Insimbi engagqwali iyinto eguquguqukayo futhi esetshenziswa kabanzi emikhakheni eyahlukahlukene. Ukumelana kwayo nokugqwala, amandla, kanye nokukhanga kwayo kuyenza ibe ukukhetha okuthandwayo kwezinhlelo zokusebenza ezahlukahlukene. Kungakhathaliseki ukuthi usebenza kuphrojekthi yokwakha, ukuklama umkhiqizo omusha, noma ufuna izinto ezingamelana nezimo ezinzima, ukukhetha insimbi engagqwali ephelele kubalulekile. Kulesi sihloko, sizokuqondisa ngenqubo yokukhetha insimbi engagqwali efanele izidingo zakho ezithile.

Ukuqonda Insimbi Engagqwali

Insimbi engagqwali uhlobo lwe-alloy yensimbi eyakhiwe ngensimbi, i-chromium, nezinye izinto ezifana ne-nickel, i-molybdenum, ne-manganese. Ukwengezwa kwe-chromium kunikeza insimbi engagqwali izakhiwo zayo ezingamelani nokugqwala. Ukwakheka okuqondile kwensimbi engagqwali kungahluka kuye ngebanga kanye nokusetshenziswa okuhlosiwe.

Amazinga ahlukene ensimbi engagqwali anikeza amazinga ahlukene okumelana nokugqwala, amandla, kanye nezinye izakhiwo. Amazinga asetshenziswa kakhulu afaka phakathi u-304, 316, 430, kanye no-201. Amazinga ngalinye anezici zalo ezihlukile futhi afanele ukusetshenziswa okuhlukile.

Igama elithi “insimbi engagqwali” alibhekiseli nje kuphela ohlotsheni lwensimbi engagqwali, kodwa futhi libhekisela namakhulu ezinhlobo ezahlukene zensimbi engagqwali. Kuzoba nzima kancane uma ukhetha insimbi engagqwali efanelekile yomkhiqizo wakho wokusetshenziswa.

Ngakho-ke ungayisebenzisa kanjani insimbi engagqwali efaneleke kakhulu ngokwesidingo sakho?

1. Kuhlukaniswe ngokushisa kwenqubo

Nakuba iningi lensimbi engagqwali linephuzu lokuncibilika eliphakeme, izinhlobo ezahlukene zensimbi engagqwali zihlukile. Njengoba iphuzu lokuncibilika lensimbi engagqwali engu-316 lingaba ngu-1375 ~ 1450℃. Ngakho-ke, lihlukaniswa ngobuningi ngokusebenzisa izinga lokushisa kanye nephuzu lokuncibilika.

2. Ukucabangela ukumelana nokugqwala

Ukumelana kwayo nokugqwala kungenye yezizathu ezenza abakhiqizi abaningi bafane kakhulu nensimbi engagqwali kunensimbi evamile. Kodwa-ke, akuzona zonke izinhlobo zensimbi engagqwali ezimelana ngokulinganayo nokugqwala, ezinye izinhlobo zensimbi engagqwali zingamelana kangcono nezinhlobo ezithile zamakhemikhali ane-asidi. Insimbi engagqwali ye-Austenitic efana nensimbi engagqwali engu-304 noma engu-316 ivame ukuba nokumelana nokugqwala okungcono kunezinye izinhlobo zensimbi engagqwali. Lokhu kungenxa yokuthi insimbi engagqwali ye-austenitic inokuqukethwe okuphezulu kwe-chromium, okusiza ukuthuthukisa ukumelana nokugqwala (yize ingaqinisekisi ukumelana nazo zonke izinhlobo zokugqwala).

3. Ukukhuluma ngesimo sesicelo ngokucabangela

Qinisekisa ukuthi umkhiqizo osetshenziswayo unamandla okuthwala. Sidinga ukucabangela amandla awo okudonsa lapho sikhetha izinto zensimbi engagqwali. Amandla okudonsa yinani elibalulekile lokushintsha kwensimbi kusuka ekuguqukeni kwepulasitiki okufanayo kuya ekuguqulweni kwepulasitiki okugxilile endaweni. Ngemva kokuba inani elibalulekile selidluliwe, insimbi iqala ukuncipha, okungukuthi, ukuguquguquka okugxilile kwenzeka. Iningi lezinsimbi ezingagqwali linamandla aphezulu okudonsa.
