The ❖ kuyanika amagwira ntchito zovuta zimachitikira zitsulo ndi kusintha thupi ndi mankhwala pa ndondomeko kuwotcherera, makamaka kugonjetsa mavuto maelekitirodi kuwala pa kuwotcherera, kotero ❖ kuyanika ndi chimodzi mwa zinthu zazikulu zimene kudziwa ubwino wa weld zitsulo.
Kupaka kwa ma elekitirodi: kumatanthawuza nsanjika yomwe imakutidwa mofanana pamwamba pa nsonga yowotcherera pomangirira zinthu zopangidwa bwino ndi zinthu zosiyanasiyana zakuthupi ndi zamankhwala.
Udindo wa ❖ kuyanika elekitirodi: kupanga slag ndi oyenera thupi ndi mankhwala katundu monga kusungunuka, mamasukidwe akayendedwe, kachulukidwe, ndi alkalinity pa ndondomeko kuwotcherera, kuonetsetsa khola arc kuyaka, kupanga droplet zitsulo zosavuta kusintha, ndi kukhala kuzungulira arc zone ndi dziwe losungunuka Pangani mpweya kuti muteteze malo owotcherera, ndikupeza mawonekedwe abwino a weld ndi magwiridwe antchito.
Ndikothekanso kuwonjezera ma deoxidizers, ma alloying zinthu kapena kuchuluka kwa chitsulo chachitsulo pakupaka kuti akwaniritse zofunikira za chitsulo chowotcherera kapena kukonza magwiridwe antchito.
Zipangizo zowotcherera za Xinfa zili ndi zabwino kwambiri, chonde onani zambiri:https://www.xinfatools.com/welding-material/
Electrode arc kuwotcherera mfundo 1. Khungu la mankhwala 2. Solder pachimake 3. Gasi woteteza 4. Arc 5. Sungunulani dziwe 6. Zida zoyambira 7. Weld 8. Welding slag 9. Slag 10. Droplets
Zopangira zosiyanasiyana zitha kugawidwa kukhala:
(1) arc stabilizer
Ntchito yayikulu ndikupangitsa ma elekitirodi kukhala osavuta kugunda pa arc ndikusunga arc yoyaka mokhazikika panthawi yowotcherera. Zopangira zomwe zimagwiritsidwa ntchito ngati arc stabilizers makamaka zimakhala ndi zinthu zomwe zimakhala ndi zinthu zomwe zimakhala ndi ionized mosavuta zomwe zimakhala ndi mphamvu zochepa za ionization, monga feldspar, galasi lamadzi, rutile, titanium dioxide, marble, mica, ilmenite, kuchepetsa ilmenite, ndi zina zotero.
(2) Wopangira gasi
Mpweya umawonongeka pansi pa kutentha kwakukulu kwa arc, kupanga mpweya wotetezera, kuteteza arc ndi chitsulo chosungunula cha dziwe, ndikuletsa kulowetsedwa kwa mpweya ndi nayitrogeni mumlengalenga wozungulira. Zomwe zimagwiritsidwa ntchito kwambiri zopangira mpweya ndi carbonates (monga marble, dolomite, magnesite, barium carbonate, etc.) ndi zinthu zachilengedwe (monga ufa wamatabwa, wowuma, mapadi, utomoni, etc.).
(3) Deoxidizer (yomwe imadziwikanso kuti kuchepetsa wothandizira)
Kupyolera muzitsulo zachitsulo muzitsulo zowotcherera, mpweya wa okosijeni mu zitsulo zowotcherera umachepetsedwa, ndipo ntchito ya weld zitsulo imakhala bwino. Ma deoxidizers amakhala makamaka ma aloyi achitsulo ndi ufa wake wachitsulo wokhala ndi zinthu zolumikizana kwambiri ndi mpweya. Ma deoxidizers omwe amagwiritsidwa ntchito kawirikawiri ndi ferromanganese, ferrosilicon, ferrotitanium, ferroaluminium, ndi silicon-calcium alloys.
(4) Pulasitiki
Ntchito yayikulu ndikuwongolera mapulasitiki, kukhazikika komanso kusungunuka kwa zokutira pakuyika kwa ma elekitirodi atolankhani, kukulitsa luso la zokutira zama elekitirodi, ndikupangitsa kuti pamwamba pa electrode ikhale yosalala popanda kusweka. Nthawi zambiri, zida zokhala ndi kusalala, kuterera kapena kukulitsa zina pambuyo poyamwa madzi zimasankhidwa, monga mica, dongo loyera, titaniyamu dioxide, ufa wa talcum, galasi lamadzi olimba, mapadi, ndi zina zambiri.
(5) wothandizira wothandizira
Amagwiritsidwa ntchito kubwezera kuwonongeka kwa zinthu zowotcherera pakuwotcherera komanso kusintha zinthu zopangira ma weld kuti zitsimikizire kuti chitsulo chowotcherera ndi mankhwala. Ma ferroalloys osiyanasiyana (monga ferromanganese, ferrosilicon, ferrochrome, chitsulo, ferrovanadium, ferroboron, ferroboron, osowa dziko lapansi ferrosilicon, etc.) kapena zitsulo koyera (monga zitsulo manganese, zitsulo chromium, faifi tambala ufa, tungsten ufa, etc.) malinga ndi zosowa. dikirani).
(6) Wozembetsa
Panthawi yowotcherera, imatha kupanga slag yokhala ndi zinthu zina zakuthupi ndi zamankhwala, kuteteza madontho okotcherera ndi chitsulo chosungunuka cha dziwe, ndikuwongolera mapangidwe ake. Zopangira zomwe zimagwiritsidwa ntchito ngati zida za slagging zimaphatikizapo nsangalabwi, fluorite, dolomite, magnesia, feldspar, matope oyera, mica, quartz, rutile, titanium dioxide, ilmenite, etc.
(7) Binda
Pangani zinthu zokutira kuti zikhale zomangika mwamphamvu pachimake chowotcherera, ndikupangitsa kuti zokutira za elekitirodi zikhale ndi mphamvu zina zikauma. Alibe amawononga dziwe wosungunuka ndi kuwotcherera zitsulo pa kuwotcherera zitsulo. Zomangira zomwe zimagwiritsidwa ntchito kwambiri ndi galasi lamadzi (potaziyamu, sodium ndi galasi lawo lamadzi losakanikirana), phenolic r
