The crucible leakage alarm device of the ọkụ na-agbaze ígwè is necessary to ensure safe production, prevent the occurrence and expansion of furnace leakage accidents, help judge the use of the furnace lining, and prolong the furnace age. It is necessary to set up a crucible leakage alarm system. Generally, a direct current alarm device is used to install the stainless steel wire bottom electrode (first electrode) in contact with the molten iron and the stainless steel plate (mesh) side electrode (second electrode) between the induction coil of the furnace lining. Connect the electrode leads to the alarm device. When the molten metal leaks to the side electrode, the current rises to the set value, and the alarm device is activated. During the installation of the alarm device, it is necessary to check whether the connection between the lead wire and the electrode is good; whether the lead wire is grounded (resistance to ground> 5kC). During operation, sometimes the stainless steel wire melts at the bottom of the furnace. You can insert a conductive rod into the molten iron and use a multimeter to measure it. If the stainless steel wire is disconnected in the furnace lining, the alarm system will fail and it can only be laid when the furnace is rebuilt next time. After the alarm occurs, check whether it is a false alarm (false alarms mainly include: induced potential interference, lead wire grounding, and furnace lining wet). If the false alarm is eliminated, the furnace lining can be determined to be damaged.
