Yakachengeteka nzira yekushandisa yecrucible leakage alarm mudziyo wesimbi inonyungudutsa choto

The crucible leakage alarm device of the simbi inopisa furna 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.

Rudzi rutsva rwevira rekunyungudusa simbi rwuri padanho rekutanga rekunyunguduka kwevheni yekubikira. Nekuda kwekushambadza kwemvura uye kunaya kwe boric acid crystal mvura pamusoro peiyo lining, kushomeka kweiyo lining kunoderera, uye kuverenga kwearamu ammeter kunokwira. Kana yakakwira, kukosha kwearamu kunogona kusvikwa, asi ikozvino kazhinji inokwira zvishoma nezvishoma panguva ino. Mushure mekunge mavira mashoma anyungudutswa, zvishoma nezvishoma anodzikira uye odzokera kune yakajairwa renji, iyo inogona kusiyaniswa kubva kune general leakage alarm ikozvino. Dzimwe nguva alarm current, iyo yanga ichidzikira panguva yekuoma, yakatanga kusimuka zvakare. Panguva ino, choto chakaongororwa uye zvakaonekwa kuti nekuda kwekushanda zvisina hanya, iyo yakawedzera iron material scaffolding yakaita kuti tembiricha yekunyunguduka yezasi yakanyunguduka ikwire zvakanyanya uye kudarika tembiricha yekupisa. (Pamusoro pe 1600 ° C), iyo yose vhezheni yevira inoputirwa neinenge chete yakanyanya vitrified uye yakaoma sintered layer, isina shanduko yekuchinja uye yakasununguka layer, zvichikonzera tsaona yekudonha kwechoto. Panguva ino, iyo yekuvuza yevira alarm panguva yeovheni ndeyechokwadi. Iyo 3t yepakati frequency yekunyungudutsa choto inoshandisa imwe aramu mudziyo, imwe neimwe yekudzika yekuona leakage yekuona mudziyo. Chishandiso ichi chinosanganisira dhizaini yekuona yepasi yakabatana kune magetsi uye yekuvhuvhuta probe iri muchoto. Kana iyo alloy fluid ikabata coil, iyo yekuvhuvhuta yepasi inotungamira iyo coil ikozvino pasi, uye iyo yepasi probe module inoiona uye yoigura. Simba rekupa kumisa kuparara kwearc yecoil uye kudzivirira iyo alloy fluid kutakura yakakwira voltage. Iyo inobatwa nemaoko ivhu yekuvuza probe test mudziyo inogona kushandiswa kugara uye kugara uchitarisa kana pasi pevuza probe system yechoto yakamira uye yakavimbika kuti ive nechokwadi chekuti pasi pevuza probe yakadzikwa zvachose, kuitira kuti kuchengetedzeka kweanoshanda uye choto chinovimbiswa.
