Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in further details.
As shown in Fig. 3,4,5, the ceramic anchor studs of a kind of castable lining of the present invention, comprises base nail 1 and a pair rivet nut, and described base nail 1 is in " V " font.As shown in Figure 1, 2, the two ends that described a pair rivet nut follows closely 1 respectively with base are fixedly connected with and are " V " font.
Rivet nut of the present invention comprises spike 3 or short nail 2, adopts Al
2o
3content is greater than 90%, ZrO
2content be greater than 3.7% toughening type composite ceramic material sintering form.The cross section of rivet nut is circular, and the basic geometry of employing is cylindrical.For strengthening the rigidity of rivet nut and improving the adhesive force of lining, take following design:
1,4 ribs are set altogether at its 90 °, circumferential interval;
2, in the middle of spike 3, local increases thick;
3, end adopts major part design.
Because this material is fragile material, so the inside and outside turning in rivet nut all adopts fillet or chamfered transition, destroy to avoid rivet nut generation stress to concentrate, also make lining avoid cracking at the sharp corner of rivet nut and destroying along exhibition simultaneously.
Different according to the thickness of lining, the length of rivet nut also adopts different specifications, or adopts the form of length collocation.Liner thickness is generally boundary with 100mm, and being greater than 100mm is thick lining, and being less than or equal to 100mm is thin lining.Ceramic anchor studs of the present invention is under the operating mode of thick, thin two kinds of different linings, and the subtended angle A of base nail 1 is divided into 60 ° and 90 ° two kinds.In theory, this angle is as required can be arbitrary, but kind can be caused so too many.Through practical experience for many years, these two angles use relatively more flexible, and adaptability is comparatively strong, so just it has been fixed in these two angles.
As shown in Figure 1, when being greater than the operating mode of 100mm for liner thickness, adopt a spike 3 and a short nail 2 to combine, angle A is 60 °.Adopt one is long and the other is short two rivet nuts, one when being for double-deck pouring material, first will fix one deck; Two when being for thicker lining, if all nails are all equally long, easily makes lining layering at this level, forms tangent plane, finally easily come off.During use, be welded on equipment inner wall by base nail 1,2 ceramic rivet nuts are followed closely 1 by screw thread and base and are linked together.The length of fixing short nail 2, selects the length of spike 1 again according to the thickness of lining.
As shown in Figure 2, when being less than or equal to the operating mode of 100mm for liner thickness, adopt the combination of two short nails 2, angle A is 90 °.When liner thickness is thinner, the extension of the nail tip spacing of two rivet nuts angularly and with thickness is so not large, therefore uses comparatively large angle 90 °.Thinner lining not easily layering comes off, therefore with isometric two short nails 2.Same base nail 1 to be welded on equipment inner wall and according to the thickness of lining, to adjust the length of two short nails 2.
For making anchor studs ratio be easier to be fixed on furnace wall, base nail 1 adopts metal material, and side is welded mutually with equipment wallboard, and opposite side is connected with ceramic anchor studs rivet nut with the form of screw thread.The concrete material making base nail is also determined by the temperature of service condition, is generally carbon steel.
Above-described detailed description of the invention; further detailed description has been carried out to object of the present invention, technical scheme and beneficial effect; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
