Abstract
The invention discloses a kind of graphite bars of steel wire infantees, it is mainly made up of graphite bars, high temperature cloth, steel wire and fire clay, and the outer peripheral face of graphite bars is enclosed with some floor height stupes, is wound with steel wire between every two layers adjacent high temperature cloth and is coated with fire clay.The present invention between each floor height stupe by increasing winding steel wire, high temperature cloth and the bond strength of fire clay can be improved, amount of contraction under the high temperature conditions is reduced, strengthens high temperature cloth performance such as resistance to erosion, anti-thermal shock in molten metal, effectively extends the service life of graphite bars.
Description
Technical field
The invention belongs to non-ferrous metal industry high temperature molten metal processing equipment technical field, specifically a kind of steel wire
The graphite bars of infantees.
Background technology
Because graphite has the characteristics that high temperature resistant, anti-thermal shock, elevated temperature strength are good, obtain extensively should in non-ferrous metal industry
With such as graphite bars in refinery by de-gassing equipment and pumping equipment.
Graphite bars directly contact when working with molten metal, cause graphite bars to fail because oxidation can occur for high temperature.In order to subtract
Slow oxidation process, increases the service life, and a kind of way is that one or more layers high temperature cloth, this mode are wrapped up on the graphite bars face of cylinder
It can slow down the oxidizing process of graphite bars to a certain extent, but be washed away and heat due to needing to bear stronger molten metal in molten metal
Concussion, high temperature cloth easily cracks and flakes off, so practical effect is not too much preferable.Therefore, it is badly in need of studying a kind of new construction
Graphite bars, to solve the problems, such as that high temperature cloth easily cracks and flakes off, extend the service life of graphite bars.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of graphite bars of steel wire infantees, can improve high temperature cloth with it is resistance to
The bond strength of chamotte, the amount of contraction of high temperature cloth under the high temperature conditions is reduced, strengthens high temperature cloth resistance to erosion, heat resistanceheat resistant in molten metal
The performances such as shake, effectively extend the service life of graphite bars.
The present invention solves above-mentioned technical problem with following technical scheme：
The graphite bars of steel wire infantees of the present invention, are mainly made up of, graphite bars graphite bars, high temperature cloth, steel wire and fire clay
Outer peripheral face be enclosed with some floor height stupes, be wound with steel wire between every two layers adjacent high temperature cloth and be coated with fire clay,
High temperature cloth and the bond strength of fire clay are improved by steel wire.
The outer peripheral face of the graphite bars is provided with screw thread, and high temperature cloth is coated on flank.
The steel wire is twist wound, and pitch is 1~10mm, and steel wire diameter is 0.1~3mm.
Thickness per floor height stupe is 0.5~3mm, and total number of plies of high temperature cloth is 2~5 layers.
The high temperature cloth is using high temperature cloth made of glass fabric or ceramic fiber cloth.
The pitch of the screw thread is 0.5~5mm, and the depth of thread is 0.5~5mm, form of thread be triangle or it is trapezoidal or
Zigzag or rectangle.
The smearing thickness of the fire clay is 0.5~2mm.
The graphite bars of steel wire infantees of the present invention, by increasing winding steel wire between each floor height stupe, improve high temperature cloth
With the bond strength of fire clay, high temperature amount of contraction under the high temperature conditions is reduced, enhancing high temperature cloth resistance to erosion, anti-in molten metal
The performances such as thermal shock, effectively extend the service life of graphite bars
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the graphite bars of steel wire infantees of the present invention；
Fig. 2 is the A portions enlarged diagram in Fig. 1；
Embodiment
Technical scheme is explained as follows below in conjunction with accompanying drawing：
As shown in Figure 1 and Figure 2,5 are threaded on the periphery face of cylinder of graphite bars 1, is wrapped up successively on flank some
Floor height stupe 2, winding steel wire 3 between every two layers adjacent high temperature cloth 2, and smear fire clay 4.
High temperature cloth 2 can prevent graphite bars from directly being contacted with molten metal or air, effectively alleviate the oxidizing process of graphite bars.
Fire clay 4 can make adjacent high-temperature cloth 2 be brought into close contact shaping, increase the rigidity of infantees layer.Between every two layers adjacent high temperature cloth 2
Winding steel wire 3, forms it into the structure similar to " reinforced concrete ", and the combination that can effectively improve high temperature cloth 2 and fire clay 4 is strong
Degree, the amount of contraction of high temperature cloth 2 under the high temperature conditions is reduced, strengthens high temperature cloth performance such as resistance to erosion, anti-thermal shock in molten metal.
Tested by application, using the service life of graphite bars of the invention up to common infantees graphite bars service life
3~6 times.
In the present invention, steel wire 3 can line uniform winding, pitch be helically 1~10mm.Steel wire 3 can use 310,310S,
316th, the corrosion-and high-temp-resistant stainless steel such as 316L material makes, its a diameter of 0.1~3mm.
In the present invention, the thickness per floor height stupe 2 is 0.5~3mm, and the number of plies is 2~5.The material of high temperature cloth 2 can use glass
The corrosion-and high-temp-resistant such as glass fiber cloth, ceramic fiber cloth cloth makes.
In the present invention, the pitch of screw thread 5 is 0.5~5mm, and the depth of thread is 0.5~5mm, form of thread be triangle,
Trapezoidal, zigzag, rectangle etc..
In the present invention, the fire clay 3 that uses for certain viscosity and resistant to elevated temperatures mud, smearing thickness is 0.5~
2mm。
