METHOD FOR BLOWING-IN OF BLAST FURNACE AFTER LINING REPAIR BY METHOD OF GUNNING Russian patent published in 2009 - IPC C21B3/00 

Abstract RU 2350657 C2

FIELD: technological processes; metallurgy.

SUBSTANCE: invention is related to the field of ferrous metallurgy, in particular to blast-furnace production. Method includes supply of combined blast, loading of blowing charge coke into peripheral zone of furnace with fraction of more than 40 mm and thermal treatment of fire-resistant lining with provision of gas-charge medium temperature in the area of lining gunning in interval of 750-1400°C for 5-8 hours from the moment temperature of 750°C has been achieved, and further blast mode and system of loading according to parameters of blowing period and working mode of blast furnace.

EFFECT: increased service life of lining and increased production of smelt liquid products in overhaul periods.
