$Electrode hard breakage is the breakage of a sintered electrode in the area below the conductive clamp: Operation problem: In production the operator should strictly observe the operational requirements and follow the established production process for adding paste and maintaining the electrode. Add the paste in an unreasonable manner electrode paste contaminated by dust or debris will be added to the electrode cylinder, electrode cylinder is not covered, when the dust collection is not handled in a timely manner dust falls into the electrode cylinder, so that the electrode paste delamination; in the addition of electrode paste is not in accordance with the process requirements of the height and the number of times to add the electrode paste, resulting in the electrode paste column is too low, which will cause the electrode cylinder spreading of yellow smoke, the volatile components of the rapid volatile components to complete the upper and lower electrode paste adhesion; the paste column is too high, resulting in overhanging paste. Too high, resulting in hanging paste. The above reasons are due to the plant workers do not strictly in accordance with the operating requirements and the production process caused by the electrode hard break. Example: in China's Northwest a calcium carbide plant 16500kVA calcium carbide furnace, charging system to remove dust is poor, the silo and in the three-phase electrode cylinder above, because the electrode cylinder is not covered, the silo leakage will fall into the electrode powder inside the cylinder, after a period of time, the electrode pressure to the copper tile below, it will be in the tip of the tile Qiqi hard break, fracture is very flat, the reason for the exhaustion down to the electrode cylinder found to have fallen into the furnace charge powder caused by the incident, the reference equipment in the electrode cylinder, after the electrode is not in accordance with strict operational requirements and production processes caused by the electrode hard break. After referring to the equipment in the three-phase electrode cylinder on the cover, to avoid the fall of dust. The problem was solved. India, a calcium carbide plant 30000kVA closed calcium carbide furnace in the new furnace, the three-phase electrode paste column once installed in the conductive clamps above 8m, two days after the power supply time, more than one batch of measurements of the three-phase electrode paste column do not change the reason for the discovery of the electrode cylinder electrode suspension paste, the use of the two-phase electrodes to cut the holding cylinder, electrode shells dealt with down, there is a very difficult to deal with a phase down to the electrode tube yellow smoke, volatile Points completely volatilized, resulting in the upper and lower bonding and hard break.
