Ingabe Insimbi Engagqwali Ingenazo Izimbobo Ngempela?

Ukubuka konke
Insimbi engagqwali iyinto ethandwayo ezimbonini ezahlukahlukene, okuhlanganisa ezokwakha, ezimoto, kanye nezindiza. Izakhiwo zayo ezingagqwali kanye nokuqina kwayo kwenza kube ukukhetha okuhle kakhulu kwezicelo eziningi. Kodwa-ke, umbuzo owodwa ovame ukuvela ukuthi "insimbi engagqwali inezimbobo yini". Impendulo efanele iwukuthi, insimbi engagqwali evamile ayinazimbobo.
Kulesi sihloko sebhulogi, sizohlola isihloko se-porosity ensimbi engagqwali bese sinquma ukuthi ingabe iyimpahla ene-porous.

1. Kuyini Insimbi Engagqwali?

Okokuqala, sidinga ukwazi ukuthi iyini insimbi engagqwali?
Insimbi engagqwali uhlobo lwensimbi oluqukethe okungenani i-10.5% ye-chromium. Ezinye izakhi, njenge-nickel, i-molybdenum, ne-titanium, zingase zengezwe ukuze kuthuthukiswe izakhiwo zayo zokumelana nokugqwala. Insimbi engagqwali yaziwa ngamandla ayo aphezulu, ukuqina, kanye nokumelana nokugqwala, okwenza kube kuhle ukusetshenziswa ezindaweni ezinzima.

Kodwa-ke, kunezinhlobo eziningana ezahlukene zensimbi engagqwali, ngayinye inezakhiwo zayo ezihlukile kanye nezici zayo. Njengensimbi engagqwali yase-Austenitic, ayinamandla kazibuthe futhi inokumelana okuhle kakhulu nokugqwala, kuyilapho insimbi engagqwali ye-ferritic inamandla kazibuthe futhi ayimelani nokugqwala kakhulu.

2. Ukugeleza Kwezinto Ezintweni

Ngemuva kwalokho sidinga ukwazi ukuthi iyini i-Porosity.
Ngamafuphi, i-Porosity ukuba khona kwezikhala ezingenalutho noma ama-pores ngaphakathi kwento. Izinto ezinezimbobo zinekhono lokumunca uketshezi namagesi, okungathinta izakhiwo zazo kanye nokuqina kwazo. I-Porosity ingaba ngokwemvelo kwezinye izinto, njengokhuni noma isiponji, noma ingaba umphumela wezinqubo zokukhiqiza, njengokukhipha noma ukushisela.

Ukuba khona kwe-porosity kungathinta kakhulu izakhiwo zemishini zento, njengokuqina, ukuguquguquka, kanye nokuqina. Izinto ezine-porous zingase zibe sengozini enkulu yokugqwala, njengoba ukuba khona kwe-voids kungadala izindlela zokuba izinto ezigqwalisayo zingene ngaphakathi kwento.

3. Ukumbozwa Kwensimbi Engagqwali

Insimbi engagqwali ingaba nezimbobo ngenxa yezici eziningana, okuhlanganisa izinqubo zokukhiqiza ezimbi, ukuchayeka ezindaweni ezigqwali, kanye nokuba khona kokungcola. Uhlobo oluvame kakhulu lwezimbobo ensimbi engagqwali yizimbobo eziphakathi kwe-granular, okubangelwa ukuna kwama-carbide emingceleni yokusanhlamvu ngesikhathi sokushisela.

I-porosity ephakathi kwe-granular inganciphisa kakhulu ukumelana nokugqwala kwensimbi engagqwali futhi ithinte izakhiwo zayo zemishini. Ezinye izinhlobo ze-porosity ezingase zenzeke ensimbi engagqwali zifaka phakathi i-porosity ebangelwa yi-hydrogen kanye ne-dendritic segregation.

4. Ukuhlolwa kwe-Porosity ngensimbi engagqwali

Kunezindlela eziningana zokuhlola ukuvuleka kwensimbi engagqwali, okuhlanganisa ukuhlolwa okubonakalayo, ukuhlolwa kokungena koketshezi, kanye ne-X-ray radiography. Ukuhlolwa okubonakalayo kuhilela ukuhlola ubuso bento ngokubonakalayo ukuze kutholakale izimpawu zokuvuleka, njengezikhala noma imifantu. Ukuhlolwa kokungena koketshezi kuhilela ukusebenzisa isixazululo sokungena ebusweni bento bese kusetshenziswa unjiniyela ukuze embule noma yiziphi iziphambeko ebusweni.

I-X-ray radiography iyindlela yokuhlola engonakalisi esebenzisa i-X-ray ukukhiqiza izithombe zesakhiwo sangaphakathi sento. Le ndlela iwusizo kakhulu ekutholeni ama-porosity angase abe khona ngaphansi kobuso bento.

5. Ukusetshenziswa kwensimbi engagqwali engeyona enezimbobo

Insimbi engagqwali engenazimbobo ibalulekile ezimbonini eziningana, okuhlanganisa ukucubungula ukudla, imithi, kanye namadivayisi ezokwelapha. Ubuso bensimbi engagqwali obungenazimbobo benza kube lula ukuyihlanza nokuyihlanza, okwenza kube yinto efanelekile yokusetshenziswa ezindaweni lapho ukuhlanzeka kubaluleke kakhulu.

Insimbi engagqwali ivame ukusetshenziswa ekwakhiweni kwezitshalo zamakhemikhali kanye ne-petrochemical, lapho ivezwa khona ezindaweni ezigqwali kakhulu. Insimbi engagqwali engenazo izimbobo iyadingeka kulezi zinhlelo ukuqinisekisa ukuthi izinto ziyamelana nokugqwala futhi zingamelana nezimo ezinzima.

Isiphetho

Ekuphetheni, insimbi engagqwali ingaba nezimbobo ngenxa yezici eziningana, okuhlanganisa izinqubo zokukhiqiza ezimbi, ukuchayeka ezindaweni ezigqwali, kanye nokuba khona kokungcola. Ukugqwala kwensimbi engagqwali kunganciphisa kakhulu ukumelana kwayo nokugqwala futhi kuthinte izakhiwo zayo zemishini.

Imibuzo Evame Ukubuzwa Mayelana Nensimbi Engagqwali Enezimbobo?

1. Iyini insimbi engagqwali, futhi kungani isetshenziswa?

Insimbi engagqwali uhlobo lwensimbi oluqukethe okungenani i-chromium engu-10.5%, enikeza le nto izakhiwo zayo ezihlukile, okuhlanganisa ukumelana nokugqwala, amandla, kanye nokuqina. Ivame ukusetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa ukwakhiwa, ezokuthutha, amadivayisi ezokwelapha, kanye nezinto zasendlini.

2. Ingabe insimbi engagqwali ingaba nezimbobo?

Yebo, ngaphansi kwezimo ezithile, insimbi engagqwali ingaba nezimbobo. Ukumbobo ensimbi engagqwali kungenzeka ngesikhathi senqubo yokukhiqiza, ikakhulukazi ngesikhathi sokushisela. Ezinye izinto ezingabangela ukumbobo zihlanganisa ukuchayeka ezindaweni ezigqwali kanye nokuba khona kokungcola ezintweni.

3. I-porosity ithinta kanjani izakhiwo zensimbi engagqwali?

Ukubhoboka kwensimbi kunganciphisa kakhulu ukumelana nokugqwala kwensimbi engagqwali, okwenza ibe sengozini yokugqwala. Kungaphinde kwenze buthaka impahla, kunciphise amandla ayo nokuqina kwayo.

4. Kutholakala kanjani ukubhoboka kwensimbi engagqwali?

Ukuhlola okubonakalayo kuyindlela elula yokuhlola ukubhoboka, kodwa kungase kungasebenzi kahle ekutholeni ukubhoboka okukhona ngaphansi kobuso bento. Ukuhlolwa kokungena koketshezi kanye ne-X-ray radiography kuyizindlela eziphumelela kakhulu zokuhlola ukubhoboka, njengoba kungathola amaphutha ebusweni kanye nokubhoboka okukhona ngaphansi kobuso bento.

5. Ingabe yonke insimbi engagqwali ayinazo izimbobo?

Cha, akuzona zonke insimbi engagqwali ezingenazimbobo. Ezinye izinhlobo zensimbi engagqwali zinezimbobo eziningi kunezinye, kuye ngokwakheka kwazo kanye nenqubo yokukhiqiza. Isibonelo, insimbi engagqwali engu-304 ngokuvamile ayinazimbobo, kuyilapho insimbi engagqwali engu-316 ingaba sengozini enkulu yokungena kwezimbobo ngenxa yokuqukethwe kwayo okuphezulu kwe-molybdenum.

6. Yiziphi izimboni ezithembele ensimbi engagqwali engenazimbobo?

Insimbi engagqwali engenazimbobo ibalulekile ezimbonini eziningana lapho ukuhlanzeka nokumelana nokugqwala kuyizinto ezibalulekile. Lezi zimboni zifaka phakathi ukucubungula ukudla, imithi, kanye namadivayisi ezokwelapha. Insimbi engagqwali isetshenziswa kakhulu ekwakhiweni kwezitshalo zamakhemikhali kanye ne-petrochemical, lapho ivezwa khona ezindaweni ezigqwala kakhulu.

7. Kungavinjelwa kanjani ukubhoboka kwensimbi engagqwali?
