Insimbi engagqwali isho ukumelana nokugqwala komoya, umusi, amanzi nokunye okubuthakathaka okucekela phansi, kanye ne-asidi, i-alkali, usawoti kanye namanye amakhemikhali aqoshwe ukugqwala okuphakathi kwensimbi, eyaziwa nangokuthi insimbi engagqwali engamelana ne-asidi. Yayisetshenziswa kabanzi ezindaweni ezahlukahlukene, okuhlanganisa ibhilidi, i-tableware, izinto zikagesi zasendlini, imboni, njll.Ngokwesakhiwo sensimbi, insimbi engagqwali yahlukaniswa yaba izinhlobo ezintathu, okuhlanganisa insimbi engagqwali eyiqiniso, insimbi engagqwali eqinile kanye nensimbi engagqwali ye-martensite. Ngokusekelwe kulezi zigaba ezintathu eziyisisekelo, kunezinye ezintathu ezingenasici. insimbi ukuze kuhlangatshezwane nezidingo nezimfuneko ezihlukahlukene.Lapho, i-SUS 340 ingeyensimbi engagqwali eqinisekisiwe, i-SUS 430 inamathela ensimbi engagqwali kanye ne-SUS 410,420 ihambisana nensimbi engagqwali ye-martensite.Nawu umehluko phakathi kwakho.
1.430 vs 304
Okokuqala, okuqukethwe kwe-chrome kwe-SUS 430 kufinyelela ku-16% -18% futhi ngokuyisisekelo ayinayo i-nickel. Futhi i-SUS 304 iqukethe kokubili. Ngakho, i-SUS 304 inokumelana nokubola okungcono. ye-SUS 304 iphakeme kune-SUS 430.
Ngaphezu kwalokho, i-SUS 430 isetshenziswa kakhulu endaweni yokuhlobisa izakhiwo, izinto zikagesi zasendlini, ingxenye yokushisisa uphethiloli.Futhi i-SUS 304 yayisetshenziswa kabanzi ekuhwebeni kwezimboni, ukuhlobisa ifenisha nokudla nempilo.Ekuqaleni, i-SUS 304 yasungulwa ukuze imelane. imvelo enobutha, njengendawo yogu, indawo ebandayo neswakeme.I-SUS 430 yayithambekele kakhulu ekusetshenzisweni endaweni enezinga lokushisa eliphezulu, njengebhayela, isilinda samanzi ashisayo, uhlelo lokuphakela ashisayo, njll.
1.410 vs 420 vs 430
410 - ubulukhuni kanye nokumelana okuhle nokuhunyazwa
420 — Insimbi ye-prop grade” ye-martensite, efana ne-brilliantine high chromium steel, insimbi engagqwali yakudala, nayo yayisetshenziswa emimese yokuhlinza futhi yayingenziwa ikhanye kakhulu.
430 - ngokuvamile njengenjongo yokuhlobisa, enokwakheka okuhle kakhulu, kodwa izinga lokushisa elikhona elibi nokumelana nokugqwala
Kunezici ezintathu eziyinhloko ezithinta imbangela yokugqwala kwensimbi engagqwali.
Okuqukethwe kwe-elementi ye-alloying
Ngokuvamile, kunzima ukugqwala uma okuqukethwe kwe-chromium kucishe kufinyelele ku-10.5%.Okusho ukuthi, ukuphakama kwe-chromium, kuba ngcono ukumelana nokugqwala.Isibonelo, ngokuvamile, okuqukethwe kwe-nickel kusondele ku-8% -10. % kanye nokuqukethwe kokugqwala kusondela ku-18% -20%, i-SUS 304 ngeke igle.
Inqubo yokuncibilikisa yebhizinisi lokukhiqiza
Ngenxa yobuchwepheshe obuhle kakhulu bokuncibilikisa, imishini ethuthukisiwe, ukulawulwa kwe-alloy element kanye nezinga lokushisa lokupholisa i-billet kanye nokususwa kokungcola kungaqinisekiswa kahle yifektri enkulu yensimbi engagqwali.Ngakho-ke, ikhwalithi yomkhiqizo ihle kakhulu futhi akulula ukugqwala.
Indawo yokuvikela
Imvelo enesimo sezulu esomile nesimo sokungena umoya kunzima ukugqwala. Futhi indawo enomswakama womoya omkhulu, isimo sezulu esinezimvula esilandelanayo, i-pH enkulu emoyeni kulula ukugqwala.
Inhloso ehambisanayo eyahlukene, yonke insimbi engagqwali inokusilela nobude bayo, isebenzisa izimboni ezahlukahlukene.
