Compared with the imported similar products, the electric conducting sections of the utility model are respectively added by 0.65% and 2.2%, and the resistivity is reduced by 23%; the electric energy loss of the electrode itself is greatly reduced, and the heat generation is lightened; not only the spending of electric charge is saved, but also the oxidation loss is reduced, and the service life is extended; the product manufacturing cost of the utility model relates to one tenth of that of the imported products.
Description
(1) technical field
The utility model relates to super-huge graphite component---burner conductive electrode and the cross-over electrode that internal thermal serial graphitized stove uses
(2) background technology
To be used for the hot stove in electric arc furnaces and ore deposit be at high temperature as the Delanium goods of conductive electrode, finishes by amorphous carbon to change and become the good conductive material to the graphite lattice, and this technical process is called graphitization.General in the world graphitization technological method mainly contains the anti-method of Acheson's method and Karst.The graphitizing furnace of setting up according to above-mentioned two kinds of methods is called acheson furnace and internal thermal serial stove (LWG).Because the latter has advantages such as furnace temperature height, power consumption are low, be a large amount of in the world at present type of furnaces of using.China also progressively rises and develops in recent years.But because the cross-over electrode that uses in used conductive electrode of LWG burner and the stove need bear temperature about 3000 ℃ and the mechanical pressure about 10Mpa, and need to allow the above big electric current of 100KA to pass through, therefore require burner conductive electrode and cross-over electrode to have enough big conductive section, quite low resistivity and certain mechanical strength.
The domestic large-scale charcoal ink factory that is building has introduced the LWG stove technology of U.S.'s carbon/graphite company, and burner conductive electrode and cross-over electrode all use the graphite electrode of Φ 900mm to carry out machining and make, and be 2 years specified service life.Because the present domestic plain press of large diameter graphite product charcoal like this that still do not have to produce can only be from buying ready-made electrode abroad.The price of U.S.'s carbon/every furnace end electrode of graphite company in 2004 is 11117 dollars, and German Xi Geli (SGL) company price is 12195 dollars.The price of cross-over electrode is respectively 16497 dollars and 16821 dollars.Every LWG stove is actual to use 8 tons two burner conductive electrodes and the cross-over electrode of always weighing, and total price is roughly equal to 340,000 yuan of RMB.This price does not also comprise expenses such as value-added tax, tariff, insurance and packed and transported.
(3) summary of the invention
The purpose of this utility model is to be based on using domestic existing graphite product, and a kind of used super-huge graphite component of pin-connected panel of internal thermal serial graphitized stove of alternative import is provided.
For achieving the above object, the utility model is according to following technical scheme.Internal thermal serial graphitized stove mainly is made up of quadrel electrode ink (being called for short graphite side) with the super-huge graphite component of pin-connected panel, and the burner conductive electrode is made up of two or four graphite sides, and mirror image setting in twos.Between the graphite side with bonding or reinforce in the mode that an end of electrode is provided with securing member.
Cross-over electrode is provided with groove by two graphite side's assembly units, bonding forming on the assembly unit face of a graphite side, the assembly unit face setting of another piece graphite side and the boss that groove is complementary, and boss is inserted in the groove during two graphite side assembly units.In the bottom of groove or the table top of boss the hole of filled high-temperature curing agent is set.
For super-huge LWG stove, establish the hole of running through two graphite sides at the end or the central part of cross-over electrode, insert graphite rod in the hole as latching, to strengthen its mechanical strength.
The utility model is compared with the like product of import, and conductive section has increased by 0.65% and 2.2% respectively.Resistivity decreased 23%.Because conductive section increases, resistivity reduces, the electric energy loss of himself greatly descends, generating heat alleviates, and not only saves electricity charge expense, and has reduced oxidational losses, increases the service life.The manufacturing cost of product is about about 1/5th of import product.

Fig. 2 is the left view of the utility model cross-over electrode.
Fig. 3 is the front view of the utility model cross-over electrode.
(5) specific embodiment
Burner conductive electrode concrete structure is referring to Fig. 1.For bogey form by graphite side 1 and 2 two and between the two mirror image be provided as conductive electrode and use, can take mode bonding or that add securing member 3 to reinforce between the graphite side; For big stove by graphite side 1 and 2 each two form and between any two mirror image be provided as conductive electrode and use, or mode bonding or that add securing member 3 is reinforced graphite side.Four sides and two end faces to every graphite side will carry out machining, guarantee fineness, the depth of parallelism and the perpendicularity on each plane.It should be noted that securing member is not that exotic material constitutes, when the burner conductive electrode was installed, the securing member 3 of end guaranteed that it is near on the lateral surface of burner wall or build by laying bricks or stones in the burner body of wall.
The cross-over electrode concrete structure is referring to Fig. 2.It is provided with groove 4 by graphite side 1 and 2 two assembly units, bonding forming on the assembly unit face of a graphite side 1, the boss 5 that the assembly unit face setting of another piece graphite side 2 and groove 4 are complementary, graphite side 1 during with 2 assembly units of graphite side boss 5 be inserted in the groove 4.In the bottom of groove 4 or the table top of boss 5 hole 6 is set.
For super-huge LWG stove, required cross-over electrode super large, overlength so can establish the hole 7 of running through graphite side 1 and graphite side 2 at the end or the central part of cross-over electrode, are inserted with graphite rod as latching, to strengthen its mechanical strength in the hole.
