Narkewar Injin Induction
An ƙera injin ...
Kamar yadda sunan ya nuna, tsarin ya ƙunshi narkewar ƙarfe a ƙarƙashin yanayin injin. Ana amfani da wutar lantarki wajen narkar da ƙarfe a matsayin tushen makamashi don narkar da ƙarfen. Narkar da wutar lantarki tana aiki ta hanyar haifar da kwararar wutar lantarki a cikin ƙarfen. Tushen shine na'urar induction coil, wacce ke ɗauke da wutar lantarki mai canzawa. Ruwan eddy yana zafi kuma daga ƙarshe yana narkar da wutar lantarki.
Tanderun ya ƙunshi jaket ɗin ƙarfe mai sanyaya ruwa wanda ba ya shiga iska, wanda zai iya jure wa injin da ake buƙata don sarrafawa. Ana narkar da ƙarfen a cikin wani bututun ruwa da aka sanyaya a cikin na'urar sanyaya ruwa, kuma galibi ana yi wa tanderun ado da kayan da suka dace.
Karfe da ƙarfe waɗanda ke da alaƙa da iskar gas - musamman nitrogen da oxygen - galibi ana narkar da su/a tace su a cikin tanderun injin don hana gurɓatawa/haɗawa da waɗannan iskar gas. Saboda haka, galibi ana amfani da wannan tsari don sarrafa kayan aiki ko kayan aiki masu tsafta waɗanda ke da juriya ga sinadaran da ke cikinsa.
Tambaya: Me yasa ake amfani da narkewar injin induction?
A: Narkewar injin injin an ƙirƙira shi ne da farko don sarrafa ƙarfe na musamman da na waje, kuma hakan ya zama ruwan dare gama gari saboda ana ƙara amfani da waɗannan kayan aikin zamani. Duk da cewa an ƙera shi don kayan aiki kamar superalloys, ana iya amfani da shi don ƙarfe na bakin ƙarfe da sauran ƙarfe.
Ta yayainjin dumama wutar lantarkiaiki?
Ana shigar da kayan cikin tanderun induction a ƙarƙashin injin kuma ana amfani da wutar lantarki don narke wutar. Ana ƙara caji don kawo ƙarar ƙarfen ruwa zuwa ƙarfin narkewa da ake so. Ana tace ƙarfen da aka narke a ƙarƙashin injin kuma ana daidaita sinadaran har sai an sami daidaiton sinadaran narkewa.
Me ke faruwa da ƙarfe a cikin injin tsabtace iska?
Musamman ma, yawancin karafa suna samar da wani Layer na oxide a kan kowace farfajiya da iska ta fallasa. Wannan yana aiki a matsayin garkuwa don hana haɗuwa. A cikin sararin samaniya, babu iska don haka ƙarfe ba zai samar da Layer na kariya ba.

Dangane da samfurin da tsarin ƙarfe, matakan injinan ...
Narkewa a ƙarƙashin yanayin da ba shi da iskar oxygen yana iyakance samuwar abubuwan da ba na ƙarfe ba kuma yana hana iskar shaka daga abubuwan da ke amsawa
Cimma nasarar jurewar abubuwan da ke cikin iskar gas da kuma juriyar haɗin gwiwa sosai
Cire abubuwan da ba a so ba tare da matsin lamba mai yawa na tururi
Cire iskar gas da aka narkar - iskar oxygen, hydrogen, nitrogen
Daidaita daidaiton haɗin ƙarfe mai kama da juna da zafin narkewa
Narkewa a cikin injin daskarewa yana kawar da buƙatar murfin slag mai kariya kuma yana rage yuwuwar gurɓatar slag ta hanyar bazata ko haɗawa a cikin ingot.
Saboda wannan dalili, ayyukan ƙarfe kamar dephosphorization da desulphurization suna da iyaka. VIM metallurgy galibi ana nufin halayen da suka dogara da matsin lamba, kamar halayen carbon, oxygen, nitrogen da hydrogen. Cire abubuwan da ke haifar da lahani, kamar antimony, tellurium, selenium da bismuth, a cikin tanderun induction na injin yana da matuƙar muhimmanci.
Sa ido kan yadda iskar carbon mai yawa ke aiki da matsin lamba don kammala deoxidation misali ne kawai na sauƙin amfani da tsarin ta amfani da tsarin VIM don samar da superalloys. Ana cire carbon, a cire sulfur ko a narkar da su a cikin tanderun injin don cika ƙa'idodi da kuma tabbatar da ingancin kayan. Saboda matsin lamba mai yawa na yawancin abubuwan da ba a so, ana iya rage su zuwa ƙananan matakai ta hanyar distillation yayin narkewar injin, musamman ga ƙarfe masu ƙarfi sosai a yanayin zafi mafi girma.

Ana iya haɗa hanyoyin masu zuwa cikin sauƙi tare da tsarin VIM don samar da narke mai tsabta:
Sarrafa yanayi tare da ƙarancin zubar ruwa da ƙimar fitar ruwa
Zaɓin kayan da suka fi karko don rufin da za a iya amfani da shi
Juyawa da daidaitawa ta hanyar motsa jiki ta hanyar lantarki ko iskar gas mai tsarkakewa
