Electrode suspension paste is the electrode paste block stuck in the electrode barrel can not fall, so that the electrode paste in the middle of a large gap.
When the paste is suspended, when measuring the electrode paste column, the paste column does not change for a long time, and if the time is longer, the electrode cylinder will emit a lot of yellow smoke.
If the suspended paste is not handled in time, it will cause a hard or soft break of the electrode, or even an explosion in the electrode barrel.
The reason of electrode suspension paste: the electrode paste block is too big, which is stuck in the electrode shell rib plate.
The paste column is too high and the temperature on the upper part of the electrode is too low to melt and sink.
In winter, the temperature is low, the heating element is off;
A large foreign body fell into the electrode barrel and blocked the electrode paste.
A 33000 kva sealed calcium carbide factory in Inner Mongolia electrode furnace, the coldest in January day stylish furnace, furnace when considering the electrode paste column is high, the strength of the sintered electrodes, the three-phase electrode paste column height to the more than 8 m, the three-phase electrode are hanging paste, two phase electrode cut down holding tube processing, another phase can't handle down to the last electrode tube take rust-worn gears flaking and hard to break.
To prevent electrode suspension paste, the electrode paste must be added according to the height and particle size required by the process.
When the temperature is low in winter, turn on the heater continuously and cannot be stopped;
The electrode barrel is capped to prevent foreign bodies from falling.
Every 4h to measure the height of the paste column once, continuous 8h without change, we have to deal with.
The solution is to drop a heavy object with a rope;
With oxygen welding will control tube, electrode tube cut open, with steel drill down.
