Ungalihlonza kanjani ikhwalithi yenduku yensimbi engagqwali/ibha elinentambo/ibhawodi ye-stud?

1. Ukutholwa kukazibuthe

Uthe insimbi engagqwali ingakazibuthe, kunjalo! Kuyiqiniso futhi ukuthi akuyona kazibuthe! Eqinisweni, zihlukile. Sonke siyazi ukuthi insimbi engagqwali ihlukaniswe insimbi engagqwali ye-austenitic kanye nensimbi engagqwali ye-ferritic. Insimbi engagqwali ye-Austenitic ayiwona uzibuthe, kuyilapho i-ferritic insimbi engagqwali iyinsimbi enamandla kazibuthe. Ngochungechunge lwezilingo, kufakazelwa ukuthi insimbi engagqwali ye-austenitic izoba nozibuthe ocashile ngaphansi kwezimo ezithile ezikhethekile, kodwa ayiyona i-magnetic ngaphansi kwezimo ezivamile.

2. Yenza ukuhlolwa kwephuzu le-nitric acid

Ezimweni eziningi, kunzima ukuhlukanisa uchungechunge lwama-200, uchungechunge lwe-300, uchungechunge lwe-400 nezinye izinhlobo zensimbi engagqwali ngeso lenyama. Ukuhlolwa kwephoyinti le-nitric acid kuyindlela yokuhlola enembile kakhulu yokuhlola ukumelana nokugqwala kwe-substrate. Ngokuvamile, uchungechunge lwama-400 luzogqwala kancane kuphela phakathi novivinyo, kuyilapho uchungechunge lwensimbi engagqwali engu-200 olunokumelana nokugqwala okuphansi kakhulu luzoba namamaki okugqwala asobala.

3. Ukuhlolwa kokuqina

Uma insimbi engagqwali ye-austenitic izobonisa uzibuthe othile lapho amakhaza eginqika ngaphansi kwengcindezi yomoya, khona-ke ukuhlolwa kokuqala kazibuthe okusanda kushiwo akuvumelekile; ngakho-ke sidinga ukushisisa insimbi engagqwali ifike ku-1000-1100℃ bese siyicisha ngamanzi ukuze siqede amandla kazibuthe wensimbi engagqwali ye-austenitic futhi sivivinye ubulukhuni. Ubulukhuni bensimbi engagqwali ye-austenitic ngokuvamile bungaphansi kuka-RB85

Ngaphezu kwalokho

Ukuqina kwensimbi engu-430, 430F no-466 kungaphansi kuka-Rc 24

Ubunzima be-410, 414, 416 kanye no-431 yi-Rc36 ~ 43

Ukuqina kwensimbi ephezulu ye-carbon 420, 420F, 440A, B, C no-F yi-Rc50~60

Uma ubulukhuni bungu-Rc50~55, kungase kube insimbi engu-420

Ukuqina kwamasampula angu-440A kanye no-B acinyiwe ngu-Rc55~60

Inani le-Rc lika-60 noma ngaphezulu liyinsimbi engu-440C.

4. Ngokuhlola imishini

Uma insimbi engagqwali ehlolwayo imise okwe-shaft, kunconywa ukuthi uyiyise ku-lathe evamile noma i-CNC lathe ukuze ihlolwe ngomshini, kodwa kusenemikhawulo. Le ndlela ifaneleka kuphela kunsimbi okusika kalula kanye nensimbi engagqwali evamile, efana no-303, 416, 420F, 430F, 440F. Uhlobo lwensimbi lubonakala ngokuma kwama-chips aphendukayo. Lolu hlobo lwensimbi olulula ukusika luzokhipha iphunga elibi lapho luphendulwa esimweni esomile.

5. Ukutholwa kwe-Phosphoric acid

Lena indlela yokuthola esiyisebenzisa kakhulu ekuphileni kwansuku zonke. Le ndlela isetshenziselwa ukuhlukanisa insimbi engagqwali ye-chromium-nickel. Engeza i-phosphoric acid egxilile ku-0.5% yesisombululo se-sodium fluoride bese uyishisa ibe ngu-60-66℃.

6. Ukutholwa ngephuzu le-copper sulfate

Le ndlela ikwazi ukubona i-carbon steel evamile nensimbi engagqwali. Isixazululo se-copper sulfate kufanele sibe phakathi kuka-5% no-10%. Uma wehliswa phezu kwensimbi ezohlolwa, ungqimba lwethusi oluyinsimbi luzokwakheka phezu kwe-carbon steel evamile phakathi nemizuzwana embalwa, kuyilapho ingaphezulu lensimbi engagqwali ngokuyisisekelo lizohlala lingashintshile.

7. Ukutholwa kwesisombululo se-Sulfuric acid

Le ndlela ingahlukanisa izinsimbi ezingenasici ezingama-302, 304, 316, nezingu-317. Lungiselela i-sulfuric acid ene-concentration ye-20% kuya ku-30% kanye nezinga lokushisa elingaba ngu-70 ° C, bese ubeka insimbi ukuze ihlolwe kusixazululo. Izinsimbi ezingenasici ezingama-302 nezingu-304 zizokhiqiza inani elikhulu lamabhamuza lapho zihlangabezana nesixazululo futhi zizoba mnyama emizuzwini embalwa;

Ngokuphambene nalokho, ama-stainless steels angu-316 no-317 ngeke abonise ukusabela okukhulu esixazululweni, futhi ngokuyisisekelo ngeke abe mnyama phakathi kwemizuzu eyi-10 kuya kwengu-15.

8. Ukutholwa kwephuzu le-acid ebandayo

Uhlobo olufanayo lwensimbi engagqwali lungahlukaniswa ngokuconsa isixazululo esingu-20% se-sulfuric acid ebusweni besampula egayiwe, yapholishwa, yahlanzwa noma yapholishwa cishe.

Beka amaconsi ambalwa esixazululo se-asidi ebusweni besampula ngayinye. Ngaphansi kwesenzo sesisombululo se-asidi, izinsimbi ezingenasici ezingu-302 nezingu-304 zigqwalile kakhulu futhi ziphenduka zibe mnyama, zibonise omnyama-omnyama noma omnyama, bese kwakhiwa amakristalu aluhlaza esixazululo;

Insimbi engagqwali engu-316 igqwala kancane kancane futhi kancane kancane iphenduke ibe nsundu-phuzi, bese iba nsundu ibemnyama, bese ekugcineni yakha amakristalu amnyama ngokukhanyayo esixazululweni; Ukusabela okungenhla kwe-317 steel stainless kuqhubeka kancane.

9. Ukubuka ngezinhlansi

Ukuhlolwa kwenhlansi kusetshenziselwa ukuhlukanisa insimbi ye-carbon, i-structural alloy steel nensimbi yamathuluzi, kodwa akusebenzi kangako ekuhlukaniseni insimbi engagqwali. Le ndlela yokuhlola inhlansi ingasiza opharetha abanolwazi ukuba bahlukanise insimbi engagqwali ngezigaba ezine ezinkulu, kodwa akulula ukuhlukanisa phakathi kwamabanga ensimbi ahlukene.

Izimpawu ze-spark state zalezi zigaba ezine zemishini yensimbi engagqwali zimi kanje:

Ikilasi A: 302, 303, 316 insimbi, ekhiqiza izinhlansi ezibomvu ezimfishane ezinamafoloko amaningana.

Ikilasi B: 308, 309, 310 kanye nensimbi engu-446, ekhiqiza izinhlansi ezimbalwa ezimfushane ezibomvu ezimnyama ezinamafoloko amaningana.

I-Class C: 410, 414, 416, 430 kanye nensimbi engu-431, ekhiqiza izinhlansi ezimhlophe ezinde ezinamafoloko amaningana.

Ikilasi D: 420, 420F kanye ne-440A, B, C, F, ikhiqiza izinhlansi ezinemibala ecwebezelayo ezinokuphazima okusobala noma izinhlansi ezinde ezimhlophe.

10. Ngokutholwa kwe-hydrochloric acid

Le ndlela yokuthola ingahlukanisa 403, 410, 416, 420 insimbi engagqwali enokuqukethwe kwe-chromium ephansi kusukela ku-430, 431, 440, 446 insimbi engagqwali enokuqukethwe okuphezulu kwe-chromium

Chaza amanani alinganayo okusikwa kwesampula esixazululweni se-hydrochloric acid enomthamo wevolumu engu-50% cishe imizuzu emithathu, bese uqhathanisa ukushuba kombala wesixazululo. Insimbi enokuqukethwe kwe-chromium ephakeme inombala oluhlaza ngokumnyama.
