Abstract
The utility model discloses a fastener of a high temperature furnace, which has good mechanical properties and long service life. The fastener comprises a screw (1), a bolt (2), a stud (3) and a nut (4). The utility model is characterized in that the screw (1), the bolt (2), the stud (3) and the nut (4) are processed by carbon/carbon composite materials. Because the inner of the carbon fiber composite materials has a quasi-three-dimensional structure, the processed fastener has excellent high specific strength, small heat expansion coefficient and the performance of resistance to thermal shock and no deformation and cracking. The service life is greatly improved, and the life after trial use can reach more than one year.
Description
Technical field:
The utility model relates to a kind of high temperature furnace employed part under protective atmosphere or vacuum condition, specifically a kind of high temperature furnace used securing member.
Background technology:
At present, the calandria of pyrometallurgy stove generally is made up of electrode, contiguous block and securing member etc., its material is made by graphite, exist during use because of graphite screw poor mechanical property, often fracture and losing efficacy causes calandria to fall apart, and causes to stop production or accident, have a strong impact on ordinary production, the useful life that has is two ten days only; In the polycrystalline furnace crucible tray, formed by graphite cake and graphite screw, the graphite screw often ruptures because of being subjected to the thermal stress effect, in the only several days useful life that has, production cost is increased.Carbon fiber composite is to be combined into prefabricated component by charcoal fleece and charcoal cloth through lamination, again by making carbon/carbon composite after chemical vapour deposition (CVD) density and/or the dipping density, have high specific strength, high ratio modulus, high temperature resistant, anti-ablation, little, the anti-rapid heat cycle of thermal coefficient of expansion and indeformable premium properties such as do not ftracture, be adapted to the high temperature field especially, now having become or will progressively become one of the important foundation material in fields such as Aero-Space, metallurgy, new forms of energy, is the ideal substitute that substitutes the graphite securing member in the hot environment.
Summary of the invention:
The purpose of this utility model provides that a kind of mechanical property is good, the high temperature furnace used securing member of long service life.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of high temperature furnace used securing member, and it comprises screw, bolt, double-screw bolt and nut, described screw, bolt, double-screw bolt and nut are processed into by carbon/carbon composite.
The utility model is fixed for ease of using spanner, and the spiral shell head on screw, the bolt is square toes.
Spiral shell head on the utility model screw, the bolt is round end or square toes or countersunk head, fixes for ease of adopting bottle opener, is equipped with flat recess or cross recess on it.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, because carbon fiber composite inside has accurate three-dimensional structure, the securing member of being processed into, has the excellent little and anti-rapid heat cycle of high specific strength, thermal coefficient of expansion and indeformable indehiscent performance, make it to be not easy to break under the effect of external force or in the operational environment of rapid heat cycle, significantly improve its useful life, can reach more than 1 year through the life-span on probation.

Fig. 2 is the structural representation of the utility model bolt 2, nut 4;
Fig. 3 is the structural representation of the utility model screw 1.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 1, Fig. 2, Fig. 3 as can be known, a kind of high temperature furnace used securing member, it comprises screw 1, bolt 2, double-screw bolt 3 and nut 4, described screw 1, bolt 2, double-screw bolt 3 and nut 4 are processed into by carbon/carbon composite.
Spiral shell head 5 on the utility model screw 1, the bolt 2 is round end or square toes or countersunk head, is equipped with flat recess or cross recess (the spiral shell head 5 on the present embodiment bolt 2 is round end, which is provided with flat recess, and the spiral shell head 5 on the screw 1 is a countersunk head, which is provided with cross recess) on it.
The carbon fiber reinforced carbon based composites that described carbon/carbon composite is made up of the pure carbon element, its moulding is combined into prefabricated component by charcoal fleece and charcoal cloth through lamination, again by making after chemical vapour deposition (CVD) density and the dipping density.
The utility model uses screw 1, and two sheet materials, bar or webs are coupled together, and its screw thread specification generally is no more than M26; Bolt 2 links together several sheet materials, bar or web by cooperating and connected piece can be clamped with nut 4, and its screw thread specification generally is no more than M56; Double-screw bolt 3 two and nut 4 are used, and lean on the nut 4 at two or add clamping plate connected piece is clamped, and its screw thread specification is generally more than M6.
