Ndodo Yowotcherera Yotsogola ya E312 Yowotcherera Yodalirika ya Chitsulo Chosapanga Dzimbiri

Ndodo Yowotcherera ya E312, yomwe imatchedwa AF312-16 pansi pa mayina wamba a mafakitale, ikuyimira chinthu chogwiritsidwa ntchito kwambiri chomwe chikugwirizana ndi muyezo wa dziko la China wa GB/T E312-16 komanso AWS A5.4 E312-16 yodziwika padziko lonse lapansi. Gululi limatanthauzira ngati yankho lofunikira kwambiri pakugwiritsa ntchito kwambiri kuwotcherera komwe kumaphatikizapo mitundu ina yachitsulo chosapanga dzimbiri ndi zinthu zovuta.

Chitsulo chachikulu cha elekitirodi iyi chimachokera ku chitsulo chosapanga dzimbiri cha Cr29Ni9. Chophimba chake cha elekitirodi chokhala ndi titanium-calcium chimathandiza kugwira ntchito mosiyanasiyana ndi magwero amphamvu a AC ndi DC, kupereka kukhazikika kwabwino kwa arc, kudontha pang'ono, komanso kuchotsa slag yosalala. Chofunika kwambiri, chitsulo chosungunula chomwe chili mu elekitirodiyi chimaphatikizapo zowonjezera za molybdenum ndi nayitrogeni, kuphatikiza ndi mpweya wochepa kwambiri. Kapangidwe kake ka mankhwala kolondola kameneka kamapangitsa kuti E312 Welding Rod ikhale yolimba kwambiri ku cracking cracking komanso kukana dzimbiri kwambiri, makamaka magwiridwe antchito abwino kwambiri motsutsana ndi stress corrosion cracking (SCC).

Yopangidwa kuti igwiritsidwe ntchito mofunikira, cholinga chachikulu chaNdodo Yowotcherera ya E312Ndi njira yolimba yolumikizira ndi kukonza zitsulo zosapanga dzimbiri zamitundu 29-9. Kapangidwe kake kapadera kamapangitsa kuti ikhale njira yabwino kwambiri yolumikizira zitsulo zosiyana (monga kulumikiza zitsulo zosapanga dzimbiri za austenitic ku zitsulo za kaboni kapena zitsulo zopanda aloyi ambiri) komanso kugwiritsa ntchito zinthu zomwe zimakhala ndi vuto la weld monga kusweka ndi ma pores. Kusavuta kugwiritsa ntchito chifukwa cha utoto wake kumawonjezera kuyenerera kwake kugwiritsa ntchito ma weld ovuta kapena ofunikira.

Kupatula zinthu zake zazikulu zophatikizira, kapangidwe ka electrode kamalinganizidwa bwino kuti kagwire bwino ntchito. Mtundu wa utoto wa titanium-calcium (titania-lime) sumangothandiza magwiridwe antchito abwino komanso umathandizira kukhazikika kwa arc ndi ubwino wa chitsulo chosungidwacho. Kapangidwe ka chitsulo chosungunuka kamene kamachokera ku weld kamagwiritsa ntchito zabwino zomwe zimapangidwa ndi duplex.，kuphatikiza mphamvu ya ferrite ndi kulimba ndi kukana dzimbiri kwa austenite，zomwe zawonjezeredwanso ndi zotsatira zabwino za Mo ndi N.

Makhalidwe aukadaulo aNdodo Yowotcherera ya E312, makamaka mtundu wake wodziwika bwino wa AF312-16, umaipanga ngati chida chofunikira kwambiri m'magawo ovuta monga kukonza mankhwala, kupanga magetsi, ndi uinjiniya wa m'madzi. Kuphatikiza kwake kosayerekezeka kwa kukana ming'alu yambiri, magwiridwe antchito abwino kwambiri a dzimbiri.–makamaka motsutsana ndi SCC–komanso kusinthasintha kwabwino kwa zinthu zovuta komanso zolumikizira zosiyanasiyana kumatsimikizira kuti kapangidwe kake ndi kolimba komanso kuti kamakhala nthawi yayitali m'malo ovuta kwambiri ogwirira ntchito, zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito bwino kwambiri.
