Ukunyusa i-AN348A

I-Flux yizinto eziphathekayo eziphathekayo zenziwe ngamachiza asetyenziselwa ukuququzelela iinkqubo zazo zonke iintlobo zokwelusa. Ndiyabulela, izinto ezifakwe kwiinkonzo zixhunyiwe. Enye yezinto ezidumiweyo eziphathekayo yi-AN348A.

Yintoni le nto isetyenziselwa?

I-Flux AN348A (i-GOST 9078-81) isetyenziselwa ukunyuka kwe-arc. Ikuvumela ukukhusela i-arc kunye ne-pool ye-weld kwimiphumo yemeko yendalo. Ukongezelela, ukuhamba komnxeba kunokunceda kwi-metallurgical processing of welds.

Xa i-welding (ehambayo) ijikeleza ihlanganiswe ngetambo. Ngenxa yoko, i-coefficient ye-thermal yobuchule iyanda. I-AN348A i-flux isetyenziselwa ukufakelwa kombane, ukukhusela indawo yokusebenza evela emoyeni nakwezinye iigesi. Oku kudala iimeko eziyimfuneko ukwenzela ukusebenza kakuhle, okuqinisekisa ukuba kwakhiwa umgca welded quality.

Indlela yokufaka isicelo

Ngokuqhelekileyo kunokwenzeka ukubuyisela izixhobo eziphukileyo kunye nezixhobo ngoncedo lokukhupha. Le ndlela ikugcina imali kunye nexesha. Inkqubo ayiyi kuhlala. Ndiyabulela kuye, akudingeki ukuba ulinde ixesha elide kwiindawo ezinqabileyo ezifanele "zize" kungekudala.

Kwi-welding process, u-AN348A kunye nomnxeba baxhaswa ndawonye kwi-arc zone zone. Apho, imida yesiseko sensimbi, i-wire kunye ne-flux iyancibilika. Ngenxa yoko, ukujikeleza kwe-arc kubonakala i-bubble enesigxina segesi kunye nezinto ezihambayo. Xa i-arc ishukumisela, ukuxhamla kwimeko etyhidiweyo kuphakama kummandla werhasi leweld. Kule meko, i-slag yenziwa. Oku kukuvumela ukuba ukhusele ummandla ovela emoyeni omoya, ongafuneki apha. Umthunzi we-welding uhlaziye kwaye uphumelele. Emva kokupholisa kwayo, i-slag iyakhutshwa kalula.

Ukongeza kwiipropati ezichazwe ngasentla, ukukhuphaza kukuvumela ukukhusela i-welder ukuba ingaphumeli i-gases eyingozi kunye nothuli.

I-Flux AN348A: iimpawu

Izinto ezibonakalayo zingumbala omnyama ombala. Ubungakanani babo bu malunga ne-0.35-0.5 ml. Iingqolowa kwisakhiwo sazo zifana neziqwenga zeglasi. Ubuninzi babo buninzi kwi-1.3-1.8 kg / dm ³ . Izinto kufuneka zigcinwe zome xa zisetyenzisiweyo. Ukuba akunjalo, kufuneka kumiswe. Ngenxa yoko, yomiswe iyure kwiqondo lokushisa lika-300-400 ^° C.

Esinye seziganeko ezibalulekileyo kwiifomethi ziyimisebenzi yazo yamachiza. Ku-AN348A eli xabiso likwinqanaba 0.7-0.75 Af. Oku kuthetha ukuba i-AN348A i-flux yile nxalenye esebenzayo. Kwinkqubo yokulusa usebenzisa i-material, i-radiation iyaphuma, ixabiso elihambelana nemimiselo enziwe ngemigangatho (engekho ngaphezu kwe-18 mcd / iyure).

Ukubunjwa kwe-flux kufaka i-silicon oxides (ukuya kwi-44% yomsindo opheleleyo wenkunkuma), i-manganese (ukuya kwi-38%), i-calcium (ukuya kutsho kwi-12%), i-magnesium (ukuya kwi-7%), i-aluminium (ukuya kwi-13%) kunye nentsimbi (ukuya kwi-2.2% %). Ukongeza, kukho isulfure kunye ne-phosphorus. Kukho neengqungquthela zangaphandle eziseleyo kwimveliso ngexesha lokuvelisa (njengama-residu amalahle, i-coke, i-graphite, i-chips zensimbi, njl.).

I-Flux AN348A ingasetyenziselwa kwiimeko ezahlukeneyo kunye nohlobo olubanzi lwamaqondo okushisa ambi. Akukhuthazwa ukuba uyisebenzise kwimimiselo yeNyakatho ngamaqondo aphantsi kakhulu (ngezantsi -30 ⁰ С).
