patent published in 2005 - IPC

Abstract RU 2244754 C1

FIELD: iron metallurgy, in particular steel treatment.

SUBSTANCE: claimed method includes crushing of burning components and blending with reflux agent (e.g. synthetic calcium fluoride). Oxides of doping elements used as oxidizing components are premixed with melted reflux agent preliminary with lower melting point than the same of steel, at volume ratio preferably 1:1-1:5, respectively, cooled, crushed in form of failing, and introduced to mixture of burning components and reflux agent.

EFFECT: method with improved fire- and explosion safety.
