Technical field
The utility model relates to the steel-making converter vaporising device, more particularly, relates to the vaporization cooling petticoat pipe that is used for steel-making converter.
Background technology
Steel-making converter OG system vaporization cooling petticoat pipe is the Cylinder shape constructional element that is connected into by the weldless steel tube weld all around, is used to collect, the equipment of transporting and cooled flue gas, is divided into fixedly petticoat pipe and movable gas hood two portions.Water coolant in the vaporization cooling petticoat pipe pipe absorbs the heat of the high-temperature flue gas that flows through and vaporizes, produced the mixture of steam and water, carbonated drink is separated after upcast enters drum, and the water after the separation is sent into vaporization cooling petticoat pipe through downtake under the effect of water circulating pump, continued cooling effect.
Vaporization cooling petticoat pipe is subjected to inhomogeneous erosive wear, oxidation and the corrosion of high temperature and high speed ash-laden gas for a long time because the operation condition condition is very abominable, and being heated faces the wall and meditates is worn very soon and corrodes the rapid attenuate of steel pipe walls.Have only 12 months the work-ing life of vaporization cooling petticoat pipe under the effect of above-mentioned factor.
New vaporization cooling petticoat pipe use just occurred corrosion in two, three months and becomes the book phenomenon, begins to leak, and must carry out soldering to it in order not influence production.The employee need enter soldering in the petticoat pipe when soldering, and its potential safety hazard is big, often mistakes, and has caused very big influence to production.
The utility model content
In view of this, the utility model is provided for the vaporization cooling petticoat pipe of steel-making converter, to prolong the work-ing life of petticoat pipe.
For achieving the above object, the utility model provides following technical scheme:
A kind of vaporization cooling petticoat pipe that is used for steel-making converter comprises the petticoat pipe main body, and described petticoat pipe main body comprises inner and outer wall, and described inwall is provided with anti-oxidant wearing layer.
Preferably, at the above-mentioned vaporization cooling petticoat pipe that is used for steel-making converter, described anti-oxidant wearing layer is the aluminum oxide wearing layer.
Preferably, at the above-mentioned vaporization cooling petticoat pipe that is used for steel-making converter, be enclosed with the metal separation net on the described outer wall.
From technique scheme as can be seen, passing through among the utility model embodiment is provided with on the inwall of petticoat pipe main body that inhomogeneous that anti-oxidant wearing layer can prevent the high temperature and high speed ash-laden gas effectively washed away, oxidation and corrosion, thereby can prolong the work-ing life of the vaporization cooling petticoat pipe that is used for steel-making converter.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The vaporization cooling petticoat pipe structural representation that is used for steel-making converter that Fig. 1 provides for the utility model embodiment;
The structural representation of the petticoat pipe main body that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of vaporization cooling petticoat pipe that is used for steel-making converter, to prolong the work-ing life of vaporization cooling petticoat pipe.Vaporization cooling petticoat pipe is the equipment of collection, cooling, supplied flue gases, dust, comprise movable gas hood 12 and fixing petticoat pipe 11, as shown in Figure 1, wherein, movable gas hood 12 is enclosed within fixedly petticoat pipe 11 outsides can lifting, drop to the converter mouth top during converter 13 blowing, the one-time dedusting facility is collected, cooled off, is transported to converter gas and dust by vaporization cooling petticoat pipe, are drawn onto gas recovering device by spray water cooling back by the coal-gas recovering blower fan and reclaim.
In the utility model embodiment, prolong the work-ing life that petticoat pipe is cooled off in vaporization by wear resisting property and the antioxidant property that strengthens petticoat pipe.
As shown in Figure 2, vaporization cooling petticoat pipe is the cylindrical member that is welded by weldless steel tube, in the utility model embodiment, be called petticoat pipe main body 10 for this cylindrical member, the inwall 102 of the petticoat pipe main body 10 of cylindrical member forms the passage that holds flue gas, the outer wall 101 of petticoat pipe main body 10 contacts with the external world, concrete, the inwall 102 of petticoat pipe main body 10 is provided with anti-oxidant wearing layer 103 among the utility model embodiment, and this anti-oxidant wearing layer 103 can be metal level or the metal oxide layer with antioxidant property.Passing through among the utility model embodiment is provided with on the inwall 102 of petticoat pipe main body 10 that inhomogeneous that anti-oxidant wearing layer 103 can prevent the high temperature and high speed ash-laden gas effectively washed away, oxidation and corrosion, thereby can prolong the work-ing life of the vaporization cooling petticoat pipe that is used for steel-making converter.
When producing, adopt following technology effectively to handle:
A, surface preparation: with the inwall 102 row sandblast operations of sand-blast device to vaporization cooling petticoat pipe, its effect is, at first, can remove by the various foreign material on spray surface, particularly grease, dirt, oxide skin, iron rust, paint coating etc., the surface shows even metal gloss, is beneficial to the bonding absorption of melted powder and matrix surface, reaches the effect that purifies the surface.Secondly, make surface coarsening, make the spraying mask that certain roughness be arranged, improve the bonding adsorptive power of bonding surface.At last, can activating surface, sandblast makes by sprayed surface and forms activation capacity, is beneficial to increase spraying particle and matrix surface adsorptive power, the metallurgical binding ability of raising sprayed particle and matrix.
