METHOD OF STRENGTHENING OF WET IRON-ORE PELLETS Russian patent published in 2015 - IPC C22B1/24 

FIELD: metallurgy.

SUBSTANCE: invention relates to ferrous metallurgy, and can be used for strengthening of wet iron-ore pellets. The method includes forming of the pellets by the wet charge pelletisation in pelletiser to provided the wet pellets with strength. Bentonite added to the charge prior to the above actions is treated in the pulse magnetic field of rectangular shape. Number of pulses is 20, magnetic field intensity of each pulse is 480 Oe, each pulse width is 0.2 s, and pause width between each pulse is 1.0 s.

EFFECT: invention increases strength of the wet iron-ore pellets, keeps iron high content in them, and reduces amount of the destructed particles during transportation to the baking machine for oxidising baking.
