Insimbi engagqwali imfushane ngensimbi yokugqwala ene-asidi, umoya, isitimu, amanzi nokunye okubuthakathaka okugqwala okuphakathi noma insimbi engagqwali kubizwa ngokuthi insimbi engagqwali;Futhi i-chemical corrosion resistance medium (i-asidi, i-alkali, usawoti kanye nokunye ukucwiliswa kwamakhemikhali) ukugqwala kwensimbi okubizwa nge-asidi steel.
Kunezici ezintathu eziyinhloko ezithinta ukugqwala kwensimbi engagqwaliamakheji ezifuywayoin Dalian:
1. Okuqukethwe kwezakhi ze-alloying.
Ngokuvamile insimbi ayigqwali kalula ngokuqukethwe kwe-chromium okungu-10.5%.Ukuphakama kokuqukethwe kwe-chromium ne-nickel, kuba ngcono ukumelana nokugqwala, okufana nokuqukethwe kwe-nickel okungu-304 ku-8-10%, okuqukethwe kwe-chromium okungu-18-20%, insimbi enjalo engagqwali ngokuvamile ayikona ukugqwala.
2, inqubo yokuncibilikisa yebhizinisi lokukhiqiza izophinde ithinte ukumelana nokugqwala kwensimbi engagqwali.
Ubuchwepheshe be-Smelting buhle, imishini ethuthukisiwe, inqubo ethuthukisiwe yesitshalo esikhulu sensimbi engagqwali noma ngabe ekulawuleni izakhi ze-alloy, ukususwa kokungcola, ukulawulwa kokushisa kwe-billet kungaqinisekiswa, ngakho ikhwalithi yomkhiqizo izinzile futhi inokwethenjelwa, ikhwalithi yangaphakathi enhle, akulula ukugqwala.Ngokuphambene nalokho, ezinye izinto ezincane zensimbi zibuyela emuva, inqubo yokubuyela emuva, inqubo yokuncibilikisa, ukungcola akukwazi ukususwa, ukukhiqizwa kwemikhiqizo kuzogqwala nakanjani.
3, imvelo yangaphandle, isimo sezulu esomile futhi imvelo umoya akulula ukugqwala.
Futhi umswakama womoya mkhulu, isimo sezulu esinemvula esiqhubekayo, noma indawo ene-acidity enkulu emoyeni kulula ukugqwala.304 impahla yensimbi engagqwali, uma indawo ezungezile impofu kakhulu izogqwala.
