Description

Molten iron pre-processes low thermal stress desulfuring spray gun
Technical field
The utility model belongs to desulfurizing iron apparatus field, more particularly to a kind of molten iron pretreatment low thermal stress desulfuring spray gun.
Background technology
External desulfurization of hot metal injection technology is developed so far from the 50's of 20th century and is widely used.The technology A variety of desulfurizing agents can be preferably adapted to, the desulphurizing ability of desulfurizing agent has been given full play to, excellent desulfurized effect is reached.
Spray gun is the important component of blowing desulfurization equipment, and its condition of work is severe, in 1350 °~1400 ° of molten iron In frequently bear thermal shock.The injection tube of spray gun and gun body refractory material physical parameter difference are excessive, at high operating temperatures, because not The thermal stress that synthermal gradient is caused often causes body of spray gun rifle to crack or even occur the phenomenons such as perforation.Blowing desulfurization skill The gun body short life of art generally existing, the problems such as cost is high fails to solve always.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provide a kind of simple in construction, gun body long lifespan, into This cheap molten iron pretreatment low thermal stress desulfuring spray gun.
To reach above-mentioned purpose, what the utility model was realized in.
Molten iron pre-processes low thermal stress desulfuring spray gun, including core jet pipe, pillar, reinforced pipe, skeleton and located at reinforced pipe Outer refractory masses;The core jet pipe is set in pillar;The protective pipe sleeve is loaded in reinforced pipe;The skeleton is placed in resistance to It is fixedly connected in fiery material layer and with the outer wall of reinforced pipe;The skeleton is using transverse annular muscle and the net of longitudinal rib cross-distribution Grating texture;Claws of a hawk shape anchoring piece is fixed with the skeleton;Heat-barrier material is provided between the reinforced pipe and pillar Layer;Latticed cylindrical sleeve is longitudinally provided with the skeleton;The latticed cylindrical sleeve is fixedly connected with skeleton;Described Fixed pedestal is provided between core jet pipe and pillar bottom.
As a kind of preferred scheme, the utility model is provided with heat radiation transition zone in the outer wall of the insulation material layer.
Further, the cavity that the utility model is formed between the core jet pipe and pillar is built-in with stress buffer Agent.
The utility model lance body structure is simple, from structure design angle, passes through transverse annular muscle and longitudinal rib cross-distribution Fenestral fabric skeleton, reinforced pipe, latticed cylindrical sleeve, claws of a hawk shape anchoring piece, heat radiation transition zone and stress buffer agent The overall thermal stress of gun body and the spray gun perforated phenomenon occurred therefrom are reduced Deng design, the use longevity of desulfuring spray gun is improved Life.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is overall structure diagram of the present utility model.
In figure:1st, core jet pipe;2nd, pillar;4th, refractory masses;5th, skeleton;6th, claws of a hawk shape anchoring piece;7th, it is hot Overradiation layer;8th, reinforced pipe;9th, latticed cylindrical sleeve;10th, insulation material layer;11;Fixed pedestal.
Embodiment
As illustrated, molten iron pre-processes low thermal stress desulfuring spray gun, including core jet pipe 1, pillar 2, reinforced pipe 8, skeleton 5 And the refractory masses 4 outside reinforced pipe 8;The core jet pipe 1 is set in pillar 2;The pillar 2 is set in reinforced pipe In 8;The skeleton 5 is placed in refractory masses 4 and is fixedly connected with the outer wall of reinforced pipe 8;The skeleton 5 uses transverse annular Muscle and the fenestral fabric of longitudinal rib cross-distribution;Claws of a hawk shape anchoring piece 6 is fixed with the skeleton 5;Strengthen described Insulation material layer 10 is provided between pipe 8 and pillar 2;Latticed cylindrical sleeve 9 is longitudinally provided with the skeleton 5;The grid Shape cylindrical sleeve is fixedly connected with skeleton 5;Fixed pedestal 11 is provided between the core jet pipe 1 and the bottom of pillar 2.
The utility model is provided with heat radiation transition zone 7 in the outer wall of the insulation material layer 10.The utility model is described The cavity formed between core jet pipe 1 and pillar 2 is built-in with stress buffer agent.The agent of the utility model stress buffer can be fine using carbon Tie up material.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
