I-coating idlala indima ekuphenduleni okuyinkimbinkimbi kwe-metallurgical kanye nezinguquko zomzimba namakhemikhali ngesikhathi senqubo yokushisela, ngokuyisisekelo ukunqoba izinkinga zama-electrode okukhanya ngesikhathi sokushisela, ngakho-ke ukugqoka kungenye yezinto eziyinhloko ezinquma ikhwalithi yensimbi yokushisela.
I-Electrode coating: ibhekisela kungqimba olunamathelayo olumbozwe ngokulinganayo phezu komgogodla wokushisela ngokuhlanganisa izinto ezinohlamvu olucolekileyo ezinezakhiwo ezahlukene zomzimba namakhemikhali.
Indima ye-electrode coating: ukwakha i-slag enezici ezifanele zomzimba namakhemikhali ezifana nendawo encibilikayo, i-viscosity, ukuminyana, kanye ne-alkalinity ngesikhathi senqubo yokushisela, ukuqinisekisa ukushiswa kwe-arc okuzinzile, ukwenza i-droplet metal kube lula ukuguquka, futhi ezungeze i-arc zone nechibi elincibilikisiwe Dala umoya ukuze uvikele indawo yokushisela, futhi uthole ukwakheka okuhle kokushisela nokusebenza.
Kungenzeka futhi ukwengeza ama-deoxidizers, izakhi ze-alloying noma inani elithile le-iron powder enamathela ukuze kuhlangatshezwane nezidingo zokusebenza kwensimbi ye-weld noma ukuthuthukisa ukusebenza kahle kwe-deposition.
Izinto zokushisela ze-Xinfa zinekhwalithi enhle kakhulu, sicela uhlole imininingwane:https://www.xinfatools.com/welding-material/
Electrode arc welding principle 1. Isikhumba sezidakamizwa 2. Solder core 3. Protective gas 4. Arc 5. Melt pool 6. Base material 7. Weld 8. Welding slag 9. Slag 10. Amaconsi
Izinto ezisetshenziswayo ezihlukahlukene zingahlukaniswa zibe:
(1) i-arc stabilizer
Umsebenzi oyinhloko ukwenza i-electrode ibe lula ukushaya i-arc futhi igcine i-arc ivutha ngokuqinile ngesikhathi senqubo yokushisela. Izinto zokusetshenziswa ezisetshenziswa njengeziqinisi ze-arc ngokuyinhloko ziyizinto eziqukethe inani elithile lezinto ezenziwe kalula ze-ionization ezinamandla aphansi e-ionization, njenge-feldspar, ingilazi yamanzi, i-rutile, i-titanium dioxide, imabula, i-mica, i-ilmenite, i-ilmenite encishisiwe, njll.
(2) I-ejenti ekhiqiza igesi
Igesi ibolile ngaphansi kokushisa okuphezulu kwe-arc, yakha umkhathi ovikelayo, ivikela i-arc nensimbi ye-pool encibilikisiwe, futhi ivimbele ukungena komoya-mpilo ne-nitrogen emoyeni ozungezile. Ama-agent akhiqiza igesi asetshenziswa kakhulu yi-carbonates (njengemabula, i-dolomite, i-magnesite, i-barium carbonate, njll.) kanye nezinto eziphilayo (njengofulawa wezinkuni, isitashi, i-cellulose, i-resin, njll.).
(3) I-Deoxidizer (eyaziwa nangokuthi i-ejenti yokunciphisa)
Ngokusabela kwamakhemikhali e-metallurgical enqubweni yokushisela, okuqukethwe komoya-mpilo ensimbi ye-weld kuyancishiswa, futhi ukusebenza kwensimbi yokushisela kuyathuthukiswa. Ama-deoxidizers ikakhulukazi ama-alloys ensimbi kanye nezimpushana zawo zensimbi eziqukethe izakhi ezinokuhlobana okuphezulu komoyampilo. Ama-deoxidizer asetshenziswa ngokuvamile ahlanganisa i-ferromanganese, i-ferrosilicon, i-ferrotitanium, i-ferroaluminum, ne-silicon-calcium alloys.
(4) Ipulasitiki
Umsebenzi oyinhloko ukuthuthukisa ipulasitiki, i-elasticity kanye ne-fluidity ye-coating ye-coating in the process of electrode press coating, ukuthuthukisa ikhwalithi ye-electrode coating, nokwenza ubuso be-electrode coating bushelelezi ngaphandle kokuqhekeka. Ngokuvamile, izinto zokwakha ezinokuqina okuthile, ukushelela noma izici ezithile zokunweba ngemva kokumunca amanzi zikhethwa, njenge-mica, ubumba olumhlophe, i-titanium dioxide, i-talcum powder, ingilazi yamanzi eqinile, i-cellulose, njll.
(5) i-ejenti yokuxuba
Isetshenziselwa ukunxephezela ukulahleka kokushiswa kwezakhi ze-alloying ngesikhathi sokushisela kanye nokuguqula izakhi ze-alloying zibe i-weld ukuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zensimbi yokushisela. Ama-ferroalloy ahlukahlukene (njenge-ferromanganese, i-ferrosilicon, i-ferrochrome, insimbi, i-ferrovanadium, i-ferroboron, i-ferrosilicon yomhlaba engavamile, njll.) noma izinsimbi ezihlanzekile (njenge-metal manganese, i-chromium yensimbi, i-nickel powder, i-tungsten powder, njll.) ngokwezidingo. linda).
(6) I-ejenti ye-slagging
Ngesikhathi sokushisela, ingakha i-slag enezici ezithile zomzimba namakhemikhali, ivikele amaconsi e-welding kanye nensimbi ye-pool encibilikisiwe, futhi ithuthukise ukwakheka kwe-weld. Izinto zokusetshenziswa ezisetshenziswa njengama-slagging agents zihlanganisa imabula, i-fluorite, i-dolomite, i-magnesia, i-feldspar, i-white Mud, i-mica, i-quartz, i-rutile, i-titanium dioxide, i-ilmenite, njll.
(7) Isibopho
Yenza izinto zokumboza ziboshwe ngokuqinile kumgogodla we-welding, futhi wenze ukugqoka kwe-electrode kube namandla athile ngemva kokumisa. Ayinawo umthelela omubi echibini elincibilikisiwe nensimbi yokushisela ngesikhathi sokushisela i-metallurgy. Izibophezelo ezivame ukusetshenziswa yingilazi yamanzi (i-potassium, i-sodium kanye nengilazi yamanzi axutshwe), i-phenolic r
