Abstract
The invention discloses a tuyere sleeve to connect vent oxygen pipe in the iron-smelting furnace or steel-smelting furnace, which comprises the following parts: flannel, vent sleeve bulk and cooling water conduct liner, wherein the vent is set on the flannel; the cooling water conduct inner connects the flannel, which is plugged in the vent sleeve bulk cavity with conductive sleeve; the spiral conduct piece is set on the conduct sleeve; the flannel and cooling water conduct liner is made of iron; the vent sleeve bulk is made of copper; the cooling water inlet and outlet are set on the flannel; the cross section of inlet and outlet displays conical shape in the vent sleeve; the inlet and outlet are set at the connecting position of conduct sleeve and flannel; the liner of cooling water conduct liner welds flannel directly.
Description
Technical field
What tuyere cover of blast furnace of the present invention related to is the air port cover in air-supply oxygen deliverng pipe road in a kind of iron-smelting blast furnace or the steel melting furnace.
Background technology
Steel melting furnace, the manufacturing of the whole employing of ironmaking tuyere of blast furnace cover copper material at present, cost height, internal structure complicated processing be difficulty relatively.Cover is bolted to connection with flange in the water coolant, overlaps with the easy seepage in flange connection portion in the water coolant, can influence air port cover cooling performance.Can burn out the air port cover when serious, influence the stove ordinary production.
Summary of the invention
The objective of the invention is provides a kind of tuyere cover of blast furnace at above-mentioned weak point, the flange and the air port body of air port cover, adopt two kinds of different metal materials to constitute, flange adopts iron quality metal material to constitute, the air port body adopts copper metal material to constitute, and cover can adopt iron quality metal material to constitute in the water coolant water conservancy diversion.Because cover adopts iron quality metal material in flange, the water coolant water conservancy diversion, can save the noble metal copper material, reduce cost greatly, increase air port cover intensity, improve result of use.
Tuyere cover of blast furnace is to adopt following scheme to realize: the structure of tuyere cover of blast furnace comprises cover in flange, air port body, the water coolant water conservancy diversion.Flange is provided with blast inlet, also is provided with the water coolant entery and delivery port.Cover is connected with flange in the water coolant water conservancy diversion, and the interior suit of water coolant water conservancy diversion is inserted in the air port and overlaps in the intracoelomic cavity, the air port body can be directly and flange integrally welded.Flange adopts iron quality metal material to constitute.The air port body adopts copper metal material to constitute.
Cover has the water conservancy diversion cover in the water coolant water conservancy diversion, and the water conservancy diversion cover is provided with the volution inducer, is provided with pod apertures in the water conservancy diversion cover, is provided with entery and delivery port at the water conservancy diversion cover with flange connections, is connected with entery and delivery port on the flange respectively.Cover adopts iron quality metal material to constitute in the water coolant water conservancy diversion.
Principle of work:
Tuyere cover of blast furnace is installed in ironmaking or steel melting furnace air-supply oxygen deliverng pipe road ventilation opening end when using, the pressed gas of sending here by air supply duct through blast-furnace tuyere cover into be used in the body of heater combustion-supporting etc.Water coolant enters the interior process of cover volution inducer water conservancy diversion in the spirrillum water coolant water conservancy diversion by air port cover, flange cooling water intake place.In water coolant water conservancy diversion cover, carry out volution circulation (seeing arrow indication explanation in the accompanying drawing) and, the air port body is fully cooled off, in order to avoid high-temperature gas burns out tuyere cover of blast furnace in the blast furnace after cooling water outlet is got back to the refrigeration cycle return water pipe.
Tuyere cover of blast furnace is reasonable in design, compact construction.Cover in the flange of air port of the present invention cover, air port body, the water coolant water conservancy diversion, adopt two kinds of different metal materials to constitute, flange adopts iron quality metal material to constitute, and the air port body adopts copper metal material to constitute, and cover can adopt iron quality metal material to constitute in the water coolant water conservancy diversion.Because cover adopts iron quality metal material in flange, the water coolant water conservancy diversion, can save the noble metal copper material, reduce cost greatly, increase air port cover intensity, improve result of use.Because the air port body adopts copper metal material to constitute, cooling heat dissipation is effective.Cover directly and flange welds in the water coolant water conservancy diversion, good seal performance.
Description of drawings
The invention will be further described below with reference to accompanying drawing.
Fig. 1 is the tuyere cover of blast furnace front view.
Fig. 2 is a tuyere cover of blast furnace A-A sectional view.
Fig. 3 is a tuyere cover of blast furnace B-B sectional view.
