Ubwino Wogwiritsa Ntchito Oxy-Acetylene Hardfacing Method

Njira yodziwika bwino ya oxyacetylene ndi iyi:

Kuchepetsa kuchepa kwa weld deposit,

Kuwongolera bwino kwa mawonekedwe a depositi,

Kutentha kochepa chifukwa cha kutentha pang'ono ndi kuzizira.

Njira ya oxyacetylene siyikulimbikitsidwa pazinthu zazikulu.

Zida zowotcherera mpweya wamba zimagwiritsidwa ntchito ponseponse.

Njirayi ndi yosavuta. Aliyense wodziwa kuwotcherera wamba sayenera kukhala ndi vuto kuphunzira zolimba nkhope pogwiritsa ntchito njirayi.

Pamwamba pa gawo lomwe liyenera kukhala lolimba liyenera kutsukidwa, popanda dzimbiri, sikelo, mafuta, dothi, ndi zinthu zina zakunja. Preheat ndi pambuyo-kutentha ntchito kuchepetsa kuthekera kwa ming'alu kukula mu gawo kapena maziko zitsulo.

Kusintha kwa lawi ndikofunikira mu njira ya oxyacetylene. Nthenga zochulukirapo za acetylene zimalimbikitsidwa poyika ndodo zolimba. Moto wosalowerera ndale kapena nthenga wamba amapangidwa pamene chiŵerengero cha okosijeni ku acetylene ndi 1:1. Lawi lokhazikika la nthenga lili ndi magawo awiri; phata lamkati ndi envelopu yakunja. Pakachulukirachulukira acetylene, pali gawo lachitatu, pakati pa phata lamkati ndi envelopu yakunja. Malowa amatchedwa nthenga ya acetylene yowonjezera. Nthenga zochulukirapo za acetylene zimatalika katatu ngati chulu chamkati chikufunidwa.

Pokhapokha pamwamba pa zitsulo zapansi m'dera lomwe limakhala lolimba kwambiri limabweretsedwa ku kutentha kosungunuka. Lawi lamoto la nyali limaseweredwa pamwamba pa zinthuzo kuti zikhale zolimba, zomwe zimapangitsa kuti nsonga ya mkati mwa chulucho ikhale yoyera. Mpweya wochepa wa carbon umalowetsedwa pamwamba, kutsitsa malo ake osungunuka ndi kutulutsa madzi, maonekedwe onyezimira omwe amadziwika kuti 'kutukuta'. Ndodo yolimba imalowetsedwa mumoto ndipo dontho laling'ono limasungunuka pamtunda wa thukuta, kumene limafalikira mofulumira komanso mwaukhondo, mofanana ndi alloy brazing.

Kenako ndodo yolimba imasungunuka ndikufalikira pamwamba pazitsulo zapansi. Zida zolimba siziyenera kusakanikirana ndi chitsulo choyambira koma ziyenera kugwirizana ndi pamwamba kuti zikhale zosanjikiza zatsopano zoteteza. Ngati kuchepetsedwa kwakukulu kumachitika, mphamvu za zinthu zolimba zimawonongeka. Pamwamba pamakhala wosanjikiza watsopano woteteza. Ngati kuchepetsedwa kwakukulu kumachitika, mphamvu za zinthu zolimba zimawonongeka.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
