The specific embodiment
Below in conjunction with Figure of description, the present invention is explained further details.
Like Fig. 3,4, shown in 5, a kind of pours lining of the present invention is used ceramic anchor studs, comprises base nail 1 and a pair of nail body, and said base nail 1 is " V " font.Like Fig. 1, shown in 2, said a pair of nail body is fixedly connected with the two ends of base nail 1 respectively and is " V " font.
Nail body according to the invention comprises spike 3 or short nail 2, adopts Al
2O
3Content is greater than 90%, ZrO
2Content forms greater than 3.7% toughening type composite ceramic material sintering.The cross section of nail body is circular, and the basic geometry of employing is cylindrical.Be rigidity that strengthens the nail body and the adhesive force that improves lining, take following design:
1, circumferentially 90 ° 4 ribs is set altogether in the interval at it;
2, the part increases slightly in the middle of the spike 3;
3, the major part design is adopted in the end.
Because of this material is a fragile material, so fillet or chamfered transition are all adopted in the inside and outside turning of nail on the body, produce stress and concentrate and destroy to avoid following closely body, also make lining avoid sharp corner at the nail body to crack and along exhibition and destroy simultaneously.
Thickness according to lining is different, and the length of nail body also adopts different specifications, or adopts the form of length collocation.Liner thickness generally is the boundary with 100mm, is thick lining greater than 100mm, is thin lining smaller or equal to 100mm.Ceramic anchor studs according to the 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 arbitrarily, but can cause kind too many like this.Through practical experience for many years, these two angles use more flexible, and adaptability is stronger, so just be fixed on it on these two angles.
As shown in Figure 1, when being used for liner thickness, adopt a spike 3 and short nail 2 combinations greater than the operating mode of 100mm, angle A is 60 °.The two support pin bodies that adopt that one is long and the other is short, the one, when being used for the double-deck pouring material, be earlier fixing one deck; The 2nd, when being used for thicker lining,, make lining layering at this level easily if all nails are all equally long, form tangent plane, finally come off easily.During use, base nail 1 is welded on the equipment inwall, 2 pottery nail bodies are linked together by screw thread and base nail 1.Fixing weak point is followed closely 2 length, selects the length of spike 1 again according to the thickness of lining.
As shown in Figure 2, when being used for liner thickness, adopt the combinations of two short nails 2 smaller or equal to the operating mode of 100mm, angle A is 90 °.When liner thickness was thin, therefore the nail point spacing of two nail bodies was used than 90 ° of large angles by angle and so not big with the extension of thickness.Thin lining is difficult for layering and comes off, therefore with two isometric short nails 2.Same base nail 1 is welded on the equipment inwall and based on the thickness of lining, adjust two short length of 2 of following closely.
Relatively easy fixation is on the furnace wall in order to make anchor studs, and base nail 1 adopts metal material, and a side is welded with the equipment wallboard mutually, and opposite side is connected with ceramic anchoring ailing body with the form of screw thread.Making the concrete material of base nail and also decided by the temperature of service condition, is carbon steel generally speaking.
