The invention relates to an online treatment device for iron making hot blast furnace base blowby pressured gas and an installing method. The online treatment device is characterized in that the hot blast furnace base blowby pressured gas defect treatment device is composed of strengthened rib plates, a cover plate, a ring plate, a seal structure installing groove, a seal pouring body I, a seal pouring body II, a seal pouring body III and a seal pouring body IV; the seal structure installing groove can be formed in the connecting position of a hot blast furnace body bottom plate and a cement base in the blast furnace online production period, the seal pouring bodies are formed in the seal structure installing groove structure through filled seal materials, the blowby gas is blocked at theouter portion of a hot blast furnace body, and the pressured gas blowby defect is effectively treated online; a repaired hot blast furnace seal system can seal the connecting position of the hot blastfurnace body bottom plate and the cement base, pressured gas blowby is effectively blocked, the hot blast furnace can conduct production with full air, the blast furnace production running coefficient is improved, the blast furnace yield is improved, and higher economic benefits are created.
Description
technical field [0001] The invention belongs to a kind of metal smelting equipment in the ironmaking system of iron and steel enterprises, which is used for air preheating and heating during the ironmaking combustion process of the blast furnace, and sends high-temperature superheated gas with pressure into the blast furnace to support combustion and is a hot blast stove for the supporting production of the ironmaking blast furnace The system device relates to an on-line treatment device and installation method for leakage of pressurized gas defects in the foundation of a hot blast stove in an ironmaking system, and in particular to an on-line treatment device and installation method for leakage of pressurized gas in the foundation of an ironmaking hot blast stove. Background technique [0002] At present, the domestic metallurgical industry traditionally adopts blast furnace ironmaking in the existing technology. When the lower sealing structure in the hot blast stove partia...
