METHOD OF COMPENSATION BLAST LOSSES IN FILLING OF AIR- HEATING BLAST FURNACE Russian patent published in 1995 - IPC

Abstract RU 2040547 C1

FIELD: metallurgy. SUBSTANCE: rate of blast, which is put on by a turbo-compressor unit, increases as soon as the air heater is filled proportional to the pressure in the collector of cold blast. After finishing the filling of the air heater and before setting it in 'blast' condition, the pressure regulator is changed over for controlling of the blower in the direction of 'discharging'. After cutting-off cooled air heater the pressure regulator is changed over for controlling 'charging' direction as well. In so doing, the cooled air heater is cutoff smoothly owing to the step closing of the cold blast gate, the port for filling being opened. After that the gate of the hot blast and port for filling of the gate of cold blast are closed. EFFECT: simplified method. 1 dwg
