Abstract
The utility model discloses a desulphurization gun which comprises a gun core (1) welded by a steel structure, a protective tube (2) wrapping the gun core (1) and a refractory material layer (3) positioned on the front part of the protective tube (2), wherein lifting lugs (4) are arranged at the rear end of the protective tube (2), and are connected with a chain (5). The desulphurization gun is characterized in that the front end of the gun core (1) extends from the outer side of the protective tube (2), and is positioned in the refractory material layer (3); the refractory material layer (3) is made of a high-aluminum castable. According to the desulphurization gun, the gun core welded by the steel structure and the refractory material layer made of the high-aluminum castable form a main part of the desulphurization gun, and the high-aluminum castable is a high-quality refractory material obtained by combining a main body electro-fused mullite and submicron powder, so that the desulphurization gun has good using effects, and is long in service life, stable in overall structure, convenient to use and suitable for popularization and use.
Description
Technical field
The utility model relates to a kind of desulfurization rifle of long service life.
Background technology
Desulfurization rifle is applied to the external refining of molten iron, is the desulfurization of molten iron, the major parts of dephosphorization processing apparatus.The principle of work of desulfurization rifle: be to spray in molten iron by spray gun centre hole with metal magnesium powder and calcium oxide micro mist, react generation volatile matter and generate vitriol, phosphoric acid salt slag with the detrimental impurity p and s in molten iron, and the light specific gravity of slag very easily floats to the surface of molten iron, be conducive to remove.By the blowing of 5 to 15 minutes, make molten iron reach desirable composition.Existing desulfurization rifle, due to the problem of structure and refractory masses existence, will soon damage after coming into operation, and has had a strong impact on rhythm of production and work-ing life.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, and a kind of desulfurization rifle of long service life is provided.
The purpose of this utility model solves by the following technical programs:
A kind of desulfurization rifle, comprise the protecting tube of rifle core that during welding for steel structure forms, parcel rifle core and be positioned at the refractory masses of protecting tube front portion, the rear end of protecting tube is provided with hanger and hanger is connected with chain, the front end that it is characterized in that described rifle core stretches out the outside of protecting tube and is positioned at refractory masses, and refractory masses adopts high alumina castable to make.
Between described rifle core and protecting tube, be provided with protection inner tube, between protection inner tube, rifle core, protecting tube three, be all provided with gap.
The rear end of described refractory masses seals on the outer wall that is fixed on protecting tube by intermediate connection tube.
In described refractory masses, be provided with one end and be fixed on the anchoring piece on protecting tube outer wall, anchoring piece is axially uniformly distributed along protecting tube.
The utility model has the following advantages compared to existing technology:
The utility model adopts during welding for steel structure the rifle core forming and the refractory masses that adopts high alumina castable to make to form the major portion of desulfurization rifle, wherein high alumina castable is take electrofused mullite as main body and adopt the high-quality refractory material of super-fine powder combination, good and the long service life of result of use, one-piece construction is stable and easy to use, suitable promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-rifle core; 2-protecting tube; 3-refractory masses; 4-hanger; 5-chain; 6-protection inner tube; 7-intermediate connection tube; 8-anchoring piece.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of desulfurization rifle, comprise the protecting tube 2 of rifle core 1 that during welding for steel structure forms, parcel rifle core 1 and be positioned at the refractory masses 3 of protecting tube 2 front portions, be all provided with gap being provided with between rifle core 1 and protecting tube 2 between protection inner tube 6 and protection inner tube 6, rifle core 1, protecting tube 2 threes; The rear end of protecting tube 2 is provided with hanger 4 and hanger 4 is connected with chain 5, front end at rifle core 1 stretches out the outside of protecting tube 2 and is positioned at refractory masses 3, refractory masses 3 adopts high alumina castable to make, the rear end of refractory masses 3 is fixed on the outer wall of protecting tube 2 by intermediate connection tube 7 sealings in addition, in refractory masses 3, be provided with one end and be fixed on the anchoring piece 8 on protecting tube 2 outer walls, anchoring piece 8 is axially uniformly distributed along protecting tube 2.
The utility model adopts during welding for steel structure the rifle core 1 forming and the refractory masses 2 that adopts high alumina castable to make to form the major portion of desulfurization rifles, wherein high alumina castable is take electrofused mullite as main body and adopt the high-quality refractory material of super-fine powder combination, good and the long service life of result of use, one-piece construction is stable and easy to use, suitable promoting the use of.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
