Abstract
The utility model relates to a furnace mouth tapping slot device for an argon oxygen refining furnace, belongs to the technical field of steel making equipment and aims to ensure that a furnace lining refractory material can be stably hung on a tapping hole, so that the service life of a furnace mouth tapping slot of the AOD furnace is remarkably prolonged. The furnace mouth tapping slot device has the technical scheme that the furnace mouth tapping slot device consists of a furnace mouth tapping slot, a refractory material and a heat-resisting cast iron plate, wherein the furnace mouth tapping slot is in a line shape; the refractory material is paved on the furnace mouth tapping slot, and an upper plane of the refractory material is flush with that of a furnace mouth; and the heat-resisting cast iron plate is arranged between the furnace mouth tapping slot and the refractory material. The furnace mouth tapping slot device has the beneficial effects that the position and the shape of the furnace mouth tapping slot are improved, and the furnace mouth tapping slot is changed from a U shape in the prior art into a line shape, so that the furnace lining refractory material can be stably hung on the tapping hole; the furnace material and the refractory material at the tapping hole of the furnace mouth are combined into a uniform whole body; and molten steel is not in contact with the furnace mouth tapping slot and a furnace shell directly, so that the temperature, the impact and the chemical corrosion can be most ideally borne, therefore, the service life of the furnace mouth tapping slot of the AOD furnace can be remarkably prolonged, and the service life of a whole furnace body is also prolonged.
Description
Technical field
The utility model relates to a kind of fire door device of argon oxygen decarburizing furnace, belongs to the steelmaking equipment technical field.
Background technology
Argon oxygen decarburizing furnace is the refining unit of argon oxygen decarburizing process, generally abbreviates the AOD stove as, and its profile and converter are approximate, body of heater be placed in one can before and after on the backing ring of tumbling, fixing by pin.Bottom side at stove is equipped with the spray gun that is blown into gas to the bath level direction, and the quantity of spray gun is generally 2～3 according to the tonnage of stove and different.Body of heater is built by laying bricks or stones with magnesia-calcium brick or magnesite chrome brick or rich konite brick, and movable furnace crown is built by laying bricks or stones with magnesite chrome brick or alumina-magnesia brick, also can water with heat resistance concrete, and refining is tapped through furnace crown after accomplishing.
AOD stove fire door tapping spout is a very crucial zone of AOD stove.The fire door tapping spout is exposed under the high temperature, and feeding, also having high temperature, chemical corrosion and mechanical wear when skimming and tapping, be the part of damaging the most easily in the body of heater, the life-span that therefore prolongs the fire door tapping spout is vital for the life-span that prolongs body of heater.
In the prior art, original AOD stove fire door tapping spout is " U " type structure, during the furnace lining knotting; Refractory materials is difficult to the jail and hangs over this zone, and during tapping, molten steel is prone to wash away furnace lining; Cause the tap hole scaling loss; And even near furnace wall scaling loss, the corrosion of tap hole, not only influence the ordinary production of AOD stove, also can lead to the bleed-out accident.
The utility model content
The utility model technical problem to be solved provide a kind of can make fire proof material of furnace lining can the jail hang on the tap hole, obviously improve AOD stove fire door tapping spout life-span, prolonged whole body of heater the argon oxygen decarburizing furnace fire door tapping spout device in work-ing life.
The technical scheme that solves the problems of the technologies described above is:
A kind of argon oxygen decarburizing furnace fire door tapping spout device; It is made up of fire door tapping spout, refractory materials, and its improvements are that said fire door tapping spout is "-" shape; Refractory materials is laid on the fire door tapping spout, and the last plane of refractory materials and the last plane of fire door flush.
Above-mentioned argon oxygen decarburizing furnace fire door tapping spout device, it also has the heat resisting iron plate, and the heat resisting iron plate is between fire door tapping spout and refractory materials, and the area of heat resisting iron plate and fire door tapping spout are complementary
The usefulness of the utility model is:
The utility model has improved the position and the shape of fire door tapping spout; " U " shape by prior art changes "-" shape into; Fire proof material of furnace lining can be hung on the tap hole in the jail; Molten steel does not directly contact fire door tapping spout and furnace shell, most desirably withstand temp, impact and chemical corrosion, therefore can obviously improve the life-span of AOD stove fire door tapping spout, also prolonged whole body of heater work-ing life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Mark is following among the figure: fire door tapping spout 1, refractory materials 2, heat resisting iron plate 3.
Embodiment
In the prior art, AOD stove fire door tapping spout is " U " type structure, and furnace lining when knotting, refractory materials is difficult to the jail and hangs over this zone, and during tapping, molten steel adds in the AOD stove through fire door tapping spout and refractory materials, and furnace charge is prone to come off, and washes away, seriously corroded.
The utility model has improved the position and the shape of fire door tapping spout 1; " U " shape by prior art changes "-" shape into; And between fire door tapping spout and refractory materials, increased heat resisting iron plate 3; Refractory materials 2 is laid on the heat resisting iron plate 3 of fire door tapping spout 1, and the last plane of refractory materials and the last plane of fire door flush.
Through such improvement fire proof material of furnace lining can be hung on the tap hole in the jail, the refractory materials of furnace charge and fire door tap hole is combined into a unified integral body.During tapping; Furnace charge and molten steel add in the AOD stove through the refractory materials on the heat resisting iron plate 3 on the fire door tapping spout 12; Molten steel does not directly contact fire door tapping spout and furnace shell; The furnace charge difficult drop-off has alleviated and has washed away and corrosion, therefore can obviously improve the life-span of AOD stove fire door tapping spout, also prolonged whole body of heater work-ing life.
The utility model has reached work-ing life of improving stove and the effect that reduces refractory consumption through adopting the device after improving, and worth relevant industries are applied.
