Abstract
The utility model relates to an interlinked inner heating graphitizing furnace, which comprises a furnace body, an inner lining, inner partition walls, and a pressurizing device which is arranged out of the furnace body. The utility model is characterized in that a plurality of groups of conductive electrodes and connecting electrodes are arranged inside the furnace body; the inner partition walls are arranged among the electrodes in the same group, and no inner partition wall is arranged between two adjacent groups of electrodes; blanks of the electrodes in the odd groups and the even groups of the utility model are energized alternately and are processed by graphitizing. The utility model has the advantages of high thermal efficiency, energy saving, and high productivity.
Description
The utility model relates to graphitizing furnace, hot graphitizing furnace in particularly a kind of combined.
In traditional acheson furnace, filled the resistance filler of high resistivity between the graphited electrode blank, electric current mainly produces joule heating in the resistance filler, account for 95%-98% of total joule heating, and the joule heating of the generation in electrode blank only has 2%-5%.Therefore blank mainly is by the thermal conduction heating of resistance filler, not only wastes electric energy, and has the temperature difference inside and outside the blank, and temperature distributing disproportionation is even in the stove, cause electrode blank axially, the radial degree of graphitization is inhomogeneous, directly influences the use properties of product.In recent years, large diameter Graphite Electrodes adopts concatenation type stove processing more, and electric current directly flows through from electrode blank self, and the high temperature that is heated to 2500-3000 ℃ by self joule heating is by graphitization processing uniformly.And existing cascade graphitizing furnaces is monomer structure, and thermo-efficiency is not high, and production efficiency is low.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and hot graphitizing furnace in a kind of combined that is made of several monomer cascade graphitizing furnaces is provided, and to satisfy the requirement of major diameter electrode blank graphitization processing, saves energy is boosted productivity.
Hot graphitizing furnace in the combined of the present utility model, comprise: body of heater, liner, internal partition wall, the conductive electrode of furnace wall is passed in body of heater one side setting, opposite side is provided with connection electrode, body of heater is provided with pressurizing device outward, it is characterized in that: some groups of conductive electrodes and connection electrode are set in the body of heater, between the same group of electrode internal partition wall are set, do not have internal partition wall between the two adjacent groups electrode.During work, between the conductive electrode of each electrode group and connection electrode, put several electrode blanks for the treatment of graphitization processing, between all electrode blanks, fill insulation material, by the outer pressurizing device of body of heater each electrode blank is compressed, alternately power up for the electrode blank of odd number group and even tree group, the alternate treatment some hrs can be finished the graphitization processing whole process of electrode blank.
Description of drawings of the present utility model is as follows:
Fig. 1 is its exemplary embodiments internal structure synoptic diagram.Wherein each part is: body of heater (1), liner (2), pass the conductive electrode (3) of furnace wall, connection electrode (4), internal partition wall (5) between first group of conductive electrode and the connection electrode, internal partition wall (6) between next group conductive electrode and the connection electrode, burner bus (7), burner copper polar plate (8), electrode blank (9), electrode blank (10), electrode blank (11), electrode blank (12), insulation material between the electrode blank (13) and be used for fixing the counter-force pillar (14) of connection electrode.According to the requirement of graphitization processing, 9-15 group conductive electrode and connection electrode can be set in the body of heater.
When graphitization processing, between first group of conductive electrode and connection electrode, put the two crosstalk utmost point blanks (9,10) for the treatment of graphitization processing, around electrode blank, fill insulation material (13), by the outer pressurizing device of the body of heater P that exerts pressure, send electricity, be warmed up to 2500-3000 ℃, continuous graphitization was handled 6-10 hours, outage, cooling, finished product is come out of the stove.
After first group of electrode blank send electricity, between second group of conductive electrode and connection electrode, put the two crosstalk utmost point blanks (11,12) for the treatment of graphitization processing, fill insulation material (13), pressurization ... after first group of power failure, give second group and send electricity, heat up, enter graphitization processing.Circulate so successively, successively the electrode blank of graphitization processing respective sets.
The utility model compared with the prior art advantage is as follows:
This internal heat type graphitizing furnace adopts the combined structure that is made of some monomer cascade graphitizing furnaces, joint Can, high productivity. Do not have internal partition wall between the two adjacent groups electrode, cost is low, the electrode of its odd number group and even number set Blank alternately powers up and carries out graphitization processing, when one group of electrode blank energising is processed, and the heat that insulation material scatters and disappears Amount conducts to insulation material and the electrode blank of adjacent set, the electrode blank of adjacent set is carried out preheating, when adjacent When the electrode blank of group was switched on, formerly the waste heat of material handling can also reduce the heat damage of current energising group Lose, so its thermal efficiency improves greatly than traditional burner.
It is big that the graphitized electrode of this graphitizing furnace has current density, lower than resistance, and uniformity is good, the characteristics that thermal shock resistance is big.
