Description
Technical Field
The utility model relates to the technical field of graphite, especially a sintering device for graphite electrode.
Background
Graphite is widely used as an electrode, and in the conventional technology for firing graphite electrodes, the graphite to be fired is generally formed by sintering in a manner of connecting the graphite blanks to be fired in series and electrifying the connected graphite blanks to be fired. To improve production efficiency, multiple electrodes are often connected in series while being fired electrically. Therefore, the graphite powder is added between the adjacent electrodes to be burnt to transmit current, but because the graphite powder is powdery, paper is needed to package joints during filling, the filling rate is slow, and the graphite powder is easy to scatter and pollutes a furnace chamber to cause loss.
In order to solve the problem, the proposal that the asphalt vitrolite block is adopted to replace graphite powder to fire the electrode is proposed, although the influence of the graphite powder on the heat preservation furnace charge is reduced to a certain extent, in the firing process, because the asphalt vitrolite block directly connects the graphite embryo to be fired together, the graphite embryo to be fired is heated unevenly, the electrode is easy to break, and the firing failure is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a device is fired in series connection of graphite electrode, its simple operation, electric conductive property are good, the energy can be saved, can improve and fire into power.
The problem is solved through following technical scheme:
a serial firing device for graphite electrodes comprises an electric furnace body, a power supply, a graphite blank to be fired, a first electrode, a second electrode and a graphite ring pad, wherein the first electrode is arranged on the electric furnace body; the first electrode and the second electrode are respectively assembled at two ends of the electric furnace body and are respectively connected with a power supply; the graphite ring gasket is assembled between the adjacent graphite blanks to be burnt.
The serial firing device for the graphite electrodes is additionally provided with a plurality of insulating columns, wherein the insulating columns are positioned among the graphite blanks to be fired and are assembled in the center of the graphite ring pad.
In the serial firing device for the graphite electrode, the outer diameter of the graphite ring pad is 100-1300 mm, the inner diameter is 70-1100 mm, and the thickness is 10-40 mm.
The utility model discloses a first electrode, the second electrode, graphite ring pad and power supply, adopt the mode of establishing ties and treating the graphite embryo of fever to treat the fever graphite embryo and fire, can effectively fire a large amount of qualified electrodes, and it adopts annular structure because graphite ring pad adopts as electrically conductive spare, the heat that produces by it can inside and outside give off simultaneously, the central authorities have been avoided because of the difficult disadvantage that gives off and burst of heat, than the graphite electrode firing device who does electrically conductive connecting piece with adoption graphite powder or waterlogged stone ink stick, not only fire evenly, can also avoid because graphite powder to the pollution of heat preservation furnace charge and other losses that cause.
The utility model discloses a graphite backing ring makes conductive parts, because it has burnt till in advance, shape and dimension are stable, the uniformity is good, and the external diameter of graphite backing ring is the same with the external diameter of waiting to burn the graphite embryo for when the installation, the installation is swift, uses manpower sparingly, improves the installation effectiveness, the save time cost. The insulating column is additionally arranged in the center of the graphite backing ring, and the insulating column is matched with the graphite backing ring to neatly draw a uniform overall size, so that graphite blanks to be fired which are connected in series are all in the same firing working condition, and the overall structures of the sintered finished graphite electrodes are completely consistent. The utility model discloses it is electrically conductive even, production efficiency is high, and energy loss is low to it is high to burn the product rate.
