Abstract
PURPOSE: To regulate a necessary amount of O2 simply without being limited by conditions of the lance pipe and the burner by blasting of lower pressure gas to the splash formed in case of blast smelting raw material such as metal sulfide ore etc. with medium pressure gas with the lance pipe.
CONSTITUTION: Medium pressure air etc. is supplied to the melt 3 in a smelting furnace 1 by the lance pipe 2, the splash 5 is formed. E.g. air delivery port 4 is provided at the ceiling of the furnace, air from its bears a part of splash oxidation. If either it is difficult to provide the delivery port 4 in the furnace, or air supply amount for fuel from the burner 6 can afford it, air supply from the burner 6 may be increased. Thus, the splash 5 contributes to the oxidation reaction, and because this reaction is exothermic, the heatloss due to excess air decreases.
