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

A kind of oven dress steel machine saddle fixes special bolt

Technical field

The present invention relates to oven dress steel machine saddle technique for fixing field, specifically a kind of oven dress steel machine saddle fixes special bolt.

Background technique

In plate belt hot rolling factory, oven dress steel machine saddle is bolted on dress steel pole, by dress steel pole, slab is delivered in stove, due to intrusion of melting thing low in iron scale and stove in work, make to be full of between bolt and bolt hole and lowly in the iron scale and stove that are sintered together melt thing, bolt and bolt hole are sticked together, when need change saddle, often occur that bolt is difficult to dismounting, sometimes need with carbon arc air gouging dismounting and change again after bolt fusing, the repair and replacement time is long, thus the normal use of impact.

Summary of the invention

The object of the invention is to for the deficiencies in the prior art, provide a kind of oven to fill steel machine saddle and fix special bolt, this bolt is applicable to the fixing of oven dress steel machine saddle, is convenient to dismounting simultaneously.

The present invention solves the technological scheme that its technical problem takes: a kind of oven dress steel machine saddle fixes special bolt, comprise bolt body and nut, described bolt body comprises head and screw rod, described nut matches with screw rod, described screw rod is provided with two annular grooves, two annular grooves lay respectively at screw rod upper and lower and between two annular grooves between be separated with one section of column shaft, be provided with one deck high temperature fiber felt in described annular groove.

Further technological scheme is: described high temperature fiber felt is fixed in described annular groove by gluing mode.

Further technological scheme is: the external diameter of described high temperature fiber felt is greater than described screw diameter 1mm.

Further technological scheme is: described high temperature fiber felt is polycrystalline mullite fibre felt.

Compared with prior art, the present invention has following beneficial effect: be applicable to fixing and positioning of oven dress steel machine saddle, column shaft between two annular grooves plays positioning action, polycrystalline mullite fibre felt stops and lowly in iron scale and stove melts in space that thing invades between bolt and bolt hole, ensure there is the NA separation layer of one deck between bolt and bolt hole simultaneously, be convenient to the dismounting of bolt.Overcome bolt and bolt hole in original technology to be easily sticked together, cause in saddle Renewal process, fixing bolt is difficult to the defects such as dismounting.

Accompanying drawing explanation

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 be the present invention and oven fill steel machine saddle assemble after structural representation.

In figure: 1 bolt body, 11 column shafts, 12 annular grooves, 2 high temperature fiber felts, 3 nuts, 4 saddles, 5 dress steel poles.

Embodiment

Below in conjunction with Figure of description and specific embodiment, the invention will be further described:

As shown in Figure 1.A kind of oven dress steel machine saddle of the present invention fixes special bolt, comprise bolt body 1 and nut 3, described bolt body 1 comprises head and screw rod, described nut 3 matches with screw rod, described screw rod is provided with two annular grooves 12, two annular grooves 12 lay respectively at screw rod upper and lower and between two annular grooves 12 between be separated with one section of column shaft 11, be provided with one deck high temperature fiber felt 2 in described annular groove 12.

As shown in Figure 2, the column shaft 11 i.e. diameter of screw rod is φ 1, and the section diameter that screw rod is provided with annular recess 12 is φ 2.

Described high temperature fiber felt 2 is fixed in described annular groove 12 by gluing mode.

The external diameter of described high temperature fiber felt 2 is greater 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, below in conjunction with its using process, the invention will be further described:

As shown in Figure 3, column shaft 11 part is positioned at dress steel pole 5 and the junction plane place of saddle 4, plays the role of positioning.With glue, polycrystalline mullite fibre felt is bonded at two sections of annular groove 12 part places, bolt body 1 is fixed on saddle 4 on dress steel pole 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, another section of polycrystalline mullite fibre felt of same screw rod bottom seals the space between the bolt hole of dress steel pole 5 bottom and bolt body 1, prevent the low thing that melts in iron scale and stove from invading, ensure have the NA separation layer of one deck and polycrystalline mullite fibre felt between card bolt and bolt hole simultaneously, be convenient to Bolt dismantling.

The foregoing is only preferred embodiment of the present invention; be not whole embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.

Except technical characteristics described in specification, all the other technical characteristicss are those skilled in the art's known technology, in order to outstanding innovative characteristics of the present invention, do not repeat them here.
