Abstract

The invention relates to the technical field of converter gas supply, in particular to a converter bottom blowing gas supply device which comprises a furnace body. An oxygen pipe used for conveying oxygen is arranged at the top of the furnace body, an inert gas pipe used for conveying inert gas is arranged at the bottom of the furnace body, a gas supply box is arranged at the bottom of the furnacebody, an installation plate is arranged in the gas supply box, through grooves distributed in an array mode are formed in the plate surface of the installation plate, the bottom end of each through groove is provided with a conveying pipeline in an inserted mode, the top end of each through groove is provided with a pressurization pipeline in an inserted mode, and the top ends of the conveying pipelines are in butt connection with the bottom ends of the pressurization pipes. The problem that a gas supply device cannot guarantee that sufficient inert gas is conveyed to a converter for steelmaking and influence steelmaking quality is solved, and sufficient inert gas can be introduced into the converter through pressurization, so that molten steel in a molten pool is stirred more uniformly,and molten steel smelting quality is obviously improved.

Description

technical field [0001] The invention relates to the technical field of converter gas supply, in particular to a converter bottom blowing gas supply device. Background technique [0002] During the smelting process of the converter, oxygen is blown from the top of the furnace and inert gas is blown from the bottom of the furnace to uniformly stir the molten pool, which can make the reaction of the molten pool close to equilibrium, which not only improves the quality of molten steel, reduces the cost per ton of steel, but also increases the flexibility of the converter and adaptability, improve the ability of the converter to melt scrap steel, so that the amount of scrap steel entering the furnace can be flexibly changed according to changes in market scrap steel and molten iron prices, thereby obtaining economic benefits. Under the existing technology, the inert gas is blown into the furnace from the bottom of the converter, due to The pressure generated by the high temperatu...
