Abstract
A special bolt for fixing a saddle of a steel charge machine of a heating furnace structurally comprises a bolt body and nuts, the bolt body comprises heads and a threaded rod, the threaded rod is provided with two annular grooves, a layer of polycrystalline mullite fibrofelt is fixed in each annular groove by means of adhesion, and the external diameter of the polycrystalline mullite fibrofelt is 1mm larger than the diameter of the threaded rod. The special bolt for fixing the saddle of the steel charge machine of the heating furnace has the advantages that a columnar rod body between the two annular grooves plays a role in positioning, the polycrystalline mullite fibrofelt is used for preventing oxide scales and in-furnace low-melting-point articles from intruding into the gaps between the bolt and bolt holes, and a non-adhesive isolation layer existing between the bolt and the bolt holes is guaranteed, so that bolt detachment is facilitated; the defects that the fixed bolt is difficult to detach during saddle replacement due to proneness to adhesion between the bolt and the bolt holes and the like in the prior art are overcome.
Description
Technical field
The present invention relates to heating furnace steel loading machine saddle technique for fixing field, specifically a kind of heating furnace steel loading machine saddle
Fixing special bolt.
Background technology
In plate belt hot rolling factory, heating furnace steel loading machine saddle is bolted on steel loading bar, by steel loading bar, slab is delivered to
In stove, due to the intrusion melting thing low in iron scale and stove in work, make to be full of between bolt and bolt hole and be sintered together
Low in iron scale and stove melt thing, so that bolt is sticked together with bolt hole, need to change and bolt often occurs during saddle be difficult to tear open
Unload, dismounting and change again after sometimes needing with carbon arc air gouging, bolt to be melted, the repair and replacement time is long, thus impact is normal using.
Content of the invention
Present invention aims to the deficiencies in the prior art, a kind of heating furnace steel loading machine saddle is provided to fix special spiral shell
Bolt, this bolt is applied to the fixation of heating furnace steel loading machine saddle, simultaneously facilitates dismounting.
The present invention solves its technical problem and is adopted the technical scheme that: a kind of heating furnace steel loading machine saddle fixes special spiral shell
Bolt, including bolt body and nut, described bolt body includes head and screw rod, and described nut is matched with screw rod, institute
The screw rod stated is provided with two annular grooves, and two annular grooves are respectively positioned at upper and lower and two annular grooves of screw rod
Between between be separated with one section of column shaft, be provided with a floor height temperature fiber felt in described annular groove.
Further technical scheme is: described high temperature fiber felt is fixed on described annular groove by way of gluing
Interior.
Further technical scheme is: the external diameter of described high temperature fiber felt is more than described screw diameter 1mm.
Further technical scheme is: described high temperature fiber felt is polycrystalline mullite fibre felt.
Compared with prior art, the method have the advantages that be applied to heating furnace steel loading machine saddle fixation and
Positioning, the column shaft between two annular grooves plays positioning action, and polycrystalline mullite fibre felt stops iron scale and stove
Interior low melt in the space that thing invades between bolt and bolt hole, ensure to have between bolt and bolt hole simultaneously one layer NA
Sealing coat, is easy to the dismounting of bolt.Overcome bolt and bolt hole in original technology to be easily sticked together, lead to saddle to be changed
During, the defect such as fixing bolt is difficult to dismantle.
Brief description
Fig. 1 is the structural representation of the embodiment of the present invention；
Fig. 2 is the structural representation of embodiment of the present invention bolt body part；
Fig. 3 is the structural representation after the present invention is assembled with heating furnace steel loading machine saddle.
In figure: 1 bolt body, 11 column shafts, 12 annular grooves, 2 high temperature fiber felts, 3 nuts, 4 saddles, 5 steel loading bars.
Specific embodiment
With reference to Figure of description and specific embodiment, the invention will be further described:
As shown in Figure 1.A kind of heating furnace steel loading machine saddle of the present invention fixes special bolt, including bolt body 1 and spiral shell
Female 3, described bolt body 1 includes head and screw rod, and described nut 3 is matched with screw rod, and described screw rod is provided with two
Individual annular groove 12, two annular grooves 12 are separated between being located at respectively between the upper and lower of screw rod and two annular grooves 12
One section of column shaft 11, is provided with a floor height temperature fiber felt 2 in described annular groove 12.
As shown in Fig. 2 column shaft 11 is a diameter of φ 1 of screw rod, screw rod is provided with the section diameter of annular recess 12
For φ 2.
Described high temperature fiber felt 2 is fixed in described annular groove 12 by way of gluing.
The external diameter of described high temperature fiber felt 2 is more than described screw diameter 1mm.
Described high temperature fiber felt 2 is polycrystalline mullite fibre felt.
For ease of the understanding of the present invention, the invention will be further described to use process with reference to it:
As shown in figure 3, column shaft 11 part is located at steel loading bar 5 and the faying face of saddle 4, play the role of positioning.Use glue
Polycrystalline mullite fibre felt is bonded at two sections of annular groove 12 parts by water, and 1 saddle 4 of bolt body is fixed on steel loading bar 5,
One section of polycrystalline mullite fibre felt on screw rod top seals the space between the bolt hole on saddle 4 top and bolt body 1, with
Another section of polycrystalline mullite fibre felt of sample screw rod bottom is the space between the bolt hole of steel loading bar 5 bottom and bolt body 1
Seal, prevent in iron scale and stove low melt thing invade, simultaneously ensure card bolt and bolt hole between have one layer NA every
Absciss layer is polycrystalline mullite fibre felt, is easy to Bolt dismantling.
The foregoing is only presently preferred embodiments of the present invention, be not the whole embodiments of the present invention, not in order to limit
The present invention processed, all any modification, equivalent substitution and improvement within the spirit and principles in the present invention, made etc., should be included in
Within protection scope of the present invention.
In addition to technical characteristic described in description, remaining technical characteristic is technology known to those skilled in the art, in order to prominent
Go out the innovative characteristicses of the present invention, will not be described here.
