1. Okuqukethwe yizakhi ze-alloying.
Ngokuvamile insimbi ayigqwali kalula ngokuqukethwe kwe-chromium okungu-10.5%.Ukuphakama kokuqukethwe kwe-chromium ne-nickel, kuba ngcono ukumelana nokugqwala, njengokuqukethwe kwe-nickel engu-304 ku-8-10%, okuqukethwe kwe-chromium okungu-18-20%, insimbi engagqwali enjalo 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 kwezinga lokushisa kwe-billet kungaqinisekiswa, ngakho ikhwalithi yomkhiqizo izinzile futhi inokwethenjelwa, ikhwalithi enhle yangaphakathi, 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 eqhubekayo, noma indawo ene-acidity enkulu emoyeni kulula ukugqwala.304 impahla yensimbi engagqwali, uma indawo ezungezile impofu kakhulu izogqwala.
