Abstract
The invention discloses a reduced-pressure anticreeping separation wall of a furnace body, which is made of firebrick; an axle wire of the separation wall is provided with a plurality of vertical air holes in equivalent interval which are separately distributed in star-shaped manner along the unilateral opened expansion gaps at two sides of the separation wall, and the expansion gaps at the two sides are not overlapped. The separation wall in the technical proposal of the invention is provided with non-communicated expansion gaps at two sides thereof so that coke powder at the two sides of the furnace body can not be communicated and the root cause of the leakage is cut off; on the other hand, the air holes in the technical proposal of the invention can cause the heat on the separation wall transmitted by the air holes to be quickly emitted so that the pressure on the wall caused by expansion and contraction is reduced and the service life of the wall is prolonged.
Description
Technical field
The present invention relates to a kind of reduced-pressure anticreeping separation wall of furnace body, especially a kind of reduced-pressure anticreeping separation wall of furnace body that is used for graphitizing furnace.
Background technology
Graphite electrode is widely used in metallurgy industry, calculates one ton of steel of every refining according to industry and need consume the 150kg graphite electrode, and therefore, graphite electrode belongs to the running stores of metallurgy industry, and consumption is very big, and the electric conductivity of electrode directly influences metallurgical efficient.The most common graphite electrode processing method is to feed big electric current generation high temperature the former base of graphite is carried out graphitization in horizontal electric resistance furnace at present, current processing method is the former base series connection of a plurality of graphite to be couched be placed in the resistance furnace, on the former base of graphite, cover thick coke powder heat-insulation layer, the body of heater divider wall of prior art is owing to will overcome the body of wall expanded by heating, meet the destruction of cold contraction to body of wall, usually adopt on body of wall and stay an expansion joint every a segment distance, this expansion joint can be ventilated the body of wall both sides, the existence at this expansion joint, make the coke powder intercommunication of divider wall both sides, after adding electric current, electric current makes both sides body of heater electric leakage by coke powder, consume a large amount of electric energy, and make graphite former base graphitization in two ends insufficient, influenced the electrical efficiency of graphite electrode.
Summary of the invention
Technical problem to be solved by this invention is the technical problem of divider wall electric leakage.
In order to solve the problems of the technologies described above, the invention provides a kind of reduced-pressure anticreeping separation wall of furnace body, this divider wall is to be made of refractory brick, equidistant some vertical pores that distribute on the axis of this divider wall, and some vertical pores are to unidirectional expansion joint of opening, divider wall both sides respectively
Shape distributes, and the expansion joint, both sides does not overlap mutually.
As the preferred technical solution of the present invention, described expansion joint is equally spaced.
Further, this divider wall top has a through hole to connect all vertical pore, and two openings of this through hole are at top, described divider wall two ends.
Beneficial effect of the present invention is:
1, the expansion joint of the divider wall both sides in technical solution of the present invention UNICOM not mutually makes the body of heater both sides coke powder can not intercommunication, has cut off the root of electric leakage.
2, passage distributes the heat that is delivered on the divider wall fast in the technical solution of the present invention, and the pressure to body of wall of having reduced to expand with heat and contract with cold has prolonged service life of body of wall.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical solution of the present invention is described in further detail.
Fig. 1 is the structural representation of prior art divider wall;
Fig. 2 is the structural representation of body of heater decompression divider wall of the present invention.
The specific embodiment
Fig. 1 is the structural representation of prior art divider wall.The prior art divider wall is to be built into by refractory brick, for the destruction that prevents to expand with heat and contract with cold to body of wall 1, prior art divider wall 1 leaves an expansion joint 2 every a segment distance, and this expansion joint 2 makes divider wall 1 both sides intercommunication, the coke powder of both sides is communicated, serious leaky is arranged.
Fig. 2 is the structural representation of body of heater decompression divider wall of the present invention.This divider wall 1 is to be made of refractory brick, equidistant some vertical pores 3 that distribute on the axis of this divider wall 1, and some vertical pores 3 equidistantly are to the unidirectional expansion joint of opening 2, divider wall 1 both sides respectively
Shape distributes, and expansion joint, both sides 2 does not overlap mutually.This divider wall 1 top has a through hole to connect all vertical pore 3, and two openings of this through hole are at top, described divider wall two ends.On the one hand, the expansion joint 2 of these divider wall 1 both sides is UNICOM not mutually, makes the body of heater both sides coke powder can not intercommunication, has cut off the root of electric leakage; On the other hand, passage 3 distributes the heat that is delivered on the divider wall 1 fast, and the pressure to body of wall of having reduced to expand with heat and contract with cold has prolonged service life of body of wall.
The invention is not restricted to the described scope of the foregoing description, every technology distortion of doing according to technical solution of the present invention all falls within protection scope of the present invention.
