Njira yotetezeka yogwiritsira ntchito crucible leak alarm chipangizo cha ng’anjo yosungunuka zitsulo

The crucible leakage alarm device of the chitsulo chosungunuka 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.

Chingwe chatsopano cha ng’anjo yosungunuka zitsulo chili kumayambiriro kwa kusungunuka kwa uvuni. Chifukwa cha kutsekemera kwa madzi ndi mpweya wa boric acid crystal madzi pamwamba pa chinsalu, kukana kwa kansalu kumachepa, ndipo kuwerenga kwa alamu ammeter kumakwera. Zikakhala zapamwamba, mtengo wa alamu ukhoza kufikidwa, koma panopa nthawi zambiri imakwera pang’onopang’ono panthawiyi. Pambuyo pa ng’anjo zingapo zitasungunuka, zimachepa pang’onopang’ono ndikubwerera kumalo abwinobwino, omwe amatha kusiyanitsidwa ndi ma alarm akutuluka. Nthawi zina alamu, yomwe yakhala ikutsika nthawi yowuma, imayambanso kuwuka. Panthawiyi, ng’anjoyo idawunikiridwa ndipo zidapezeka kuti chifukwa cha kusagwira ntchito mosasamala, scaffolding yachitsulo yowonjezera idapangitsa kuti kutentha kwachitsulo chosungunuka kukwera kwambiri ndikupitilira kutentha kwa sintering. (Pamwamba pa 1600 ° C), ng’anjo yonse ya ng’anjo imatenthedwa ndi pafupifupi wosanjikiza wovuta kwambiri komanso wovuta kwambiri, wopanda wosanjikiza wosinthika komanso wosanjikiza, motero kumayambitsa ngozi ya ng’anjo. Panthawi imeneyi, alamu yotulutsa ng’anjo mu uvuni ndiyolondola. Mng’anjo yapakatikati yosungunula ya 3t imagwiritsa ntchito chipangizo china chodzidzimutsa, chimodzi ndi chimodzi chodziwikiratu kutayikira. Chipangizocho chimaphatikizapo gawo lodziwikiratu lokhazikika lomwe limalumikizidwa ndi magetsi komanso kafukufuku wotsikira pansi womwe uli mu ng’anjo. Ngati madzi a alloy alumikizana ndi koyilo, kafukufuku woyambira pansi amatsogolera koyiloyo pansi, ndipo gawo lofufuzira loyambira lizizindikira ndikuzidula. Mphamvu yoletsa kuwonongeka kwa arc ya koyilo ndikuletsa madzi a alloy kuti asanyamule voteji yayikulu. Chipangizo choyezera kutayikira pansi chogwira pamanja chitha kugwiritsidwa ntchito pafupipafupi komanso pafupipafupi kuyang’ana ngati njira yowunikira kutayikira kwa ng’anjoyo ilibe bwino komanso yodalirika kuwonetsetsa kuti kafukufuku wotuluka pansi wakhazikika, kuti chitetezo cha wogwiritsa ntchito ndi ng’anjo ndi wotsimikizika.
