B-85 Hardfacing Welding Electrode ndi makina apadera oyeretseraNdodo YolimbaChopangidwa kuti chiziyika pamalo osawonongeka kwambiri pazinthu zomwe zimakhudzidwa ndi kukwawa kwambiri, kukangana, komanso kukhudzidwa pang'ono. Chokhala ndi utoto wochuluka wa chromium, ndodo iyi yolumikizira arc imapanga zophimba zoteteza zomwe zimasunga umphumphu m'malo otentha kwambiri komanso owononga. Choyenera kumanganso ndi kuteteza zida zamafakitale, Hardfacing Rod iyi imawonjezera nthawi yogwirira ntchito m'malo ovuta kugwira ntchito.
Elekitirodi'Kapangidwe kake kapadera ka chromium flux kamalola chitsulo chosungidwacho kupanga kapangidwe kolimba komanso kolimba. Khalidwe lachitsuloli limapereka kukana kwakukulu ku kuboola, kupukuta, ndi kuwonongeka komwe kumachitika chifukwa cha mchere, miyala, ndi matope okwiyitsa. Chophimbacho chimateteza bwino zinthu zoyambira kuti zisawonongeke, ngakhale zitayikidwa kutentha mpaka madigiri 600.°C (1112)°F) kapena mlengalenga wowononga womwe umapezeka kwambiri m'migodi, simenti, ndi ntchito zogwirira ntchito.
Chofunika kwambiri pa ntchito yake ndi makhalidwe abwino kwambiri a makina omwe amaperekedwa ndi B-85.Ndodo Yolimba. Ikagwiritsidwa ntchito m'magawo awiri monga momwe akulangizidwira, chotenthetseracho chimafika pamlingo wovuta wa 57–62 HRc (muyeso wa Rockwell C). Kulimba kwambiri kwa pamwamba kumeneku kumalimbana mwachindunji ndi kutayika kwa zinthu chifukwa cha kusweka ndi kupukutidwa kwambiri, ngakhale kuti malo osungiramo zinthu sayenera kukhudzidwa kwambiri kapena kumenyedwa kwambiri chifukwa cha kusweka kwake pamlingo uwu wolimba.
Ndodo iyi imagwira ntchito bwino kwambiri popanga zinthu monga ma crusher hammers, ma augers, mano a trencher, ma pulverizer rollers, ndi ma chute liners. Kukhazikika kwake kutentha kwambiri kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazigawo za uvuni ndi zida za uvuni. Ogwiritsa ntchito ayenera kuzindikira zoletsa zake zogwirira ntchito: ngakhale kuti sizimakhudzidwa ndi kukanda komanso kupsinjika pang'ono, pamwamba pake sipakhala kulimba kwa ntchito zomwe zimaphatikizapo kukanda kwambiri, kugwedezeka kwambiri, kapena kupindika kwakukulu. Kutentha koyenera kusanayambe kutentha komanso kolamulidwa pakati pa zinthu ndikofunikira kuti tipewe kusweka.
Kwa mafakitale omwe akulimbana ndi kusowa kwa zida zokwera mtengo, B-85Ndodo Yolimbaimapereka njira yodzitetezera yotsika mtengo. Kuphatikiza kwake ndi kuuma kwambiri (57–62 HRc), kukhazikika kwa kutentha/dzimbiri, komanso kukana kukwawa komwe kumakulitsidwa ndi chromium kumapangitsa kuti Hardfacing Rod iyi ikhale yofunika kwambiri pomanganso makina ofunikira. Ikagwiritsidwa ntchito moyenera mkati mwa malire ake okhudzidwa, imachepetsa kwambiri nthawi yogwira ntchito komanso ndalama zosinthira m'migodi, zitsulo, ndi magawo ogwirira ntchito zolemera.
