THERMITE MIXTURE FOR FORMATION OF GRANULES USED FOR OXIDISING REFINING OF IRON-CARBON ALLOYS Russian patent published in 2013 - IPC C12C7/00 

FIELD: metallurgy.

SUBSTANCE: thermite mixture includes potassium nitrate, iron-bearing wastes in the form of sawdust, chips and shot production wastes, bighouse dust with oxidation degree Fe⁺², Fe⁺³ at the following dry mass component ratio, wt %: Potassium nitrate 58-63; Iron-bearing materials 26-34; Bighouse dust 8-11.

EFFECT: initiation of self-propagating high temperature synthesis (SHS) process in a granule allows performing heat treatment of granules without connection of any external energy sources.
